Centennial is a tiny mountain town west of Laramie, sitting where the plains start climbing into the Snowy Range. The town itself is only a handful of streets, but the setting is strong enough to carry it.
In summer and early autumn, the reason to come is the Snowy Range Scenic Byway, which climbs past lakes, trailheads, and high granite views toward Medicine Bow Peak. In winter, Snowy Range Ski Area keeps the town useful after the high road closes.
Centennial is not a resort town in the polished sense. It is a base camp with a few places to eat, a small museum in the old depot, and immediate access to Medicine Bow National Forest. If you have a spare day in Laramie, this is one of the easiest ways to trade cafe time for mountains.
