Channel Islands National Park, CA
Remote, ranger-led epic to roaring seal and sea lion colonies
Overview
This is San Miguel Island’s signature long walk: a ranger-led, out-and-back trek of about 16 miles total to the far-western headland of Point Bennett. It’s a full-day, strenuous undertaking thanks to length, constant wind, rolling terrain, and soft sand in places. Interior hikes on San Miguel—including this one—are only allowed with a National Park Service ranger, a rule tied to safety and resource protection.
For prepared hikers who crave remoteness, natural history, and a blockbuster wildlife finale, this is one of California’s great coastal adventures. For casual walkers, the distance, exposure, and guided-only access make it a tough fit.

Trail guide
From the Cuyler Harbor campground area, the route follows an old Navy road turned singletrack over San Miguel Hill (the island’s high point at 831 feet), dips through Sand Blast Pass, and rolls past landmarks like the Caliche Forest—fossilized tree casts from the last ice age—before skirting a dry lakebed/airstrip and continuing to Point Bennett. Expect roughly 1,500 feet of cumulative gain with multiple climbs and descents. The payoff is one of the world’s densest concentrations of seals and sea lions, viewed from an overlook near a research station. Throughout, you’ll get sweeping views of wind-carved hills and rugged coastline, with WWII history on San Miguel Hill adding a human layer to the landscape.
This hike is all about exposure: strong winds, big skies, no shade. Underfoot it’s mostly dirt with sections of soft sand. You’ll likely feel the distance—wind and sand make the miles punch above their weight. Typical group time is around six hours of hiking, but stops for ranger interpretation and wildlife viewing can extend the day. This is a remote, disciplined outing: you’ll stay on trail and with the ranger at all times.
Point Bennett is famous for its marine mammals—seals and sea lions in impressive numbers. Spring and early summer often bring especially lively scenes, including pups. Birdlife is a constant companion across the island’s open terrain.
San Miguel is reachable by boat with limited schedules, and many visitors stay overnight to make this hike feasible. Given weather-dependent landings and the distance, build flexibility into your plans. Bring ample water, food, sturdy boots, layers for wind and sun, and binoculars for the finale. You must remain with the ranger; off-trail travel is prohibited due to sensitive resources and lingering military hazards.
