About West Thompson Lake Campground
Overview
West Thompson Lake Campground is located near the wooded shoreline of its namesake lake in northeastern Connecticut. The natural setting surrounding West Thompson Lake can be enjoyed year round. Visitors come to the lake for camping, fishing, boating, kayaking and hiking.
Recreation
West Thompson Lake provides great boating, kayaking, canoeing and fishing opportunities. It has an excellent population of warm-water fish, including bass and small panfish. A boat ramp is located near the campground for easy access to the water. The Thompson Section of the Quinebaug River Water Trail offers a leisurely three-hour outing for paddlers who are comfortable with moving water. The trail has no rapids or portages and meanders through extensive wildlife habitats. An 18-hole disc golf course is located on the lakeshore and is free to the public. This challenging course is known for its long drives and scenic views of the lake and dam.
Facilities
The entrance gate to the campground is closed from 9pm - 8am.
The campground offers 11 campsites with electric and water hookups, 11 basic sites without hookups and two Adirondack lean-to shelters. Amenities include accessible flush toilets and showers, and a dump station. An amphitheater, playground, basketball court, and interpretive trails are located on-site.
Natural Features
The campground is nestled in a forest of Eastern white pine, Northern red oak and Shagbark hickory. Shade is abundant throughout the campground, and autumn leaves put on a beautiful show.
An overlook at the dam offers pleasing panoramic views for sightseers and photographers.

FAQ
How do I get a reservation at West Thompson Lake Campground?
Campsite Sniper's current snapshot shows none of the 312 tracked site-nights open for online reservation at West Thompson Lake Campground. That can mean dates are reserved, closed, not yet released, or offered first-come, first-served rather than online. Pick a site on the map to see its calendar, or set a free Campsite Sniper alert. You complete the reservation yourself on Recreation.gov.
Does Campsite Sniper book this campground for me?
No. Campsite Sniper sends alerts and direct Recreation.gov links. It never books, pays for, holds, hoards, or resells reservations.
How current is this availability data?
Campsite Sniper re-checks public Recreation.gov availability for this facility every hour and republishes whenever anything changes. This facility's data last changed at Sep 18, 2026 16:19 UTC; an older timestamp means nothing has changed since that time, not that checking stopped. Always confirm final availability on Recreation.gov when you book.
Which sites at West Thompson Lake Campground fit a 35-foot RV?
11 of the 24 sites that support RV analysis have a recorded maximum of 35 ft or more; the longest recorded is 40 ft. 22 of those 24 sites have a recorded maximum length and 2 do not; they are not counted as fitting.
