We stayed for a week at one of the hike in sites, specifically the one furthest from the car/RV camping area. The sites are newer looking with nice tent pads, a bear box, and a picnic table. It’s a few minutes’ walk from the campsite to an immaculately clean vault toilet. The bathroom for the car camping area with running water, the dishwashing area, and WiFi were maybe a 2 minute walk beyond that. We had such an amazing time and spent the majority of our time on the Schoodic peninsula. We only went to the main part of the park twice the whole week. Plenty of trails, scenic views, and things to do just in Schoodic Woods. It’s also WAY less crowded than the main part of the park. Winter Harbor has a few restaurants and little shops but no big grocery/big box stores that I saw so stop on the way if you need stuff. The rangers were all very nice and helpful. I can’t wait to go back!
