  • Beaverponds Trail #105: At 2.67 miles this ride will get your blood pumping but not annihilate you. The trail which connects with the Continental Divide Trail will lead you past many beaver dams.

Catch a prize rainbow trout on the famed Madison River. Maybe a pale morning dun hatch will greet you as you try your luck in Wade or Cliff Lakes. As home to numerous headwaters and alpine lakes the amount of fishing you do depends on how fast you can cast. Don't forget a fishing license, found at any local fly shop! When you are there, chat it up with the locals, they may let you in on the local hot spots.

Fun Facts

The Beaverhead-Deerlodge National Forest may not have become what it is today without the help of local settlers and politicians alike. Back in 1908, President Theodore Roosevelt heard a lot of complaints from both the settlers and conservationist, leading him to set aside this land for future protection.

The extensive clear cutting being carried out by the Anaconda Mining Company was causing excess soil erosion thus contaminating and destroying the Big Hole River watershed. This compounded with throat clogging smoke pollution led them to action. This early stewardship laid the foundation for the current Beaverhead-Deerlodge National Forest, today an adventurer's vast playground.
