Are you looking for a lake in the Adirondacks to kayak or canoe? Do you want one with free campsites? Are you looking for one with access to other bodies of water? Blue Mountain Lake will fit the bill.
The boat launch is located on State Route 28. It is a public beach and boat launch. Route 28 has parking spots on both sides of the street. This May weekend I was the only one launching from the beach. I did not see another kayak or canoe on the lake. This site has a pavilion with changing rooms that were locked. Maybe they open when it is warmer or they are still following a COVID protocol.
Blue Mountain Lake is accessible to other bodies of water. It connects to Eagle Lake and from there you can paddle to Utowana Lake. For those who want a very long journey you can access Raquette Lake from the Marion River at the end of Utowana Lake.
This lake has some free campsites. It is first come first served. There are 4 primitive sites on Long Island and 1 on Osprey Island. Bring your gear on your kayak or canoe. As with most Adirondack free sites there is a three day limit unless you get permission from a ranger to stay longer.
This lake gives you some nice views of the neighbouring mountains. It is close to other lakes, so you could even hit Long Lake , Indian Lake etc. by car in the same day after kayaking. I highly recommend this lake if kayaking or canoeing. You may want to stick the the edges to avoid the wind.
The Adirondack Experience is very close-by and worth stopping at. They also have marvellous views of Blue Mountain Lake from their cafe patio. The Adirondack Experience is a museum with several buildings including cabins, cottages, and camps of the past brought to the museum. You get a feel for what life and pleasure was like in the Adirondacks in yesteryear.
