The refreshing cold water and serene atmosphere of Bowman and Kintla Lakes make them the perfect spots for a peaceful and refreshing swim, away from the crowds of the more popular destinations in the park.
Swimming in Avalanche Lake

For those willing to take a hike, Avalanche Lake is a gem within Glacier National Park. The Avalanche Lake Trail is a popular hiking trail that takes you through old-growth cedar forests and along a rushing creek before arriving at the stunning lake. It’s 2.3 miles (one-way) with an elevation gain of 500 feet.

Swimming in Hidden Lake

Accessible from the Logan Pass Visitor Center on the famous Going-to-the-Sun Road, Hidden Lake is a high-elevation alpine lake that offers breathtaking panoramic views of the surrounding mountains. Although the water is cold year-round, taking a dip in the clear waters of Hidden Lake is a rewarding experience after a hike along the Hidden Lake Trail.
Keep in mind that the trail may be closed due to grizzly bear activity, so it’s important to check for trail closures before embarking on your adventure. And remember, it’s quite a climb up out of the lake basin after your swim.
Swimming in Two Medicine Lake

Located in the southeastern part of the park, Two Medicine Lake is a peaceful and serene destination for swimming. The lake is surrounded by towering peaks, and its calm waters make it an ideal spot for a leisurely swim.

Swimming in St. Mary Lake

St. Mary Lake is another popular destination for swimming in Glacier National Park. This picturesque lake is located along the Going-to-the-Sun Road and offers stunning views of the surrounding mountains, including the famous peaks of the Continental Divide.

Swimming in Upper McDonald Creek

For those seeking a more secluded swimming hole, Upper McDonald Creek offers a peaceful and serene spot to cool off during the hot summer months.
Access the Upper McDonald Creek Trail from the Going-to-the-Sun Road on North Lake McDonald Road. There is a small parking area on the right about 3/10 of a mile after turning off the GTTS Road. Or use the pull-off near the bridge over McDonald Creek, or the large lot at the junction of North Lake McDonald Road and the GTTS Road.
Walk along the Upper McDonald Creek Trail alongside the creek until you find a good place to wade in. Be careful, of course, in this sometimes fast-moving creek and choose one of the quiet pools or rocky beaches to relax in.
As you venture out to swim in Glacier National Park, it’s important to be mindful of the park’s rules and regulations. Always be aware of the potential presence of grizzly bears and other wildlife, especially when swimming in remote areas.

It’s recommended to bring appropriate swim gear, including wetsuits or drysuits, to ensure a safe and enjoyable swimming experience.
