Quite a few trees around the campground, if I recall it well. Pricing arrangements are strange though. Did not have my attorney with me to interpret their policies, when discussing prices over the phone. Last time we camped there, the price was per pad (they are rather huge, I'd say.) Recently Sidney campground was taken over by Gulf Islands National Park Reserve. In any case we should be prepared to see someone collecting the fees. So, anyone else interested in Sidney Island? I'm.
