Some of the best things to do in Bozeman in summer include hiking the trails. Residents and visitors take advantage of the numerous trails that start in town and wind into the Bridger, Gallatin, and Bangtail Mountain Ranges.
Once inside the park, stop at the Boiling River for a soak. There are two front country locations in Yellowstone where you can get into the hot water, and the Boiling River is the best one.
Missouri Headwaters State Park is where the Gallatin, Madison, and Jefferson Rivers come together to form the Missouri River. When the Lewis and Clark Expedition arrived here in 1905, they had to decide which one would lead them to the mountains and eventually the Pacific Ocean.
Helena, like most of Montana, has a lot of outdoor activities to offer. In summer, hike and bike in the local hills and mountains. Winter brings cross-country skiing, ice skating, and snowmobiling.
One of the highlights of a visit to Montana is a dip in a hot spring. At Norris Hot Springs you can soak outside, eat local food, and listen to a band from the pool.
