The 4-mile round-trip from Prisoner's Harbor exposes you to true island terrain—relentless sun, coastal wind, and solitude. Moderate to strenuous difficulty with zero shade means this demands fitness baseline and exposure tolerance. Access is non-negotiable: Island Packers' guided shuttle or your own boat with a valid landing permit. Payoff: unobstructed coastal vistas of The Nature Conservancy's protected island property.
Moderate to strenuous
Unobstructed Pacific coastal vistas from The Nature Conservancy's protected island property. Exposed island coastline and dramatic seascapes.
• Island Packers schedule is your master constraint—book weeks ahead and confirm departure time the day before • Sea state changes fast; morning departures are more reliable than afternoon runs • The 4 miles will feel longer in coastal wind; pace accordingly • Bring extra water; the sun is relentless on exposed island terrain and dehydration happens fast • Scout your descent route before dark; waves can kick up suddenly and block return paths • This is full self-sufficiency: no resupply, no shelter, no backup. Plan for independence.
Moderate-strenuous terrain, exposed conditions, and boat logistics make this unsuitable for young children. Teens with hiking experience and strong swimmers may attempt with experienced adult supervision and proper water safety gear.
Hikers report that this trail delivers exposure and grit in one package. The moderate-to-strenuous terrain is compounded by island logistics—you're at the mercy of boat schedules and sea state, which can turn a planned day trip into a rescheduled adventure. Those who complete it praise the coastal solitude and unobstructed Pacific views as their reward.
Island Packers passengers travel with staff—no separate permit required. Private boaters must secure a valid landing permit from The Nature Conservancy for coastal property access.
Island Packers boat concessioner operates daily shuttle service from Prisoner's Harbor. Alternatively, private boaters must obtain a valid landing permit from The Nature Conservancy for access to coastal property.
Island terrain exposes hikers to intense sun and relentless coastal wind. Boat access is weather-dependent; trip cancellations occur if sea conditions are unsafe. Moderate-strenuous difficulty requires fitness baseline. Injury response time is slow—help requires boat evacuation.

Only if you have your own boat and a valid landing permit from The Nature Conservancy. This is a boat-only trail; there is no road access or walk-up option.
The NPS rates it moderate-to-strenuous. That means steady climbing and elevation work with exposure tolerance required. If you can comfortably hike 4+ miles with elevation on mainland trails, you have a baseline shot. Island exposure and persistent wind make it feel harder than the distance suggests.
Your hike won't happen. Island Packers won't run if sea conditions are unsafe for the vessel. Your deposit typically transfers to a future date, but refunds are rare. Book flexible dates and have a backup plan.
Yes. Bring 2+ liters of water (no resupply), sun protection (hat, sunscreen, light long sleeves), sturdy boots for uneven coastal rock, and weather layers. The island is windy and can be cold despite coastal heat. Bring trekking poles for exposed terrain.
No. Boat access severely limits traffic, so you'll see few hikers. This solitude is the appeal—and the reality: if you get injured, help isn't instant and requires boat evacuation.
Dogs are not permitted on national park trails except registered service animals.
This is part of the commitment. Confirm your Island Packers departure time the day before. Rough seas can delay or cancel runs. Budget time for the boat ride in both directions and arrive at the harbor early for check-in.
