Barry PhilipsHalf Moon Bay, California, is one of the best destinations on the San Mateo Coast for people who love the outdoors. Famous for its dramatic Pacific Ocean scenery, sandy beaches, coastal bluffs, rolling hills, redwood forests, and peaceful countryside, the area offers an impressive variety of hiking experiences.
Whether you are looking for an easy coastal walk, a challenging mountain climb, a peaceful redwood forest hike, or a trail with spectacular ocean views, there are plenty of Half Moon Bay hiking trails worth exploring.
The beauty of hiking in Half Moon Bay is the diversity of its landscape. Within a relatively short distance, hikers can move from oceanfront bluffs to dense redwood forests and steep mountain ridges. The city also provides access to portions of the California Coastal Trail, while nearby parks and open-space preserves offer more challenging adventures.
Some trails are suitable for beginners and families, while others require good fitness, proper footwear, plenty of water, and experience with elevation changes.
Here are some of the top hiking trails in Half Moon Bay and the surrounding Coastside area.
Top Hiking Trails In Half Moon Bay
1. Half Moon Bay Coastal Trail
The Half Moon Bay Coastal Trail is one of the best choices for visitors who want beautiful scenery without committing to a strenuous hike.
This coastal pathway follows the shoreline and provides impressive views of the Pacific Ocean, beaches, coastal bluffs, and surrounding landscapes. It is particularly appealing to walkers, casual hikers, runners, and cyclists.
One of the biggest advantages of the trail is its relatively gentle character. You can enjoy the coastline at your own pace without having to tackle a major elevation gain.
The trail also provides opportunities to observe coastal birds, wildflowers, marine life, and occasionally whales offshore. The City of Half Moon Bay describes its Coastside Trail as a popular pedestrian and bicycle route along the bluffs with opportunities for wildlife and wildflower viewing.
For travelers who want an enjoyable introduction to hiking in Half Moon Bay, this is an excellent place to start.
Best for: Beginners, families, walkers, cyclists, ocean views
Difficulty: Easy
Highlight: Pacific Ocean and beach scenery
2. Cowell-Purisima Trail
The Cowell-Purisima Trail is one of the standout Half Moon Bay hiking trails for people who want a combination of ocean scenery, farmland, coastal vegetation, and wildlife.
Located just south of Half Moon Bay, this approximately 3.6-mile trail travels along coastal bluffs where agricultural land meets the Pacific Ocean. It forms part of the larger California Coastal Trail system.
The trail is generally gently graded, making much of it accessible to a wide range of hikers. There is, however, steeper terrain around the section where the trail crosses Purisima Creek.
As you hike, keep an eye out for harbor seals, pelicans, hawks, wildflowers, and other coastal wildlife. The landscape provides a wonderful contrast between open farmland and the vast Pacific Ocean.
One important consideration is that dogs are not permitted on the Cowell-Purisima Trail. The trail can also experience periodic closures because of weather, maintenance, and agricultural operations, so visitors should check conditions before setting out.
Best for: Coastal scenery, wildlife, moderate walks, nature lovers
Difficulty: Easy to moderate
Highlight: Ocean cliffs meeting coastal farmland
3. Purisima Creek Redwoods Trail
For hikers who want to escape the open coastline and enter a cooler, greener environment, Purisima Creek Redwoods is one of the best choices.
The Purisima Creek Redwoods Open Space Preserve features towering redwood trees, lush vegetation, ferns, creeks, and shaded forest paths. The atmosphere can feel completely different from the exposed coastal trails just a short distance away.
The Purisima Creek Trail provides an especially pleasant introduction to the preserve. The route passes through a redwood canyon with a year-round creek, while more ambitious hikers can continue deeper into the preserve and connect with longer routes.
This is particularly appealing on warmer days because much of the forest provides shade. The sound of running water, dense vegetation, enormous trees, and occasional wildlife make the experience feel peaceful and immersive.
Purisima Creek is also a good option when coastal fog obscures the ocean views. Instead of worrying about visibility, hikers can enjoy the forest environment.
Best for: Redwoods, shade, nature photography, peaceful hikes
Difficulty: Easy to challenging depending on route
Highlight: Redwood forest and creek scenery
4. Grabtown Gulch to Purisima Creek Loop
If you want a longer forest adventure, the Grabtown Gulch to Purisima Creek Loop is worth considering.
This route combines several sections of the Purisima Creek area and offers a more substantial hiking experience than a short out-and-back forest walk. The landscape includes redwoods, ferns, creekside areas, and dense woodland.
The loop is commonly described as a moderate hike of roughly 4.8 miles. It is popular with hikers and trail runners and provides a good balance between exercise and scenery.
Because this is a longer route with changing terrain, hikers should allow sufficient time and carry water. The forest environment can also become muddy following wet weather.
One of the attractions of this route is the sense of being immersed in nature. Instead of simply walking through a park, you spend much of the hike surrounded by mature forest.
Best for: Intermediate hikers, forest lovers, trail runners
Difficulty: Moderate
Highlight: Redwood forest and creek environment
5. Harkins Ridge, Craig Britton and Purisima Creek Trail
For hikers looking for a longer and more challenging redwood adventure, the Harkins Ridge, Craig Britton and Purisima Creek route offers an excellent combination.
This route explores several sections of the Purisima Creek preserve, allowing hikers to experience both creekside forest and higher ridge terrain.
The route is around seven miles and is generally regarded as a moderate hike. It provides the opportunity to spend several hours exploring the forest rather than simply taking a short nature walk.
The dense woodland, ferns, redwoods, creek crossings, and changing elevations make this an excellent choice for people who enjoy varied terrain.
Because the route is longer than many casual Half Moon Bay walks, preparation is important. Comfortable hiking shoes, water, snacks, and adequate time are recommended.
Best for: Experienced recreational hikers and forest exploration
Difficulty: Moderate
Highlight: Long-distance redwood hiking
6. Montara Mountain Trail
If your idea of a great hike involves climbing rather than simply walking along a flat coastal path, Montara Mountain Trail deserves serious consideration.
The trail begins in San Pedro Valley Park and gradually moves from eucalyptus forest into coastal scrub and manzanita vegetation. As the elevation increases, hikers encounter increasingly impressive views of the surrounding coastline.
The official trail information lists the Montara Mountain Trail at approximately 2.10 miles with an elevation change of about 1,174 feet and a strenuous rating.
The climb is the main attraction. Steeper sections and switchbacks provide a genuine workout, but the higher you go, the more rewarding the scenery becomes.
From the mountain and connecting routes, hikers can enjoy views toward the Pacific coast, Montara State Beach, Half Moon Bay, and the San Francisco Bay area.
This is one of the best hiking trails near Half Moon Bay for anyone who wants a serious physical challenge combined with panoramic scenery.
Best for: Experienced hikers, mountain climbing, panoramic views
Difficulty: Strenuous
Highlight: Elevation gain and expansive coastal views
7. Gray Whale Cove Trail
Gray Whale Cove Trail offers one of the classic coastal hiking experiences in the Half Moon Bay area.
The trail is located in McNee Ranch State Park and provides access to coastal scenery overlooking the Pacific Ocean. The surrounding landscape includes coastal scrub, rocky shorelines, hills, and spectacular ocean views.
The route is approximately one mile one way and is generally considered moderate because of the initial climb from the parking area. Once higher on the trail, the terrain becomes more manageable.
Spring can be an especially beautiful period to explore the area because wildflowers can transform the coastal landscape.
Hikers should be aware that coastal conditions can change quickly. Fog, wind, and sun can all be present during the same hike, so wearing layers is a smart choice.
Best for: Ocean views, wildflowers, wildlife watching
Difficulty: Moderate
Highlight: Pacific coastline and seasonal wildflowers
8. Pillar Point Bluff Trail
Pillar Point Bluff is another excellent option for people who want spectacular coastal scenery without a strenuous mountain climb.
The bluff-top environment provides sweeping views of the Pacific Ocean and the coastline. Depending on conditions and season, hikers may also have opportunities to observe seabirds and marine wildlife.
The trail is particularly attractive to visitors who want a relatively relaxed outdoor experience while still enjoying dramatic California scenery.
It is also a good option for people who do not have an entire day available for hiking. You can enjoy the landscape, take in the ocean views, and return without committing to a long backcountry-style hike.
Best for: Casual hikers, families, coastal views
Difficulty: Easy to moderate
Highlight: Coastal bluff scenery
9. Fitzgerald Marine Reserve Trails
Fitzgerald Marine Reserve, located in nearby Moss Beach, offers a different kind of hiking experience.
Instead of focusing primarily on elevation or distance, the trails allow visitors to explore coastal bluffs, cypress groves, marine habitats, and shoreline environments.
The reserve includes the Bluff Trail, Cypress Trail, and Dardenelle Trail. The Bluff Trail climbs through a cypress grove to the bluff top, while the Cypress Trail connects the coastal and bluff areas. The Dardenelle Trail forms part of the California Coastal Trail and is accessible to people with disabilities.
The reserve is particularly famous for its tidepools. However, tidepool exploration depends heavily on the tides, so visitors should plan accordingly.
This is an excellent destination for people who want to combine hiking with marine-life observation and coastal exploration.
Best for: Families, marine life, tidepools, nature enthusiasts
Difficulty: Easy
Highlight: Coastal bluffs, cypress groves, and marine habitats
10. Devil’s Slide Trail
Devil’s Slide Trail is one of the most distinctive trails near Half Moon Bay.
The route was created from a former section of Highway 1 and provides a paved multi-use path above the Pacific Ocean. It is suitable for hikers, runners, bicyclists, and equestrians. San Mateo County describes it as approximately 1.3 miles long.
The major attraction is the dramatic coastal setting. The trail follows the rocky heights above the ocean, offering expansive views and opportunities to watch birds and marine life.
Because it is paved and relatively short, Devil’s Slide can be a good option for visitors who want scenery without tackling a rugged hiking trail.
It is also a particularly attractive choice for sunrise, sunset, or a relaxed coastal outing, although visitors should always be aware of changing weather and wind conditions.
Best for: Beginners, runners, cyclists, coastal views
Difficulty: Easy
Highlight: Dramatic Pacific Ocean scenery
11. Purisima Creek Trail to Skyline Boulevard
For experienced hikers looking for a major challenge, the Purisima Creek Trail to Skyline Boulevard is one of the more demanding options in the region.
The route travels through dense redwood forest and follows creek areas before climbing toward Skyline Boulevard. It provides a substantially longer hiking experience than the shorter trails around Half Moon Bay.
The route is listed among the area’s more difficult hikes, with a distance of approximately 8.6 miles and an estimated hiking time of more than four hours.
The forest canopy provides shade, making the trail particularly appealing during warmer weather. However, the distance, elevation changes, and potentially wet or uneven terrain mean that it is best suited to hikers who are physically prepared for a long outing.
Best for: Experienced hikers, endurance training, redwood exploration
Difficulty: Hard
Highlight: Long forest hike and substantial elevation gain
12. Clipper Ridge and French Trail Loop
The Clipper Ridge and French Trail Loop is another good choice for hikers seeking a moderate challenge with excellent coastal views.
The route includes an initial steep climb before transitioning through areas with more gradual sections. As you gain elevation, the surrounding views open toward Pillar Point Harbor, Half Moon Bay, and the Pacific Ocean.
The route is approximately 3.2 miles and is commonly classified as moderate.
One thing to remember is that portions of the trail have limited shade. On sunny days, sun protection and sufficient drinking water become particularly important.
For hikers who want a relatively short route that still delivers elevation, exercise, and scenery, this can be a strong choice.
Best for: Moderate hiking, coastal views, fitness
Difficulty: Moderate
Highlight: Ridge views overlooking the ocean and harbor
13. Coastal Trail via Redondo Beach Road
Another excellent option for coastal scenery is the Coastal Trail via Redondo Beach Road.
The route follows coastal bluffs and offers beautiful views of the Pacific Ocean and surrounding coastal grasslands.
At approximately four miles, it provides more distance than a simple beach stroll while remaining relatively accessible to hikers who prefer coastal rather than mountainous terrain.
Birdwatchers can also find this type of coastal environment rewarding, with opportunities to observe different species moving through the grasslands and bluff areas.
This trail is particularly appealing when the goal is to spend time outdoors, enjoy ocean scenery, and get some exercise without undertaking a strenuous climb.
Best for: Coastal walking, birdwatching, ocean views
Difficulty: Easy
Highlight: Coastal grasslands and bluffs
How To Choose The Best Hiking Trail In Half Moon Bay
Choosing the right Half Moon Bay hiking trail depends largely on your fitness level, available time, weather, and the type of scenery you want.
If you want an easy walk with spectacular ocean scenery, the Half Moon Bay Coastal Trail, Devil’s Slide Trail, or Pillar Point Bluff are good options.
If you prefer forests and shade, Purisima Creek Redwoods should be near the top of your list.
For a combination of farmland and coastal scenery, Cowell-Purisima is an excellent choice.
If you want a serious workout, Montara Mountain provides substantially more elevation gain and a strenuous climb.
For wildlife and marine environments, Fitzgerald Marine Reserve is particularly appealing.
Best Time To Go Hiking In Half Moon Bay
Half Moon Bay’s coastal climate means that hiking conditions can vary considerably throughout the year.
Summer can bring cool coastal temperatures and fog, while sunny conditions may occur inland. Spring is particularly attractive for wildflowers along some coastal trails.
Fall can provide pleasant hiking conditions, while winter may bring wetter and muddier trails. Rain can also affect trail conditions, particularly in redwood preserves and areas around creeks.
Regardless of the season, hikers should check current trail conditions before leaving. Some trails may be temporarily closed because of weather, maintenance, agricultural activities, or other safety concerns. For example, San Mateo County notes that the Cowell-Purisima Trail can experience periodic closures.
What To Bring When Hiking In Half Moon Bay
Even an easy coastal walk deserves basic preparation.
Bring enough drinking water, particularly for exposed trails with little shade. Wear comfortable footwear appropriate for the terrain, and consider carrying an extra layer because coastal wind and fog can make conditions feel colder than expected.
Sun protection is also important. Coastal fog does not necessarily eliminate exposure to ultraviolet radiation.
For longer hikes, pack snacks or a small meal, a phone or navigation device, and basic first-aid supplies.
Stay on marked trails and avoid entering restricted areas. This is especially important around protected agricultural land, sensitive coastal habitats, cliffs, and marine mammal areas.
Hiking Safety Tips For Half Moon Bay Trails
The Pacific Coast is beautiful, but it can also be unpredictable.
Avoid getting too close to unstable cliff edges, particularly when strong winds are present. Never assume that a route is safe simply because another person has crossed an area.
Pay attention to trail signs and park regulations. On redwood trails, roots, mud, rocks, and creek crossings can create slippery conditions.
On exposed coastal routes, carry adequate water and wear sun protection. On mountain trails, allow extra time for steep climbs and descents.
If you are hiking alone, tell someone where you are going and approximately when you expect to return.
Most importantly, respect wildlife and natural habitats. Do not approach marine mammals, disturb tidepools, or remove plants, rocks, or other natural features.
