Caribou-Targhee National Forest
RV Guide


The Caribou-Targhee National Forest makes up 2.63 million acres of the 20-million-acre Greater Yellowstone Ecosystem. The majority of the forest is situated in the states of Idaho and Wyoming, although there is a small pocket in Utah as well. Hundreds of miles of trails crisscross this region, allowing visitors to experience the beauty of this amazing ecosystem, and the abundance of wildlife that lives here, including sensitive or threatened species like Townsend’s big-eared bat, lynx, and trumpeter swans. The many lakes, rivers, and streams that are located in Caribou-Targhee National Forest are filled with rainbow trout, cutthroat trout, and several other species. There are also several mountain ranges that pass through the forest, including the Teton and the Lemhi mountain ranges, which provide many opportunities for rock climbers to challenge themselves.

There are over a dozen campgrounds that are situated throughout Caribou-Targhee National Forest, each of which has facilities to host RVs and trailers. Whether you are towing a small trailer or driving a big rig, you shouldn’t have any trouble locating a spectacular spot to park for a night or two. We have highlighted three of the wonderful campgrounds that can be found in this forest.

RV Rentals in Caribou-Targhee National Forest



There are several campgrounds that are scattered throughout this 2.63 million-acre forest, both on the Idaho side and on the Wyoming side. The highways and roads that lead into the park are wide roads with just a few curves, and they tend to be easy to navigate even in a big rig or towing a trailer. The Caribou-Targhee National Forest is a mountain wilderness, however, and you should expect some changes in elevation as you drive. The majority of the roads that go through the forest itself are also paved, but they are narrower. Since they are mountain roads, they tend to have a greater number of twists and turns as well as altitude changes.

There is a large population of wildlife in this park, so it is important to watch the road as you drive. It is not uncommon to see deer, bighorn sheep, or even bears attempting to cross the road, typically without any warning. This is especially true during the dawn and dusk, as these animals tend to be more active during these times.

Most of the campgrounds in this forest have well-maintained dirt and gravel roads and driveways, although a few of the larger ones have paved loops and concrete pads for your camper or trailer as well.
