Even if you're the sort of person who gets lost in a walk-in closet, you won't have any problems finding the Groveland Hotel. It's on Highway 120, Groveland's main street and the route leading to Yosemite's Big Oak Flat entrance. If you're driving towards Yosemite on 120, you'll spot the Groveland Hotel on your right just as you reach the tail end of Groveland's gold-rush-era downtown.
