First off the campground is nice. There are RV sites with hook ups in a more open field type area that have a great view of the water, though are a bit packed in. The non hookup sites on the western end of the campground are more of the campground feel being more tucked back in the trees and offer a bit more privacy. Access with RVs can be tricky though. Larger rigs needs to stick with the hook up sites to be safe. It does get crowded in the warmer months, it’s a popular place for a reason. The hiking trails around the park offer great views, interesting history with the WW2 bunkers and low tide brings out some pretty awesome tide pooling along the tongue. Reservations change during the year so check for the time you are wanting to visit. Cell service can be had, our AT&T worked, just make sure you are good with international roaming with Canada since you will at some point be on a tower there.
