RV travel guide
San Juan County
County seat Monticello, 7,820 sq mi across Utah. Everything an RV traveler should read before rolling in — where you can boondock, the roads worth the detour, and the local rule that actually matters.
The county in brief
A traveler's read on San Juan County
The Moki Dugway on UT-261 drops 1,200 ft in 3 miles on unpaved 10% switchbacks — UDOT bans any vehicle over 28 ft length or 10,000 GVWR, a constraint that locks out 90% of motorhomes and any travel trailer towed by a heavier-duty pickup. San Juan County is Utah's largest by area (7,820 sq mi) and holds the Needles and Maze districts of Canyonlands NP, all of Natural Bridges National Monument, the southern half of Bears Ears NM, and the northern half of the Navajo Nation's San Juan-River Goosenecks corridor.
Monticello (population 1,972) at 7,066 ft is the county seat; Blanding holds the only full grocery + diesel pump between Moab and Bluff. Canyonlands' Needles backcountry permits begin selling 4 months ahead and routinely sell out for spring + fall windows within 30 minutes of release.
