Cascade Brook Trail

Overview

This is a water-lover’s walk: a compact loop stitching together The Basin, Kinsman Falls, and the riffly, boulder-choked Cascade Brook. Expect granite slides, punchy little cascades, and clear pools you’ll want to linger at. The popular loop is about 2.9 miles total with roughly 656 feet of gain—short, but not a cakewalk thanks to rock-hopping and roots.

Route at a glance

Park at The Basin and follow the pedestrian tunnel to the start. Head up the Basin–Cascades Trail past The Basin (a classic glacial pothole just a short walk from the lot) toward Kinsman Falls (about 0.5 mile). Continue to the junction and turn onto Cascade Brook Trail, then descend to meet the Pemi Trail and follow it left back to The Basin to complete the loop. If you’re feeling good, you can extend upstream on Cascade Brook Trail to serene Lonesome Lake for a longer outing.

Trail feel and scenery

The draw here is water: a string of cascades, mossy ledges, and inviting pools. Kinsman Falls punches into a deep basin, and upstream/outbound you’ll find more slides and small waterfalls. The Basin itself—polished smooth by ancient meltwater—makes a quick, must-see detour right at the start or end.

Conditions to expect

Footing is rocky, rooty, and slick near spray zones. There are unbridged crossings on Cascade Brook; depending on flow, you may get wet feet or decide to turn around. Some junctions aren’t obvious; having a downloaded map helps. This loop typically takes 1.5–2 hours at a relaxed pace.

Best time to hike

Late spring through fall is prime. After heavy rain or during snowmelt, crossings can run high—save it for lower water days. Early mornings beat the crowds around The Basin and Kinsman Falls; afternoons bring warmer light for photography and a shot at dipping feet in the pools. Autumn colors make the brook corridor pop.

Tips and add‑ons

Wear sturdy footwear with good traction and supervise kids and dogs near edges. Bring your own water—don’t count on potable water at the Basin trailhead. Dogs are allowed on park trails when leashed or under close voice control, but not in the Flume Gorge or campgrounds. For more mileage, continue to Lonesome Lake via Cascade Brook and loop the shore before returning; for a quick sampler, simply visit The Basin, Kinsman Falls, and Rocky Glen Falls as an out-and-back.
