From Johnson Lake, the mapped loop follows Johnson Lake Trail to Timber Creek Trail, then descends through the drainage back to Baker Creek Trailhead. The final leg closes the circuit, but it is still a remote route; carry enough food and water for a full day. Potable water is not available along Baker Creek Road, and the trailhead restroom is a pit toilet without running water. The approach is the 3.5-mile dirt-and-gravel Baker Creek Road from NV-488; park only in designated spaces, not along the road. Winter and spring weather can close the road, and snow can make high-country navigation difficult.
Pets are not allowed on park trails, except trained service animals. A free backcountry permit is required for overnight camping. Fires are prohibited above 10,000 feet. If you want a shorter outing, the separate Johnson Lake hike from Snake Creek is about 8 miles round trip; it reaches one lake and does not follow this loop.
