Local Area

Crazy Mountains

There are several legends as to how they got their name. One of them is that a woman (some say Indian - some say white) went mad on the prairie, possibly due to the death of her family, and took refuge in the mountains. Indian beliefs require that crazy people to be left alone, and so she was.


Natural Bridge State Park

A 30 minute drive south of Big Timber brings you to Natural Bridge Falls. The paved paths start at the parking lot and meander along the Boulder River. There are several viewing points with signs telling about the area, falls and wildlife. In the spring there are actually three separate falls. Later in the year the river flows underground to reveal the limestone bedrock. Toilet facilities and picnic tables are available. A well maintained dirt trials leads to a scenic point directly across from the falls. For a day hike continue on the Green Mountain Trail. The terrain will change from grassland to heavy timber. Look for Limber pine, Lodge Pole Pine, Douglas Fir and wildflowers galore. Deer, bear, elk, and small animals may be seen along the way.


Big Timber Falls at Halfmoon Park

Take 191 north out of town less than 10 miles, then take a left on Wormser Loop Rd.  Enjoy the beautiful drive as you follow Big Timber Creek into the Crazy Mountains. Halfmoon Park is equipped with picnic areas, a parking area for day hikes, and public restrooms.  It's a short and easy hike from the parking area to the majestic Big Timber Falls. For the hardier and more adventurous, Blue Lake is another 5.5 miles up the trail and offers beautiful surroundings and great fishing!


The Yellowstone and the Boulder River

These are two of Montana's finest trout fishing rivers. Get away for a day of fishing on your own, or we will help you locate a guide.
