Channel Islands in April: what the park service says
April is nesting time. West Anacapa and Santa Barbara hold the only brown pelican breeding colonies in the western United States, and on Santa Barbara Island the nesting area is closed and trails shut while birds sit on eggs. The Anacapa campground listing gives gull nesting season as April to August, so expect loud, defensive birds around camp; the site is half a mile from the landing, up 157 stairs, with vault toilets and no drinking water. Every campground needs a reservation, which recreation.gov opens up to six months ahead. Paddlers should still plan for east or Santa Ana winds, which the park says are most common from September through April.
