Insider Tips
🏰 Local Knowledge
- Passport to the Parks = free access: If your vehicle has CT plates, you already have free unlimited access to all 110 parks — funded by a small surcharge on your vehicle registration. The program is unique in the nation. Non-residents pay $7–$22 per visit.
- Hammonasset 7-night cabin rule: The 8 shoreline cabins require a Sunday-to-Sunday 7-night minimum during peak season. Book the day the 11-month ReserveAmerica window opens — they sell out instantly. Cabins are rustic (electric, beds, no kitchen/bath). Pack your own meals and cooking gear.
- Gillette Castle canoe camping: One of New England’s most unusual camping experiences — paddle to river-access-only sites below the castle. No vehicle access, no fires, pit toilets only. True wilderness isolation minutes from civilization. Check tide schedules and current strength.
- Devil’s Hopyard no-water warning: The 21 wooded campsites have no potable water — bring everything you need. Many visitors don’t realize this until arrival. Beautiful Chapman Falls makes it worth the planning.
- Kent Falls + Sleeping Giant day trip: These two parks make a perfect day combination — start with the 250-ft Kent Falls cascade in the morning, then drive south for the Sleeping Giant’s Tower Trail in the afternoon. Pack a picnic for the stone tower summit.
- Dinosaur State Park trackway: 200-million-year-old dinosaur tracks under a geodesic dome — one of the largest in-situ trackways in North America. Kids can make fossil castings in the outdoor area (bring 10 lbs of plaster of Paris, ¼ cup cooking oil, and a 5-quart bucket).
