Lewis Lake Campground campground
Lewis Lake Campground
Nearby points of interest include the Lewis River Channel, which is a great spot for fishing and hiking. The Lewis River Channel Trail, which begins near the campground, offers a picturesque walk along the river and through the forest. The South Entrance to Yellowstone National Park is only a short drive away, providing easy access to all of the attractions in the park.
The campground amenities include a well-maintained restroom facility, potable water, and trash collection services. There are also picnic tables and fire rings at each campsite, and firewood is available for purchase on-site. The campground is open from early May to mid-October, but the specific dates may vary from year to year.
One interesting fact about the area is that Lewis Lake was formed as a result of a massive landslide that blocked the Lewis River. The landslide occurred in 1959 and created a natural dam that created the lake.
