The remote campsites at the norther end or Umbagog Lake are wonderful. This trip consisted of my family of five with three kids (ages 5-13), our dog, and friends. We put our boats in at the National Wildlife Refuge and paddled in on Bear Brook. The paddle was just around 2.5 miles and calm flat water. Just perfect for our kids, and far enough feel remote but easy enough for our kids. The sites have a pit toilet and fire ring. While there were plenty of eagles, loons, and fish we only saw two other boats the entire weekend.
We biked to this park from Burlington via the Island Line Trail. It was a super trip. The lakeside lean-to was awesome.
This park's got amazing trails for hiking and mountain biking, a resivoir for boating and swimming, and a ghost town to explore.
Since this campground is withing Burlington city limits it is a bit cramped and can get crowded. However it's location makes it convenient too. Plus it's right on Lake Champlain with great beach access.
Wonderful lean-tos and campsites on an island in Lake Champlain. Great Experience!
