The Cross Mountain Trailhead is located 2.2 miles south on State Highway 145 from the summit of Lizard Head Pass. If coming from Montrose, CO, drive south on US550 to Ridgway and turn west onto CO62. Drive west across Dallas Divide to the intersection with CO145. Drive SE 13 miles through Placerville and Sawpit to "Society Junction" where you will make a right turn to continue south on 145. (Going straight at this junction will take you into Telluride in 4 more miles.) Continue south on CO145 to the summit of Lizard Head Pass with stunning views of the summits around Trout Lake. Continue south another 2.2 miles to the trailhead parking on the right (west) side of the highway.
If coming from Durango, drive west out of town on US160. At Mancos, turn onto CO184 and head NW to Dolores. At Dolores, pick up CO145 and drive NE to the trailhead which will be 11.1 miles north from the center of Rico and on the west side of the highway.
The nearest Forest Servive CG is south of the trailhead on CO145 by 4.2 miles or about a little over 5 miles north of Rico. It's called the Cayton Campground. Here is the FS description: "Cayton Campground is 6 miles northeast of Rico on Colorado Highway 145 (part of the San Juan Skyway) 43 miles from Dolores. The entrance is 1/2 mile east of the highway on the Barlow Creek Road (Forest Rd. 578). The campground has 27 campsites, many along the river. Eighteen sites offer 50 amp RV electric plug ins. There are 16 reservable sites, 11 with electricity, and 11 non-reservable sites, 5 with electricity. Fishing is popular on summer weekends. At 9,400 feet, expect cool evenings.

There also appears to be a fair amount of at-large camping at the summit of Lizard Head Pass. In general, the farther you get away from Telluride, the easier it is to find primitive sites.
