Point Bennett - 16mi Strenuous Island Hike

Q: How hard is 16 miles strenuous?

Q: What kills hikers on this trail?

Dehydration (carry extra water), sun exposure (protective gear mandatory), and tired legs on descent (trekking poles help).

Q: When is the island closed?

Whenever NPS staff aren't on-site. Confirm at least a week prior by calling the park visitor center.

Overview

About This Trail

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.

Insider Tips

• Book Island Packers or Channel Islands Aviation 2-3 weeks out; they control your schedule\n• Ranger accompaniment starts at ranger station; you cannot hike beyond alone\n• Bring a headlamp even in daytime; you might hike back after sunset\n• Seal colonies appear around Mile 12; keep camera ready from Mile 10 onward\n• Wildlife is unpredictable; patience and silence give best observations

Hiking Tips

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 Info

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.

What Hikers Say

Hikers seeking serious wildlife encounters call this one of the park's most engaging activities. The 16-mile strenuous distance and mandatory ranger requirement ensure solitude and commitment. Few reach this trail; fewer still without proper preparation.
