About Smarts Brook

Smarts Brook offers a refreshing cold spring experience nestled at the base of the White Mountain National Forest in New Hampshire. This primitive spot features a lovely cascading brook that flows into a deep, clear pool, inviting you to cool off in crisp, pure water surrounded by lush forest. It’s a tranquil retreat among the hot springs in New Hampshire that highlights the state’s diverse natural swimming holes.

Getting There

To reach Smarts Brook, start at the dam in the center of Campton and head north on Route 49 for 3.9 miles. The trailhead parking is limited and located on the right side of the road. From there, you embark on a moderate, roughly 40-minute hike along a well-marked trail that leads directly to the swimming spot. Be prepared for a somewhat rugged but family-friendly walk through the forest.

What to Expect

The spring’s atmosphere is peaceful, with the sound of cascading water filling the air. The pool at the brook’s base is cool and inviting year-round, offering a crisp contrast to New Hampshire’s warmer months. Crowds are generally sparse due to the moderate hike and limited parking, keeping the experience authentic and connected to nature. Facilities are minimal, so plan accordingly.

Tips for Visitors

Visit during weekdays or off-peak times to avoid the limited parking becoming an issue. Bring sturdy footwear for the hike and pack out all trash to preserve the natural setting. No fees apply, but respect the primitive environment by following Leave No Trace principles. A swimsuit and towel are essentials for this refreshing New Hampshire swimming hole.
