Flaming Gorge National Recreation Area is ringed by more than 40 developed campgrounds, most managed by the Ashley National Forest and clustered around the reservoir's three main areas: the Manila/Sheep Creek side on the west, the Dutch John/dam side in the middle, and the Green River, Wyoming side to the north. Most campgrounds run mid-May through mid-September, and nightly fees average around $15, though sites with hookups or group capacity run higher.
With that many options, the question isn't really "which campground is best" — it's "which area fits your trip." Here's a breakdown by what you're actually planning to do.
If You're Boating or Fishing the Reservoir
Campgrounds closest to a marina save you the most drive time with a boat in tow. On the Utah side near Manila, Sheep Creek Bay Campground, Carmel Campground, and Willows Campground sit close to Lucerne Valley Marina. Near the dam, Cedar Springs Campground and Firefighters Memorial Campground put you minutes from Cedar Springs Marina and the boat ramp at the dam itself.
If You're Fly Fishing the Green River Below the Dam
Dutch John is the base for this. Mustang Ridge Campground and Dutch John Draw Group Campground sit closest to the Green River corridor and the Little Hole National Recreation Trail, putting you within a short drive of the blue-ribbon water without needing to be on the reservoir at all.
If You Want Fewer People and Lower Elevation Heat
Dripping Springs Campground and Arch Dam Group Campground tend to see lighter traffic than the marina-adjacent sites, while still offering reservoir or river access.
If You're Coming from the Wyoming Side
Green River, Wyoming isn't directly on the reservoir but functions as the practical base for the northern end and the Flaming Gorge-Uintas Scenic Byway loop. Rock Springs/Green River KOA Journey offers full RV hookups and is the most amenity-heavy option in the area — useful if you want a real shower and laundry between days on the water.
Reservable vs. First-Come-First-Served
Most of the larger campgrounds take reservations through Recreation.gov, and popular sites — especially anything near a marina — book up well ahead for summer weekends. A handful of smaller, more remote campgrounds remain first-come-first-served, which is your best bet for a same-day or last-minute site during peak season, at the cost of no guarantee you'll find a spot.
The Bottom Line
Don't pick a campground first and figure out your plans second — pick your activity (boating, fly fishing, or just passing through on the byway) and let that narrow you down to one of the three areas. From there, book early for summer weekends, especially anything within walking distance of a marina.
