This One Lake Has The Absolute Bluest Water In Montana

Grinnell Lake in Glacier National Park, Montana, is renowned for its stunning turquoise color caused by rock flour from the Grinnell Glacier.

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. But let's take a closer look at one particularly blue lake in Montana that's got everyone's attention.

There’s something truly surreal about Glacier National Park’s Grinnell Lake.

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. There’s an interesting natural phenomenon behind Grinnell Lake’s opaque turquoise appearance: when rock flour (silt) moves from the Grinnell Glacier into the lake, it mixes with the water and creates its unique hue. The results are astounding.

Typically hikers will have until late October to take the Grinnell Lake Trail to the lake.

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.

The trail to the lake is 7.2 miles long out and back, but it’s a pretty easy path, and it’s totally worth it.

You can also take a boat tour across Swiftcurrent Lake and Lake Josephine to shorten the distance.

Just look at this stunning lake. How lucky are we?

We don't know about you, but we could spend a lifetime here.

It really is Montana at its most astonishing.
