About Waterman Gap

Waterman Gap Trail Camp is one of four backcountry trail camps still operating in the Santa Cruz Mountains state parks, alongside Castle Rock, Waterman Gap and Butano or Slate Creek. All trail camps in Big Basin Redwoods State Park remain closed due to extensive fire damage from the CZU August Lightning Complex fires, which is why these four carry the whole of the Bay Area's state park backpacking demand. ReserveCalifornia lists six sites here. Waterman Gap has no first-come pool. Castle Rock Trail Camp is the only camp in the system that keeps sites available first-come, and those are registered in person at the Robert C. Kirkwood Parking Lot on Highway 35. Everything at Waterman Gap goes through the request form. Booking does not go through ReserveCalifornia. Submit a Backcountry Trail Camp Request Form online up to 60 days in advance. Staff process requests Monday through Friday from 1 p.m. to 5 p.m. An approved request is held only until 5 p.m. the following business day pending payment, which is taken by phone on (831) 338-8867, and the permit is emailed once paid. Sending a request is not a reservation - it becomes one when it is paid. Changes and cancellations must be made a full 48 hours in advance on the same number. Fees are $15 per site per night with a maximum of six people per site, plus an $8 non-refundable reservation fee. You may reserve up to two campsites per reservation. For groups of 13 or more the non-refundable reservation fee is a flat $25 no matter how many campsites are booked, and group reservations are allowed Sunday through Thursday only, not on weekends. The camps are primitive: bring your own water, and treat any surface water before drinking it.

Waterman Gap is the next trail camp west of Castle Rock along the Skyline-to-the-Sea Trail, which makes it the second night of the classic Bay Area two-night traverse - or a quieter first night than Castle Rock for anyone who wants six sites instead of twenty. It has no first-come pool, so unlike Castle Rock, everything here is booked in advance through the request form.

The Experience

Deeper into the woods than the Castle Rock ridge and correspondingly quieter. Six sites in redwood and mixed forest, no phone signal, and the trail closing at sunset - which means that by dark the only people out here are the ones with permits.

Waterman Gap sits along the Skyline-to-the-Sea Trail in Castle Rock State Park, west of Castle Rock Trail Camp. ReserveCalifornia lists six sites. The Skyline-to-the-Sea Trail is open from Castle Rock State Park to the Big Basin Redwoods day-use area, so this camp is on the walkable section - all of the trail camps inside Big Basin itself remain closed due to extensive fire damage. Overnight parking for backpackers is only in designated trailhead parking lots.

Overnight parking for backpackers is only in designated trailhead parking lots - do not park along highways or in undesignated areas

Hikers must be off trails by sunset; arriving after sunset means you will not be permitted to start your trip

Gear & Preparation

Required Gear

  • All your drinking water. State Parks says the trail camps are primitive and to bring your own; surface water must be treated before drinking
  • A backpacking stove, which is permitted in all trail camps except in cases of extreme fire danger
  • A headlamp - you must be off the trails by sunset, so camp chores happen after dark
  • Rain gear through the wet season, which in the Santa Cruz Mountains is most of the winter
  • Tree straps if you are hanging a hammock, and never on a redwood

Hazards & Safety

No mobile coverage. In an emergency, call 911 from a pay phone near a ranger station or a call box on Highway 1 or Highway 9 and a ranger will be dispatched

A sunset trail deadline that is enforced at the trailhead - late arrivals are not permitted to start

Fire danger, which closes even the one permitted fire location in the system

Poison oak throughout the Santa Cruz Mountains understory

Creek water that must be treated if you use it at all

Best Time to Visit

Spring and autumn. Winter is the rainy season here, which is when the creeks run and the camps empty out, but it is also short days against a sunset trail deadline. Summer is dry, busy and under fire restrictions - and unlike Castle Rock, Waterman Gap has no fire rings even in the rainy season.

Pro Tips

1

Submit the request form the day your dates come inside 60 days. A request is not a reservation until you pay by phone.

2

Requests are only processed weekdays between 1 p.m. and 5 p.m., so anything sent on a Friday evening waits for Monday.

3

Plan to reach camp well before sunset. Hikers must be off trails by sunset and a late arrival is turned back at the trailhead.

4

Carry all your water and a way to treat creek water as a backup.

5

Do not count on a phone. State Parks says it is unlikely your mobile will have coverage in the backcountry.

6

Groups of 13 or more can only book Sunday through Thursday, so plan a midweek trip rather than fighting for a Saturday.

7

Changes and cancellations need a full 48 hours notice on (831) 338-8867, which is also when someone else's cancellation appears.
