The San Juan Mountains are a high and rugged mountain range in the Rocky Mountains in southwestern Colorado, and is the largest mountain range in Colorado by area.The San Juan range is thought by some to have the best, most varied scenery of all. Spanning the continental divide, it has numerous jagged volcanic summits, 13 of which rise to over 14,000 feet, many lakes, waterfalls and streams including the source of the Rio Grande. Many of the well known sites are found close to a loop drive (The San Juan Skyway) along roads CO 145 and US 550, over 200 miles of dramatic, winding mountain roads. Visitor facilities are concentrated in the towns of Telluride, Ouray, Silverton and Durango, places offering an assortment of art galleries, fine restaurants, souvenir shops and stores selling Western-themed clothing. Telluride is the location of the main winter ski resort in the mountains, known as Mountain Village. Compared to other places in the Colorado Rockies further north, almost all areas of San Juan Mountains are relatively far more quiet, even though the scenery is every bit as spectacular.
