CLICK GAP. Click Gap is a pass in the southern Riley Mountains 2½ miles northwest of Click in Llano County (at 30°35' N, 98°37' W). The saddle between Hickory Bluff and Watson Mountain is crossed at an elevation of 1,386 feet by an unimproved dirt road linking local ranches. The pass rises 340 feet above Click and affords a commanding view of the more open terrain to the east. The local rolling to steep terrain is surfaced by shallow, stony soils that support open stands of live oak and mesquite.
