Know Before You Go
Before you dive into the cool waters of Glacier’s lakes, there are several things to keep in mind to ensure a safe and enjoyable experience.
Park Regulations and Closures
Swimming is permitted in most lakes within Glacier National Park, but always check for any closures or restrictions. The park’s pristine ecosystems can be fragile, and some areas may be off-limits due to wildlife protection, seasonal weather conditions, or water quality issues. If an area is closed there are typically signs at the trailhead, but it doesn’t hurt to check in with a park ranger at one of the visitor centers at the beginning of your trip.
Permits
You don’t need a specific permit to swim in Glacier’s lakes, but an entrance pass is required to access the park. An America the Beautiful Pass is the best option for accessing National Parks Annual. It has an $80 fee and can be purchased here.
Additionally, if you are entering the West Glacier Side of Going-to-the-Sun Road, Many Glacier, or North Fork between 6am and 3pm vehicle reservations are required which can be purchased at recreation.gov 120days prior to your visit or the day before at 7pm.
Some of the more remote lakes may require backcountry permits if you plan to camp overnight or hike long distances.
Responsible Recreation
Glacier National Park is a protected environment, so practicing Leave No Trace principles is essential. Avoid disturbing wildlife, don’t leave behind litter, and be mindful of fragile shoreline ecosystems. Avoid camping, stepping, and laying on vegetation. At high elevations, vegetation takes significantly longer to grow back.
Bear Aware
As with all outdoor activities in Glacier, it is crucial to be bear aware. Grizzly bears and black bears are often found near water sources, especially during the warmer months. Always store food securely, carry bear spray, and stay vigilant.

Lake Safety
The water in Glacier National Park’s lakes is typically cold, even in the summer. Hypothermia can be a risk, so limit your swim times and watch for signs of cold-water shock. Avoid swimming in and around fast-moving streams or rivers where currents can be dangerous.
Many people polar plunge in Iceberg Lake and Upper Grinnell Lake which have large amounts of ice in them through September.
Hyperthermia
If you or someone you’re with is experiencing uncontrolled shivering and a low body temperature, remove wet clothes and cover the body with blankets or insulated gear. Move to a warmer area and call for emergency services.
Pack Essentials
Apart from swimwear and hiking gear(if the lake requires it), be sure to pack sunscreen, towels, water shoes (the lake bottoms can be rocky), and warm layers to throw on after your swim. I would highly recommend packing a GPS device to aid in emergency situations, especially when swimming in the backcountry.
By keeping these tips in mind, you can make the most out of swimming in Glacier National Park!
Lake McDonald
Lake McDonald is the largest lake in Glacier National Park and is easily accessible from the West Glacier entrance. With crystal-clear water and stunning mountain views, it’s a popular spot for swimming, kayaking, and paddleboarding. Apgar Village, located at the foot of Lake McDonald, offers a good spot to dip into the lake where there is a small beach, but keep in mind that the water remains frigid even in the height of summer.
Staying at the Lake McDonald Lodge? You’re in a prime location for an evening swim on one of the best lakes in the park.
Swimming Tip: This lake has plenty of boat traffic. Be cautious when swimming too far away from shore.
Bowman Lake
Located in the remote northwestern section of the park through the North Fork Entrance. Bowman Lake offers a more secluded swimming experience due to its distance from the main entrances. The lake’s calm waters and peaceful setting make it ideal for swimming, though the water will be icy. The drive to Bowman is on a rough gravel road, which can deter some visitors, ensuring a quieter experience.
Stop in Polebridge on the way in for a Huckleberry Bear Claw to make the most out of your scenic drive.
Swimming Tip: Plan your swim for a warm day and enjoy Bowman’s quieter, more remote nature compared to Glacier’s more popular lakes.
Two Medicine Lake
Two Medicine Lake, in the southeast part of Glacier, offers stunning views of Rising Wolf Mountain and Sinopah Mountain. The water is frigid here, but adventurous swimmers often brave the chill for a quick dip after hiking the trails nearby. This area is also rather windy. You know what your dad says, “It’s not the temperature that gets ya… it’s the wind chill”.
The lake’s shores in the two medicine area are rocky, so water shoes can be helpful.
Swimming Tip: Two Medicine’s beach near the boat dock is an excellent spot for a refreshing post-hike swim, and you might also spot some local wildlife while you’re cooling off. If you don’t feel like jumping into the freezing waters…you can always rent a kayak here!
Hidden Lake
The only way to reach Hidden Lake is a 3-mile hike starting at Logan Pass. The lake sits beneath Bearhat Mountain, making for a dramatic backdrop as you swim. Fewer people swim here because of its remote location and colder temperatures, but those who do are rewarded with an unforgettable experience.
Logan Pass is situated on Going to the Sun Highway, which means you will need a Vehicle Registration Permit to access this lake during the year if you’re going from the west side of the park.
Swimming Tip: Be prepared for cold water and potentially limited swimming time. The hike is moderately challenging, so plan accordingly.
Avalanche Lake
Avalanche Lake is another excellent spot for swimmers who don’t mind a bit of a hike to get there. The trail to the lake is about 2.5 miles long and leads you to a beautiful alpine setting with waterfalls cascading down the surrounding cliffs. The lake itself isn’t too cold, due to its shallow lake bed. However, it is predominantly snow melt that feeds the lake, making for a chilly plunge at the beginning of the summer.
Tack Trail of the Cedars onto your hike since the two trails share a parking lot!
Swimming Tip: Avalanche Lake is one of the most popular day hikes and can get busy in peak season. Try swimming earlier in the day or later in the afternoon to avoid the crowds and find a parking spot at the Avalance Lake Trailhead.
Cracker Lake
Cracker Lake is one of Glacier National Park’s hidden gems. With its striking turquoise waters framed by dramatic peaks and cliffs, it is arguably the most beautiful lake in the park. The lake sits in the Many Glacier region and requires a 6.1-mile hike (one way) to reach, making it a more challenging swimming destination. What makes Cracker Lake stand out is its vivid color, caused by fine glacial silt suspended in the water, giving it a bright blue appearance that almost seems unreal. A similar thing happens to Peyto Lake in Banff National Park
This lake is situated at the end of a large mountainous canyon. Wind exposure can get rather extreme here. However, if you’re able to secure backpacking permits here I cannot recommend it enough.
Swimming Tip: Since Cracker Lake is located in Bear Country, make sure you’re carrying bear spray and be extra cautious. The last time I was here, there were two adolescent grizzly bears roaming around the area. Good luck!
Grinnell Glacier Lake
Grinnell Glacier Lake is a pristine lake at high elevation, making it absolutely gorgeous and frigid. As snow melts from Grinnell Glacier, it makes its way into Grinnell Lake. However, this amazing glacier park lake is one of the best places to take your polar plunge. You will receive some side-eye from fellow hikers, but pay them no mind!
Swimming Tip: Pack a nano-puff jacket or pullover fleece to use while you dry off. Even in the summer months, you will be chilly after jumping into this lake. Keep yourself moving to increase blood flow.
Lakes Outside of Glacier National Park
While Glacier National Park’s lakes are incredible, some nearby lakes outside the park are worth visiting for a
swim. Flathead Lake, the largest natural freshwater lake in the western U.S., offers warmer water and several public beaches, perfect for swimming. Other notable nearby lakes include Whitefish Lake and Hungry Horse Reservoir.
Swimming Tip: Flathead Lake’s water is warmer than Glacier’s alpine lakes, making it an excellent alternative if you’re looking for a more relaxed swim.
