We stayed at the tent walk in sites (D25) The sites are close together but otherwise, well maintained. There are two wheelbarrows usually loated near the bathroom to help move gear as many of the sites are walk in.

Back behind D25 area there is a path that leads to the RV sites (which are even closer together). On that path is a mound o free firewood to take an armfull each day. But I would bring firewood as a backup as it sometimes is empty.

No showers at the campground, but there is a store just up the road towards Southwest Harbor. They have hot showers *bring quarters) and most camping items you may have forgotten or broken.

The seawall area also gets very good sunrise and sunset views out on the rocks. There are a bunch of day use sites out there with fire rings, so you can cook on the wall at sunset.

There's also a lot of good hiking you can get to on that side of the island without going all the way back to the main park.

You can buy your park pass at the ranger station when you check in so you don't need to go to the main gate or visitor center to get one.
