Las Vegas to Ouray Road Trip Guide

The route from Las Vegas, NV to Ouray, CO spans roughly 600 miles along US-95, I-15, and US-91, crossing three states and climbing from the Mojave Desert to the San Juan Mountains. This drive passes through the ghost town of Calico, Utah's red rock country, and the Million Dollar Highway.

One notable fact: the section from Monticello to Moab crosses the Colorado River at an elevation of 4,000 feet, then ascends to over 10,000 feet at Red Mountain Pass near Ouray. The total drive without stops takes about 10 hours, but most travelers spend 2-3 days exploring.

Key natural landmarks include Valley of Fire State Park, Arches National Park, and the San Juan Skyway. For logistics: gas stations are sparse between Baker and Delta, and cell service drops in canyons. This guide covers how to find the best stops and hidden gems between cities.

From the red sandstone of Valley of Fire to the white salt flats near Milford, the variety is staggering. Valley of Fire, Nevada's oldest state park, features petrified trees and 3,000-year-old petroglyphs. Entrance is $10 per vehicle.

• Natural Attractions: The Wave (Permit required), Cedar Breaks National Monument, Arches National Park (entry $30).
• UNESCO Sites: None directly on route, but Mesa Verde National Park (former Ancestral Puebloan cliff dwellings) is a 2-hour detour from Cortez.
• Local Commerce: St. George's historic downtown has boutique wineries. Moab's Main Street is lined with gear shops and art galleries selling turquoise jewelry. In Ouray, the Ouray County Museum offers mining artifacts. The Ouray Hot Springs pool is open year-round.

Culinary highlights: in Las Vegas, pick up Red Rock beer and bison jerky. In St. George, try Dutch Bros coffee. Moab has the Moab Brewery and Desert Bistro. In Ouray, the Brickhouse serves Southwestern fare and the ice cream parlor on Main Street is a hit.

Fuel stops are critical: fill up in Las Vegas, St. George, and Moab. The longest gap without gas is between Hanksville and Green River (about 70 miles). Premium fuel is available in Moab and Monticello but may be limited. Expect gas prices to rise by $0.50/gallon in remote areas.

• Rest stops: Overton Wildlife Management Area (NV), Long Canyon Rest Area (UT), and the Colorado Welcome Center at Fruita.
• Road quality: US-95 from Las Vegas is well-maintained. I-15 to St. George is smooth. US-191 from Moab to Ouray has steep grades and tight curves, especially through Red Mountain Pass.
• Cell coverage: reliable in cities, but dead zones from Baker to Delta, and along the San Juan Skyway.

For cyclists and electric vehicles: charging stations are present in St. George and Moab, but sparse elsewhere. If towing, avoid US-191 via the Utah-Colorado border due to 10% grades. Instead, use I-70 to Grand Junction and US-50 to Montrose.

Winter conditions: Red Mountain Pass (11,018 ft) can have snow from October to May. Chains may be required. Drive during daylight hours. The Million Dollar Highway (US-550) lacks guardrails in sections. Summer brings thunderstorms and flash floods in slot canyons.

• Family suitability: Many stops have kid-friendly hikes. At Valley of Fire, the White Domes loop is 1 mile. Arches has the Windows section (1-mile paved loop). Ouray's Box Canyon Falls is near the highway and has a short bridge walk.
• Pet-friendly: Dogs allowed on leashes in most national parks on paved trails. Zion and Arches have kennels in nearby towns. In Ouray, the Ouray Ice Park area allows dogs but not in the Hot Springs pool.
• Fatigue management: Plan breaks every 2 hours. Rest zones: the NV Rest Area at Crystal Springs (mile 56 on US-95), the Beaver City Rest Area off I-15, and the Colorado Welcome Center near Fruita.

Hidden off-route spots: Goblin Valley State Park (off UT-24) has bizarre hoodoo rock formations, less crowded than Bryce Canyon. The Tule Valley Petroglyph Site near Fillmore is a free, low-traffic spot. Natural Bridges National Monument near Blanding has three natural bridges but requires a dirt road detour.
