Point Bennett - 16mi Strenuous Island Hike

white sand beach with seals and sea lions laying close to each other

This is maximum-difficulty backcountry island hiking. You'll cover 16 strenuous miles over rugged island terrain to observe massive seal and sea lion colonies—one of the park's most engaging wildlife experiences. The tactical reality: unexploded ordnance means federal law requires mandatory ranger accompaniment; you cannot hike unsupervised. The payoff: wildlife observation at a level most hikers never achieve.

Safety & strategy

Hazards: Unexploded ordnance
Mandatory ranger accompaniment required
Remote island location
Coastal wind exposure
Dehydration risk over 16 miles
Hazard Details: Unexploded ordnance present—visitors MUST be accompanied by ranger beyond ranger station (federal law). Island is former Navy bombing range. No off-trail hiking permitted. Remote location with exposure to wind and marine elements. Full sun with zero shade increases heat and dehydration risk.
Crowd Level: Solitude; very limited access due to permit, ranger, and boat requirements
Peak Crowd Times: Access limited by boat schedules and ranger availability; no specific peak times
Best Time To Visit: Coordinate with NPS ranger availability; the island must have active staff on-site. Clear weather windows typically May-September. Arrive early at boat departure point; ranger schedule controls your access.
Tips Advice: Confirm island is open (NPS staff presence varies) before committing to boat\n
Carry minimum 2-3 liters water; dehydration is the real killer over 16 miles\n
High-SPF sunscreen and protective clothing; zero shade on island\n
Trekking poles mandatory; uneven terrain hammers knees on descent\n
Plan 30+ minutes for wildlife viewing; don't rush past the colonies\n
Stay on marked trails; former bombing range—UXO risk is real

Family Friendly Notes: Not family-friendly for young children or inexperienced hikers. Strenuous distance, mandatory ranger requirement, and federal UXO restrictions mean this is serious backcountry—not a recreational hike.
