Best time to visit Stillwater State Park

Late June through August offers the warmest weather, swimmable lake temperatures, and reliably open campground roads, making it the peak window for RV travelers. Early June and September are quieter shoulder periods with cooler nights and fewer bugs, and late September into early October can deliver strong fall foliage in the Green Mountains. The park is a seasonal operation and is closed in winter, so RVers should plan trips between mid-May and mid-October.
