What Guests Are Saying
Mammoth Campground offers clean facilities, friendly staff, and a beautiful location near Mammoth Hot Springs, making it an excellent base for exploring Yellowstone. Many reviews highlight the well-maintained bathrooms and accessible water spigots, as well as the stunning views and quiet atmosphere. However, some campers noted a lack of shade, noise from nearby traffic, and limited trail access, but overall, the campground is highly recommended for its amenities and scenic surroundings.

Josh and Lucy solved a vacation ending issue with our reservation, and we found Mammoth Campground to be clean, inviting and comfortable in our 21' campervan. This is the opposite of what we found at the Tower Falls CG...

This campground is conveniently located near the entrance roads, the hot springs and the small town itself, yet is tucked away in its own private place.

Beautiful view and roomy spots. Bathrooms are close to camping spots. 2 minute drive from shops and restaurants, sulfur pools are also close by which make a cool stop. Had no issue with check in or park rangers. My one issue was the lack of cell service, I use AT&T and lacked service throughout most of the park. My friends with Verizon were able to get service to it just depends on your carrier. Would absolutely recommend this spot if you're able to reserve it.
