Chaplin Natchaug River Swimming Spots

About Diana's Pool on the Natchaug River

Tucked into the quiet woodlands of eastern Connecticut near the small town of Chaplin, Diana's Pool is one of those rare places that feels like a secret even when you already know about it. Fed by the gentle but purposeful flow of the Natchaug River, this beloved swimming hole has drawn locals, families, and UConn students for generations — a testament to the kind of simple, unhurried beauty that keeps people coming back year after year.

The Setting and Landscape

The star of the show is an elegant triple-tiered waterfall that carves an 'S'-shaped path through ancient, smoothed bedrock before spilling into the wide, clear pool below. The sculpted rock formations surrounding the water have been shaped over centuries into natural ledges and hollows that invite exploration. In summer, the canopy closes overhead in a thick ceiling of green, dappling sunlight across the current and keeping the air noticeably cooler than the surrounding countryside. Come autumn, the same trees ignite in crimson, amber, and gold — making this one of the more photogenic swimming spots in the state even after the season for a dip has passed. Birdwatchers and wildlife enthusiasts will find the riparian corridor alive with activity; keep your eyes on the banks and sky for herons, kingfishers, and other woodland creatures drawn to the river's edge.

The Swimming Experience

The water at Diana's Pool is famously clear, with the characteristic cool crispness of a Connecticut river fed by shaded woodland streams. The sculpted rock walls and natural basin create a swimming hole with real depth and character — you can wade in from the shallower edges or ease in from the surrounding ledges. The waterfall itself adds a constant, soothing soundtrack to your visit and provides a natural focal point for swimmers and sunbathers alike. That said, wet rocks near the falls and swift currents demand genuine respect; water shoes with grip and a careful eye on conditions are strongly recommended, especially after rain. There are no lifeguards or safety personnel on site, so swimming here means taking personal responsibility for your own safety and the safety of those with you.

What to Know Before You Go

Diana's Pool is free to visit and requires no fee. Facilities are nonexistent — no restrooms, no changing areas, no concessions — so arrive prepared with everything you need for the day. The access trail is short and suitable for most fitness levels, though the path can be uneven. Sanction status for swimming varies, so it's worth checking local conditions and any posted signage when you arrive. The site does not offer camping, but Mashamoquet Brook State Park to the northeast provides a solid base camp if you're planning an overnight stay in the region.

Plan Your Visit: Diana's Pool sits within easy reach of Chaplin, Willimantic, and Hartford, making it a natural day-trip destination from much of central and eastern Connecticut. Summer is the prime season for swimming, though spring brings blooming wildflowers along the river corridor and fall rewards visitors with some of the region's finest foliage color. Pack a picnic, bring a towel, and leave no trace — this spot endures because the people who love it take care of it.
