Gillette Castle State Park

East Haddam, CT

Each year, a whopping 300,000 visitors flock to enigmatic William Gillette’s inspired mansion perched high above the Connecticut River to immerse themselves in history, architecture, and nature. Tour the modern medieval stone castle, hike the wooded grounds along the former bed of a miniature train, revel in the spectacular river views, or pitch a tent in one of the few river camping spots in Connecticut, and discover why so many are drawn to the stunning park.  

Built in 1914 by William Hooker Gillette, the actor, director, and playwright most famous for his portrayal of Sherlock Holmes, the ornate, 14,000-square-foot stone fortress sits 200 feet over the Connecticut River atop the most southerly hill in a chain known as the Seven Sisters and is surrounded by 184-acres of gorgeous Connecticut woodlands. After his passing, the State of Connecticut purchased the castle and adjoining acreage to create a state park. 

William Gillette gave specific directions in his will that the property did not fall into the hands "of some blithering saphead who has no conception of where he is or with what surrounded."

Gillette's artistic influence is no less visible outside the mansion on the park grounds. Many trails follow the former path of the actor’s three-mile-long, quarter-scale, narrow-gauge railroad that he used to ferry his friends around the estate. Gillette's own walking paths were constructed with near-vertical steps, stone-arch bridges, and wooded trestles spanning up to forty feet.

Train Trail (Purple Blaze) to Blue Trail (Blue Blaze) 

  • 1.5-mile trail along converted railroad path and former driveway 
  • Level of difficulty: Easy to moderate
  • Wind through the park along the purple trail, the original path of Gillette’s miniature railroad, over footbridges and trestles and through an abandoned 75-foot train tunnel. A word of warning – the tunnel is very dark and, depending on your idea of fun, either exhilarating or a little creepy. Then link up with the blue trail which leads to the home of Gillette’s closest confidant, Yukitaka Osaki, and the wreckage of the Aunt Polly, Gillette’s houseboat that was destroyed by fire in 1932 (best viewing is during low tide).  





Did you ever wonder what the Connecticut landscape looked like a century ago? Check out “Viewpoints”, a joint project of the Connecticut Commission on the Arts, the Connecticut Art Trail, and the Department of Energy and Environmental Protection.

Outdoor exhibits reproduce works of art painted in the 19th Century, with information about the artist and the location. Visit the Connecticut Art Trail website for a preview, and look for the Viewpoint exhibits when you visit the Chester-Hadlyme ferry landing area of Gillette Castle State Park and spot where William Chadwick found inspiration for “Connecticut River: View from Ely’s Ferry Road”.


William Gillette designed his 24-room castle and most of its furnishings personally. Everything from the built-in couches, a movable table on tracks, and hand-hewn southern white oak woodwork including carved wood light switches and forty-seven distinctly designed doors, reflects his singular imagination and creative genius. Built of local fieldstone and steel framework, it took twenty men five years (1914-1919), just to complete the main structure.

Along with the mansion itself, the park is home to a trove of historical treasures including the wreckage of Aunt Polly, Gillette’s houseboat destroyed by fire and one of two underwater preserves in the state.
