We camped at two harbors in May of 2015 and had a lot of fun. We took the ferry to two harbors and walked up all of our gear to the site. It is a bit of a walk if you aren't packed correctly (we brought a cooler and it was a bit rough getting it up there). 

The water in the harbor is super clear. We kayaked around the area and loved it. At night we had deer walking directly through our site as we were eating dinner (seriously on a few feet away). They didn't both anyone and were really cool to watch. 

The price is steep especially counting in the ferry, but it was a lot of fun and I'd do it again. 

The bar near the harbor was a nice plus as well. Getting a beer after kayaking during a  camping trip was fun.
