Campgrounds and RV parks near Castleton Four Corners, VT

Lake Bomoseen is the region's centerpiece for swimming, boating, and warm-water fishing, with species including largemouth bass, yellow perch, and northern pike. Bomoseen State Park has a day-use beach, boat rentals, and hiking trails through former slate-quarry country, including the self-guided Slate History Trail past remnants of the historic West Castleton slate complex. Hubbardton Battlefield, in nearby Hubbardton, marks the only Revolutionary War battle fought on Vermont soil and has a small interpretive center. The Slate Valley Museum, across the state line in Granville, New York, covers the region's quarrying history. Paddlers use quieter waters at Half Moon Pond, where motors are not allowed, and Lake St Catherine, both suited to canoes and kayaks. The Delaware and Hudson Rail Trail runs south from Castleton toward Poultney for cycling and walking.

The Vermont state parks in the Castleton area operate on a seasonal schedule. Bomoseen State Park and Lake St Catherine State Park generally run from the Friday of Memorial Day weekend through Labor Day weekend, while Half Moon Pond State Park stays open a bit longer, through the second Monday in October. Outside those dates, state park campgrounds are closed and gates are locked, though day-use access on foot is often still permitted. Summer is peak season. July and August bring the warmest lake temperatures and the busiest weekends, and lakeside sites at Bomoseen fill early. June and early September are quieter alternatives with comparable weather and fewer bugs than late spring. Fall foliage in the Taconic Mountains typically peaks from late September into early October, and Half Moon Pond books out well ahead of leaf-peeper weekends. Winter camping is not available at the state parks; private options may offer limited off-season hookups but should be confirmed directly with the operator.

Vermont state park campgrounds in this region offer tent and RV sites without hookups, along with lean-tos and a few cabins, plus shared restrooms with flush toilets, token-operated hot showers, and an on-site dump station. Sites are wooded or grassy and can be uneven, and some access roads are narrow, so travelers with larger Class A or fifth-wheel rigs should check length limits before booking. Lake Bomoseen KOA Holiday and Smoke Rise Campground provide the full-hookup sites, longer pull-throughs, and amenities such as Wi-Fi and laundry that are not available at the state parks. Cell coverage is patchy in the hills around Half Moon Pond and parts of Lake St Catherine. Black flies and mosquitoes are heaviest from late May into June.
