Climbers scale a few of the rock formations where conditions and park rules permit. The Channel Islands bask in an agreeable climate most of the time, although fog occasionally sets in, and the higher altitudes can get chilly. In winter, the days are mild and the nights freezing. Ideally, one visits in spring or fall, when the highs average 85 degrees and the lows 50. Those planning to spend the night, or nights, on any of the five islands must bring their own provisions, including water.
Campgrounds are primitive, restrooms basic and food sellers nonexistent.
There are only 79 campsites, divided amongst the islands. Permits and reservations are required. Those preferring to sleep in a tent or under the stars will find nine campgrounds with tables, fireplaces and toilets. No hookups for RVs. Bring your own firewood, as all park vegetation is protected.
