Channel Islands' Campgrounds, Counted

The park table first:

Facility	Confirmed openings	Distinct campsites	Median survival
Santa Cruz Island Scorpion	240	31	25h 20m (n=80)
Anacapa Island	17	6	withheld — too few completed cycles
Santa Rosa Island	23	9	withheld — too few completed cycles
Santa Barbara Island	3	3	withheld — too few completed cycles
Santa Cruz Island Del Norte Backcountry	20	4	withheld — too few completed cycles

The frame is the park's geography. Channel Islands' campgrounds sit on islands reached only by boat — the park concessioner Island Packers from Ventura Harbor, or private boat — and Recreation.gov's Scorpion listing is blunt about the order of operations: visitors are required to arrange boat transportation to the island before reserving a campsite, camping reservations are required before arriving, and there are no walk-ups. Scorpion Canyon Campground, on the largest island, holds 31 sites in all — 25 individual sites and six group sites — and can be reserved up to six months ahead. Our directory, built from the Recreation.gov RIDB export, lists the same 31 for Scorpion, 16 for Anacapa, 16 for Santa Rosa, 21 for Santa Barbara and 9 for Del Norte Backcountry. Our scanner watches all five facilities: the park's reservable island system as our registry defines it.

The farthest horizon in the log

Lead time is where the islands stand alone. The park-wide median lead of 21 days — 24 at Scorpion — is roughly four times the mainland pattern, and there is no release cliff inside it (a single opening at exactly 14 days park-wide). The flow is cancellations, but cancellations from a different kind of trip: a Channel Islands night is the second half of a two-part booking, campsite plus boat, made weeks ahead because the boat schedule demands it. When the trip moves, it moves early. This blog has measured the far-ahead effect before — openings detected a month out live longer than last-minute ones — and the islands are that effect at full strength, produced by geography rather than by a release calendar like Kipahulu's.

Scorpion: the whole campground, surfaced

Scorpion is the park's deep water: 240 openings, 79.2% of the park's flow, from 31 distinct campsites — every campsite in its directory listing. In eleven days, the entire campground's inventory has passed through the cancellation market at least once. Its openings survive a median 25h 20m (n=80), the slow clock of far-ahead flow: a Scorpion opening is a planner's decision, taken over a day, not a sprinter's. The smaller islands are thinner in every dimension — Santa Rosa 23 openings, Del Norte 20, Anacapa 17, Santa Barbara 3 — and this post prints their counts exactly and their survival medians not at all, because their completed cycles (n=10, 9, 5, 1) sit under the twenty this blog requires. That restraint is the method working as intended: the islands' small campgrounds will get their numbers when the log has earned them.

What this means for a hunter

Work a month ahead, and bring the boat into the plan from the first minute. The openings you want surface a median 24 days out at Scorpion, so a watch set for 'sometime next month' is fishing the right water here — the opposite of the last-minute desert game. At a 25h 20m median survival, you usually have a day to line up the Island Packers sailing that matches your campsite dates; but line it up you must, because Recreation.gov requires the boat to be arranged before the campsite is reserved, and a won campsite with no sailing to reach it is a story, not a trip. Treat the smaller islands as long-game watches: their openings are real but rare in this log, and each one is worth answering the day it fires.

The limits, plainly

The window is eleven days in the islands' cool, rough-water shoulder season; November-through-May sailings are weather-sensitive in a way our log cannot see, and nothing here describes the summer peak. Four of the five facilities have counts too small for survival claims, and this post makes none for them. San Miguel Island's campground is not in our watch registry, so 'the park's system' here means the five watched facilities, named in the table. What survives the caveats is the horizon: 303 verified openings, detected further ahead than anywhere else we measure, in the one park where the trip has to be planned before it can be cancelled.
