St. George to Garden City: Utah's Ultimate Road Trip Guide

The drive from St. George, UT to Garden City, UT spans approximately 320 miles, covering a diverse cross-section of Utah's iconic landscapes. The route follows I-15 north to US-89 east, transitioning from red rock deserts to alpine forests. This journey is not just a drive; it’s a journey through geological time, with formations ranging from 270-million-year-old Kaibab limestone to recent glacial deposits in the Bear River Range.

One notable fact: The section from Beaver to Cove Fort follows the Old Spanish Trail, an historic trade route used in the 19th century. The drive takes about 5-6 hours without stops, but plan for 8-10 hours to explore the many attractions. For those wondering how to find the best stops and hidden gems between cities, this guide provides a curated list.

The primary highways are I-15 and US-89, both well-maintained with ample services. Gas stations are frequent along I-15, but from Nephi to Garden City, stations become sparse. Plan to refuel in Beaver, Nephi, and Logan.

• Fuel costs: As of 2025, gas prices average $3.50/gallon. A 320-mile trip costs ~$50 for a typical sedan.
