With a whopping 3,223 named lakes and reservoirs in Montana, it’s safe to say that we’ve got plenty of places to enjoy fishing, swimming, boating and just lounging by the beautiful shore. From Seeley Lake to Flathead Lake to Eastern Montana’s Fort Peck Reservoir, every part of our great state has an abundance of freshwater fun available.

Catching a first glimpse of it from over a hillside after a good hike takes your breath away… it’s so beautifully blue that it looks turquoise. In a state full of stunning lakes and rivers, this body of water really stands out.

This is one of the most beautiful hikes in the entire park, if not the entire Northwest. The trail, which is well-maintained, takes you beneath the massive melting glacier with sweeping views of hillsides, waterfalls and wildlife. It’s not uncommon to see floating icebergs in the lake from the melting glacier.
