State Park · Connecticut
Gillette Castle State Park
An eccentric stone mansion above the Connecticut River, with seasonal castle tours, old narrow-gauge railroad trails, river views, and a ferry crossing nearby.
Field briefing
Gillette Castle State Park starts with access, not mileage.
Before you go
Gillette Castle is a sightseeing and easy-walking park rather than a hiking destination, built around the strange, hand-crafted stone mansion of stage actor William Gillette.
The grounds and gentle railroad trails are free and open year-round, while the castle itself runs on a seasonal schedule, roughly May into late September, with limited daily tour tickets that are worth pre-booking. There is no camping here, so plan it as a day trip.

Top things to do
Gillette Castle tour
Tour the 24-room stone mansion built by actor William Gillette, full of hand-carved woodwork, hidden mirrors, and custom puzzle locks. Daily tour tickets are limited, so pre-booking is strongly recommended in season.
Railroad trails
Walk the old narrow-gauge railroad bed that Gillette built across his estate, a gentle network past ponds, stone arch bridges, and river overlooks.
Connecticut River overlooks and the ferry
Take in the cliff-top river views, then ride the seasonal Chester-Hadlyme ferry below the park, one of the oldest continuously operating ferries in the country.
Anchor the day around Gillette Castle tour
Lock the boat, ferry, tide, or water access first, then fit the route list around that schedule. For one day in Gillette Castle State Park, make Gillette Castle tour the non-negotiable, add Railroad trails only if the first stop runs clean, and keep Connecticut River overlooks and the ferry as the flexible finish.

Where to stay
There is no camping at Gillette Castle, so it works best as a day stop. Nearby East Haddam, Chester, and Old Lyme have inns and restaurants, and the lower Connecticut River valley pairs well with a longer shoreline trip. For campers, Hammonasset Beach State Park down on the coast is the nearest state-run campground.
