GATEWAY TO THE SAN JUAN NATIONAL FOREST. Did you ever wish you could have the national forest as your backyard? You can make that dream a reality! This mountain property is located 1/2 mile from the San Juan National Forest which encompasses about 1.8 million acres in southwestern Colorado. Tall ponderosa pines provide shade and privacy. Water lines have not been extended to Unit 3 and there is no infrastructure in place or plans to do so. La Plata County may not issue building permits for these lots; buyer to verify.
