Grotto Falls

The Hyalite Creek Trail offers a moderate hiking experience through a stunning glacial U-shaped canyon. As you hike, you will pass through dense coniferous forests and open meadows, with the sound of rushing water accompanying you. The route is famous for its many waterfalls; you can expect to see at least eleven cascades, including the notable Hyalite Creek Waterfalls and Grotto Falls, as you ascend. This trail covers 6.0 miles (9.7 km) with an elevation gain of 1109 feet (338 metres), typically taking around 2 hours and 53 minutes to complete.

When planning your visit, be aware that the trail includes varied terrain with rocky sections and roots. You will also encounter several stream crossings that do not have bridges, so waterproof footwear is a good idea. Snow can linger at higher elevations well into spring and summer, which can make conditions slick during colder months. Always check local regulations, as the trail is multi-use and may have specific days for different activities.

This route provides increasingly grand canyon views as you climb, with massive cliff walls and majestic peaks framing your path. It is a popular choice for those seeking a rewarding outdoor experience close to Bozeman. The trail's unique geological features, like the U-shaped canyon, highlight the powerful forces of nature that shaped this landscape, making it a distinctive hike in the Custer Gallatin National Forest.
