Lewis Lake Campground is a National Park Service campground near Yellowstone's South Entrance, set on the shore of Lewis Lake in the park's southwest corner. It is the most rustic developed campground in Yellowstone and, in our guide's words, the tightest for RVs. Paddlers love it, and it works well for vans, truck campers, and small trailers arriving from Grand Teton who want quiet rather than services. Our Yellowstone guide covers it briefly; the practical details below come from that guide.

|---|---|
| Sites | Around 80. |
| Max RV length | About 25 feet — best for vans, truck campers, and small trailers. |
| Cost | Around $20–$25/night. |
| Reservations | Recreation.gov. |

This is dry camping in the plainest sense: no hookups, vault toilets, and no showers. The listed length limit is about 25 feet, so most trailers and Class As are out. Around 80 sites cost roughly $20 to $25 a night and are booked on Recreation.gov. The season is short, roughly mid-June into early November as conditions allow, and Yellowstone nights are cold even in July. The trade-off is remoteness. You are far from Old Faithful and the lake developments, so this is a base for a quiet lakeside stay, not for touring the whole park.
