If you’re looking for cool, crisp water for swimming this summer, then you’ll love Blue Mountain Lake. This high-elevation lake is right in the middle of the triangle made by Indian Lake, Raquette Lake, and Long Lake. While the other three lakes are often busier, don’t overlook this very special and very beautiful lake. The water at Blue Mountain Lake will be cold even in the summertime, but that shouldn’t stop you. Take a dip for ultimate refreshment!

Blue Mountain Lake is gorgeous. It's at an elevation of 1,824' in the middle of Adirondack Park.

This lake is quite large, and rather deep in places as well. It covers 1,334 acres and is 2.5 miles long and 1.25 miles wide at its longest and widest points. Its average depth is 46 feet, but it's as deep as 100 feet in some places.

Because of these facts, it should be no surprise to anyone that it's quite cold. Even in the summertime, the highest average local air temperature is just 74 degrees Fahrenheit in July.

Still, people do enjoy swimming in Blue Mountain Lake. This lake has 10 islands. It's fun to boat out to them and jump off of them into the lake.
