Bayhorse Lake – Trealor Creek Loop

Know Before You Go!

Check weather and trail conditions before you head out. Contact information here.

The Bayhorse Lake-Treelor Creek Loop is a great 25-mile ride for ATV and motorbike riders, starting and finishing at Bayhorse Lake, a nice camping destination. Ride time is about 3-4 hours. Take Forest Road #051 from Idaho Highway 75 to Bayhorse Lake. From the lake, take Forest Road #051 toward Bayhorse then turn right on Trail #025 going south. Cross the creek, ride up a draw and climb to the top of a ridge. Watch for Trail #096, an ATV route, peeling off to the right. Take Trail #096 to a high point where you get a good view of the Thompson Creek Molybdenum Mine. Follow #096 downhill through thick timber to Cabin Creek. You'll emerge from the woods on Forest Road #385. Take an immediate hard right and climb on the road. At a ridgetop junction with #384, bear right on #385. The route contours around Second Creek. The trail drops into Cash Creek and climbs over to the Trealor Creek Road #045. Turn right on #045 and right again on Trail #159, a rough and rocky ATV route, and ride the final five miles back to the lake. Be sure to shift into 4WD low as you begin on Trail #159. You’ll come to a three-way junction at the end of Trail #159. Bear left to return to the lake. The camping at Bayhorse Lake is self-contained. No services.

Optional add: If you have time, turn left on the Trealor Creek Road #045 and ride downhill to Road #041, turn right and ride Trail #041 for several miles along Squaw Creek. Trail #041 dissolves into Trail #149. Follow that along Squaw Creek for several miles, then turn right on Trail #350 and follow that to Trealor Creek Road #045. Turn right and return to Trail #159, heading east to Bayhorse Lake and return to the lake as described above.
