Page AZ to Sun Valley ID: Ultimate Road Trip Guide

This route from Page, AZ (home of Antelope Canyon and Lake Powell) to Sun Valley, ID (America's first destination ski resort) spans roughly 800 miles across the Colorado Plateau, Basin and Range, and Rocky Mountains. The driving time is about 12–14 hours without stops, but the journey deserves at least 3 days.

Along the way, you'll traverse US-89, I-15, and US-93, crossing the Glen Canyon Dam, the Virgin River Gorge, and the Snake River Plain. The elevation climbs from 4,300 feet in Page to over 6,000 feet in Sun Valley, with dramatic shifts in climate and terrain.

A little-known fact: the segment through the Virgin River Gorge (I-15 between St. George and Mesquite, NV) was completed in 1973 and is one of the most expensive interstate sections per mile due to the rugged canyon terrain. This drive is a geologic masterpiece showcasing 1.8-billion-year-old Vishnu Schist (Grand Canyon basement rock) right from the highway.

Road Quality and Conditions

US-89 from Page to Kanab is a two-lane scenic highway in good condition but can be congested near national parks. I-15 through Utah is well-maintained, with wide shoulders and rest areas every 30-50 miles. The Virgin River Gorge section has steep grades and sharp curves; drive with caution in wet or icy weather.

US-93 from Salt Lake City to Sun Valley is mostly rural interstate or divided highway, with long stretches through high desert. Winter conditions (Nov–Mar) can bring snow and ice, especially over Monida Pass (elevation 6,820 ft) near the Idaho border.

UNESCO World Heritage Sites

The route passes near two UNESCO sites: the Grand Canyon (via a detour from Page) and the Lower Valley of the Gila River (not directly). However, the primary UNESCO-adjacent attraction is the Zion National Park (part of the Grand Staircase-Escalante region, a tentative site). A 1-hour detour from St. George leads to Zion's east entrance, famous for the Zion-Mount Carmel Tunnel and Checkerboard Mesa.

Infrastructure Safety & Road Quality

The Virgin River Gorge has no shoulders in places; use pullouts for photos. In winter, carry chains (required in some canyon areas). Rest areas are frequent along I-15 but sparse on US-93 north of Twin Falls.

Pet-Friendly Framework

Pets are allowed at many outdoor attractions but not inside buildings (e.g., Antelope Canyon requires leashes, but only on tours that permit). In national parks like Zion, pets are restricted to paved paths and not on trails. For overnight stops, hotels like La Quinta in St. George and Motel 6 in Salt Lake City are pet-friendly with low fees. Rest areas have pet exercise areas.

Hidden Off-Route Spots

For adventurous travelers, consider these detours:

• Paria Ghost Town (east of Kanab) – abandoned film set town on BLM land.
• Grafton Ghost Town (near Zion) – one of the best-preserved ghost towns in Utah.
• Jemez Mountains (east of I-25, not directly) if you take a longer route through NM.
• City of Rocks National Reserve (south of Twin Falls) – granite spires popular with rock climbers.

Fatigue Management & Rest Zones

Plan to stop every 2 hours or less. Ideal rest stops:

1. Kanab, UT (mile 75) – plenty of cafes and parks.
2. Beaver, UT (mile 300) – large rest area with picnic tables.
3. Salt Lake City (mile 425) – stay overnight to explore.
4. Pocatello, ID (mile 550) – a good lunch break with local diners.

For longer rests, consider overnight stays in St. George or Salt Lake City to recharge. If driving straight through, a hotel near Twin Falls (mile 680) is wise.
