• Spring: Possible rain; waterfalls active; cool mornings
• Summer: Scorching desert; drive early morning or evening
• Fall: Golden sunsets; crisp air; ideal for hiking stops
• Winter: Snow possible north of St. George; check passes like I-15 near Ogden

Infrastructure Safety and Road Quality

Interstate 15 is well-maintained but can be congested near Salt Lake City and Las Vegas. Rural stretches in Utah and Nevada have limited cell coverage (especially between Beaver and St. George). Always carry water, snacks, and a paper map. Roadside services: AAA and towing available via 911 on most highways.

• Road condition: Good; watch for truck traffic near Las Vegas
• Rest stops: Utah rest areas (e.g., near Holden) are clean; California ones require planning
• Safety tips: Desert heat can cause blowouts; check tire pressure

Natural Landscapes and Attractions

From the snow-capped Wasatch Range to the red rock canyons of southwestern Utah, the route is a visual feast. Zion National Park (Springdale, UT, 37.2982° N, 113.0263° W) is a must-detour—just off I-15. The Mojave Desert offers stark beauty with Joshua trees and volcanic cinders near Cinder Cones Natural Area.
