No tents allowed! Not even tent campers. It's a super busy area because it's right next to Hayden Valley, where you find a ton of wildlife that Yellowstone is famous for.

Can't build a fire, even if you have the portable fire pits. The area is prone to wildfires. However, the park rangers are very friendly, great with kids, and host evening talks in the amphitheater. We learned about the bats that fly around the area at night.
