Upper Taylor River is a 4-mile side trip off Taylor Pass. The route goes past Taylor Lake, heads west over the ridge, and into the Upper Taylor River Basin. The road is extremely narrow and tight in places as it hugs the north slope of the valley and ends near the mining tailings below Taylor Peak. The rocky route is manageable for a high-clearance 4x4 with a low-range transfer case. It is not recommended for full-size trucks. No established campsites are along the road, but a few wide spots could facilitate vehicle-based dispersed camping.
