We stayed at Green Mountain for three nights. We picked a site without really knowing the layout of the park. Our site was #4 and it was easy to park. We had a deck at our site which was a but problematic due to our steps folding out, it took some finagling and leveling to get it to where we could close our door. The whole camper ground is nicely taken care of with some site far up on some hills, so if you stay, ask about where the site is and how easy it is to get into, some looked wild! The restrooms are very primitive, remind me of old church camp bathrooms I used to go to haha. There are some hiking trails that are accessible from the park. You can pick up a map from the front office. It is mountainous so be aware the trails are quite steep and strenuous but not super long. We did hike up to an overlook area and the fall colors were amazing. There is a gate entry card that costs $15 outside of the Thousand Trails network but when you check out they return the $15 if you return the card. Overall, this was a decent Campground.
