Great nontechnical hike to the summit of one of Bozeman's iconic southern peaks. A few stream crossings for filtration if you want to go light. Some steeper grades just up from the lake, but mostly very manageable grades, gorgeous views! Mountain goats were seen as well. Highly recommended.

Ousel Falls Trail in Big Sky offers a short, scenic hike along the South and West Forks of the Gallatin River, crossing three bridges before reaching the stunning waterfall. At the trail split, hikers can choose from four paths: the South Fork Overlook, the top of the falls via a natural footpath, the base of the falls with a picnic area, or the rocky Ousel Falls Overlook. This popular trail is best hiked between May and October, and dogs are welcome. Do note that roads to the trailhead may be seasonally closed.

The final stretch to the summit can be a slog and may end up being more of a hike than a bike, however, the views more than make up for the effort. Also, the fire lookout at the summit is available for overnights so check recreation.gov if you plan to do some bikepacking.

Hyalite Reservoir is a large artificial lake that affords opportunities for day-use hiking, easy strolls, or the perfect launching point for more aggressive, big-mountain singletrack riding. Even if a bit busy, plenty of parking is available.
