Custer-Gallatin National Forest
Guide

Introduction

With more than three million acres spanning over 400 miles, the Custer-Gallatin National Forest includes many different ecosystems. You can find a huge stretch of Yellowstone acreage, the high country of the Absaroka-Beartooth Wilderness, and the vast and rugged Gallatin Crest, to name a few. Each with their own diverse landscape and beauty, these combined forests make up one of the largest intact ecologically diverse landscapes in the country. While Custer and Gallatin are two distinct areas, they are managed together as Custer-Gallatin National Forest.

Established in 1899, the Gallatin National Forest has four ranger districts, which include Yellowstone, Hebgen Lake, Gardiner, and Bozeman. Besides many fun activities here such as boating, fishing, swimming, hiking, and RV camping, you will also find several federally threatened species here. These include the Canada lynx, bald eagle, gray wolf, and the grizzly bear. You can have fun in the winter here with hundreds of miles of cross-country skiing trails, as well as ice fishing and snowmobiling. There are six separate mountain ranges in the forest, which include the Beartooth, Bridger, Madison, and Gallatin.

The Custer Forest includes the 12,799-foot Granite Peak, which is the tallest mountain in Montana and Grasshopper Glacier, which is a national wonder that holds millions of grasshoppers frozen in the ice. There are three ranger districts in Custer including Ashland, Sioux, and Beartooth. If you are looking for a scenic drive, the Beartooth Highway in Custer will take you from Red Lodge to Yellowstone Park in the Gallatin National Forest. For RV camping at its most rugged, you can choose from 12 different campgrounds. We chose our top three favorites and highlighted them below.

Transportation

Driving

Just a short drive from Billings and five hours from Missoula, the Custer-Gallatin National Forest is an easy and gorgeous drive away from just about anywhere in the northwestern section of the United States. Coming from the north, east, or west, you can take Interstate 90 or 15 and Highway 212 from the south. The forest spills over into northwestern Wyoming, but the majority is in Montana.

The scenic Beartooth Highway is one of the most stunningly diverse and beautiful drives in the United States and connects the Yellowstone Park to the quaint mountain town of Red Lodge, Montana. With 68 miles of winding road, you can see buffalo, elk, and deer as well as eagles, foxes, and raccoons throughout the forest. During the winter, the road is closed to cars but is open to snowmobiles, which gives you another fantastic way to explore the forest.

As you get deeper into the woods, you will start noticing that the streets are narrower and curvier and can be dangerous for those driving a large campervan or pulling a trailer. There is not much room for error on these roads, so it is important to drive carefully no matter what you are driving. Once you get to the campground, it is best to park your rig and walk or ride a bike to wherever you want to go, if possible.

Seasonal activities in Custer-Gallatin National Forest

In-Season

Picnicking

Pack up your family and friends in the RV and head to the Custer-Gallatin National Forest for a picnic. There are so many picnic areas in the forest that you could go to a different one every day for a month and not visit them all. Each pavilion has picnic tables, BBQ grills, and many of them have electricity and water. Some of them are on the water and there is usually a restroom and playground nearby. If you don’t need a large pavilion, there are hundreds of individual picnic areas all throughout the forest with picnic tables and BBQ pits.

Fishing

The Custer-Gallatin National Forest has thousands of miles of rivers and streams with tons of hungry fish so pack your fishing poles in the camper before coming. There are also hundreds of reservoirs and lakes where you can find three different species of trout, as well as Utah chubs, crappie, and bass. Whether you are fishing the lakes or rivers, both topwater and bottom fishing are recommended with artificial lures, jigs, and live bait. And don’t forget your fishing license.

Grab your climbing gear and put it in the RV. With all of the mountain ranges in the Custer-Gallatin National Forest, how can you resist doing some climbing?
