About
A large Thousand Islands campground on the St. Lawrence River, with 414 tent/RV campsites plus cabins and cottages. One loop offers electric hookups, another offers full hookups including sewer; most other loops have no hookups. Bathhouses with hot showers, dump stations, a camp store, laundry, marina, and beach are all on site. Up to 2 leashed pets are allowed in most areas (not in cottages) with proof of current rabies vaccination.
Fees
Standard state park camping rates apply: about $17/night base rate plus a $7.25 reservation fee, plus surcharges of $7-15/night depending on hookup type in loops that offer them. A $5/night non-resident surcharge applies to out-of-state campers. Confirm current pricing and hookup availability when you book.
