The mountain bike trailhead for the Deerhead Lake Trail is found off Birch Creek Road from turn out of US15 at Apex North of Dillon. Look for it on the right at junction marked primitive road 2 3/4 miles along Birch Creek road above turning to CCC Camp. The trail leads 7 miles to NFS Dinner Station CG.
Keep right to start and cross a small creek (a good place for spotting moose). A junction in the road can provide a worthwhile detour to Bond Lake, return to take the other junction which winds up at Deerhead Lake. A good spot for fishing and seeing elk, deer and even bears who eat the many frogs here. The trail is rocky in places, especially near the top.
Return by backtracking down the trail for 1.5 miles and take the trail marked NFS Dinner Station CG on the right-this is a narrower and steeper descent and provides adequate excitement as you dodge trees at speed.
Overall, Deerhead Lake Trail is the 38th most popular mountain bike trail of all 63 mountain biking rides in Idaho.
