Summit County, Utah

Summit County is tucked into the northeastern corner of Utah. It’s a place of contrasts, where Park City’s glitz rubs shoulders with ranching towns like Coalville. Ski resorts draw crowds in winter, while summer brings hikers and mountain bikers looking to explore the mountains.

The Uinta Mountains loom large here. They’re the highest range in Utah, no joke. Water is a big deal, too, with the Weber and Provo Rivers beginning in these parts.

Visitors can explore the remnants of old mining towns, but Summit County isn’t all about the past. The Sundance Film Festival brings Hollywood to the Rockies every year, adding another layer to this already interesting mix. That’s Summit County for you.
