Moss Island in Little Falls, NY is a small island wedged between the Mohawk River and the Erie Canal, declared a National Natural Landmark in 1976. It is one of the most distinctive geological and outdoor recreation destinations in Central New York, and Grand Colonial Bed and Breakfast in Herkimer sits about 15 minutes west on Route 5, making it the natural base for a Moss Island weekend.
Why visit Moss Island
Moss Island is famous for two things. First, the glacier-carved potholes. The largest are 40 to 50 feet deep, formed by an ancient waterfall that once drained Glacial Lake Iroquois when other outlets like the St. Lawrence were blocked by ice. At its peak the waterfall here was larger than Niagara. Today the dry potholes remain as immense cylindrical pits in the syenite bedrock, a geology lesson you can stand inside.
Second, the climbing. Moss Island is one of the best trad-climbing crags in Central New York, with over 100 established routes ranging from 5.1 beginner slabs to 5.13 expert problems. Goat Crack (5.2) is a 45-foot beginner-friendly classic where many local climbers do their first lead. The approach is famously short, most routes are a few minutes from the parking area, making it a popular weekend destination for climbers from across the Northeast. Lynn Hill is among the famous names who have climbed here.
Planning your visit
The island sits across the canal from Canal Place in downtown Little Falls. Trails wrap around the geological formations and lead to overlook viewpoints over the Mohawk River and the village. Erie Canal Lock 17, the highest-lift lock in the state, is right next door and is part of the same walking experience.
Bring sturdy footwear. The terrain is rocky and uneven, and even if you are not climbing, the descent into the potholes requires careful stepping. Climbers should bring full trad gear; there is no nearby outfitter for renting equipment on short notice.
Parking is along the canal-side road with a short walk in. There are no formal restrooms on the island. Pack water, especially in summer when the rock heats up quickly.
