Pass Lake

A 2.3-mile single-track loop winds around crystal-clear waters high in Keystone, offering hikers a straightforward but rocky ascent that rewards visitors with views of snow-capped peaks. The lake’s high elevation ensures temperatures remain chilly year-round, making a jacket essential even during summer months when the water is cold enough to chill a water bottle instantly. Because the area lacks plowing, the lake is primarily accessible during the summer season, though winter visitors can reach it via snowshoeing. A small parking lot adjacent to the trailhead provides easy access for leisurely hikes, photography sessions capturing breathtaking sunsets, and stargazing under dark skies. Despite occasional highway noise, the setting remains a favorite for local photographers and elopement shooters seeking dramatic mountain backdrops. The site is wheelchair accessible, accepts credit cards, and offers ample parking for those seeking a quick alpine escape.
