Glacier National Park (or Waterton Lakes National Park on the Canadian side), is a truly breathtaking area. There are many hikes in the park, including the adventurous Highline trail, which can be accessed from the famous Going to the Sun Road.

However, this is an extremely popular area. Don't expect to drive up and find vacancy or available campsites without reservations far in advance. Even day access needs to be reserved well in advance, or at 7pm sharp the day prior.

Just a 20 minute drive from the venue is the spectacular Holland Lake. A three mile total out and back hike along the lake leads to a gorgeous waterfall. Longer hike options are available from the same trailhead.

There are a multitude of nearby lakes that offer excellent stand up paddleboarding, kayaking, swimming, etc.

This includes Holland Lake, Van Lake, Seely Lake, Lindbergh Lake, & Swan Lake.

On a grander scale, Flathead Lake and Hungry Horse Reservoir are spectacular large bodies of water nearby.

1 - 2 hours north of Condon, the Bigfork to Whitefish area offers a wide variety of excellent mountain biking, including bike rentals.

Hike the scenic backdrop of the wedding venue - 5 miles and 4,500 vertical feet of elevation gain one way, this is a full day hike with lots of water and snacks required.

If you plan to extend your visit (please do), reach out to the couple for their recommendations for more activities in their hometown of Bozeman.

Bozeman is in closer proximity to Yellowstone, as well as other destinations such as Hyalite Reservoir.
