RV Guide


Located just outside of Helena, Montana, Lewis and Clark National Forest is a pristine natural reserve set in the rugged Rocky Mountains. Hundreds of miles of multi-use trails take you through the forest, and you can also connect to the Continental Divide Trail.

Anglers will find plenty of opportunities in the forest as well. Gibson Reservoir has excellent brook and cutthroat trout fishing, and you can find brook trout at Bell Creek.

Seasonal activities in Lewis and Clark National Forest


Ice Fishing

If you visit during the winter, pack your ice fishing gear in your camping trailer. When the lakes freeze over, the fish stay active, so you’ll still get plenty of bites. Crystal Lake is one of the most popular ice fishing destinations in the area, and you’ll find dozens of other spots in the forest. Forest officials do not monitor ice conditions on all of the lakes, so fish at your own risk. The lakes are usually safe by January, but you should always get up to date information on ice status before fishing.


The hundreds of miles of hiking trails in the forest can still be used during the winter, so make sure to pack your snowshoes along with your rig. Popular routes include the Continental Divide Trail, a 67-mile long stretch that connects to many of the main RV campgrounds in the area. You can also hike up to Granite Butte Lookout for some of the best views of the forest. Take caution while snowshoeing, as there is an avalanche risk during the winter. You should also be on the lookout for grizzly bears when you head out of the camper in your snowshoes.

Cross-Country Skiing

Visitors during the winter will find hundreds of miles of cross-country skiing trails that cut through the forest. You’ll be able to enjoy scenic views of the Big Belt Mountains as well as the open fields of the lowlands. Trail conditions vary depending on where you are in the forest. Some of the trails are maintained throughout the winter, while some are left entirely ungroomed. The trails are generally geared towards intermediate to advanced skiers, although there are still plenty of routes for beginners.



The diverse ecosystems found throughout the forest are home to a wide range of big and small game species. Deer and elk are the most popular game in the area, and you can also hunt for a range of small game and waterfowl. Take caution while hunting, as there are a number of hiking trails that cut through popular hunting areas. Also make sure you have all of the required Montana state hunting licenses. The forest is in the middle of grizzly bear country, to take proper safety precautions.


Anglers will find a range of opportunities throughout the forest. There are dozens of lakes and streams, many of them close to the main RV campgrounds.

The fishing is excellent throughout the year, with most anglers having the best luck starting in late spring running through early fall. Most of the campgrounds don’t rent fishing gear, so bring all of the equipment you need along with your campervan.
