Agassiz Basin


Agassiz Basin is a lovely small waterfall located in Woodstock, New Hampshire. In total, the waterfall drops about 20 feet and it can be found right along Mount Moosilauke Brook. The brook’s source is Mount Moosilauke, so it often flows strongest during the springtime when the snow is melting. Due to this, it is best to visit Agassiz Basin during the spring to witness the most water flowing. The waterfall itself drops in a unique formation consisting of multiple plunges, cascades, and pools.

Although many photographers flock to the basin during the spring to capture the most water flow, it is a popular spot to visit year-round. Many locals love going to Agassiz Basin on hot summer days because the small pools at the waterfall are perfect for cooling off. Additionally, the basin is lovely during the fall when the foliage-covered trees surround the flowing water. 

Accessing the waterfall is super quick and parking is easy. The waterfall is located on private land, but visitors have long been welcomed. Just be very courteous and leave no trace, as always. Visitors of the waterfall can park in the dirt parking lot on the side of Lost River Road right near the intersection of Mountainside Road. After parking, the waterfall is located just a few steps through the woods. It takes less than 60 seconds to reach Agassiz Basin.
