Yankee Boy Basin is an alpine basin in the Uncompahgre National Forest of Ouray County. From mid-July to early August, the basin offers spectacular wildflower displays. Country Road 361 (high-clearance vehicles recommended) runs from the town of Ouray to the basin. At the basin the road turns into a hiking trail that leads to Mt Sneffels (14,150 feet), the fourth tallest peak in the San Juan Mountains.
