Selden Neck State Park occupies 607 acres along the Connecticut River in Lyme, New London County, making it one of the state’s most distinctive parks — accessible only by water. This river island park sits between the main channel and the eastern shore, creating a secluded wilderness experience remarkably close to civilization.

What sets Selden Neck apart is its boat-in-only access. There are no roads, no parking lots, and no crowds. Paddlers and boaters arrive along the Connecticut River, one of the most scenic waterways in New England, and find themselves on a densely wooded island with towering hardwoods, rocky bluffs, and quiet shoreline trails. The 4.6-star rating from visitors reflects the kind of place that rewards the effort it takes to get there.

Hiking trails wind through the interior forest and along the riverbank, offering views of osprey, bald eagles, and great blue herons that nest along the corridor. Fishing is productive in the surrounding waters, with bass, perch, and shad running seasonally. Kayaking and canoeing are the primary ways visitors explore the island’s coves and inlets.

The park operates primitive campsites — ideal for paddlers looking to turn a day trip into an overnight adventure. Expect no hookups or facilities beyond basic fire rings and pit toilets. Bring everything you need and pack everything out.

Late spring through early fall is the sweet spot for visiting. Summer weekends see the most river traffic, so midweek trips offer the most solitude. Come prepared for mosquitoes near the water and you’ll have a memorable Connecticut River experience.
