We stayed at the upper campground at Scorpion Anchorage on the Eastern part of Santa Cruz Island. We almost stayed 2 nights because the Santa Ana winds were so bad the boat couldn't come over in the morning. Luckily they died down in the afternoon so we could get "rescued."
We hiked about 10 miles of trails around Scorpion Anchorage, and the weather (except the wind) was great both days!
