The Thomas Mountain Trail gives motorized access to the middle of Trail #142 which is handy for those camping in dispersed areas northwest of the Little Pend Oreille Lakes or those just wanting to cutoff some of the mileage of the longer trail. The trail follows Forest Service Road 530 for approximately 5 miles, and connects to routes to Ione from the Little Pend Oreille Lakes Recreation Area. It is an easy trail to walk since there is only 800 ft of elevation change over the entire trail.
