All About the Connecticut River
Wilgus State Park is the first Vermont state park to open each spring, well before Memorial Day each year. While it's still pretty cold for camping in Vermont in early May, you can get a jump start on the season by renting one of the four camping cabins. I'll admit that I haven't stayed in one of the Wilgus cabins, but they are pretty much the same all over Vermont - nothing fancy - just four solid walls, bunk beds, and a small table.
Usually when we stay at Wilgus State Park, we rent a lean-to or stay in site #16, which is the very last tent site, and the most private. All sites have a great view of the river, but I won't go so far as to call them waterfront as there is a bank covered with lush foliage between the sites and the water. There is also a short trail that runs between the campsites and the water - a great place to watch the sunrise!
The best part about camping here is getting out on the water. You can rent kayaks and canoes, and the river moves slowly enough to paddle up stream. There is also a shuttle service run by Great River Outfitters upstream in Windsor. If you make reservations, the come to the park (I think on Wednesdays and Fridays), and they will pick you up in the morning, drive you up river to Windsor, outfit you with a canoe or kayak, and let you paddle back to the park. Later in the evening they will come back and pick up the boats. If you choose this option, be sure to stop at Artisan Park, right on the river and have lunch at Harpoon Brewery.
The campground is really small (under 25 sites) and super quiet. Restrooms are clean. There is a short hiking trail, which is just okay - no views or anything. The ranger has been there for years and is an expert fisherman. He's got lots of tips if you ask. For good hiking, be sure to check out Mt. Ascutney, which is just a few miles away.
