Lewis and Clark County, Montana

Montana’s capital, Helena, sits at the heart of Lewis and Clark County. This piece of Big Sky Country is in the middle of the state’s western half. It’s where the plains meet the Rockies, creating a landscape that’ll make your jaw drop.
The county is named after those famous explorers, and you can bet they’d still recognize some of this rugged terrain. Outdoor adventures? You bet. Hike the Continental Divide Trail or fish in one of the many mountain lakes.
If you’re into history, you’ll love exploring the old gold mining towns. Helena itself is a quirky mix of Old West charm and modern state politics. Locals swear by the hiking trails on Mount Helena, right in the city limits. Don’t miss the chance to pan for sapphires in Eldorado Bar. Trust me, it’s way more fun than it sounds.
