Round trip 2.8 miles (4.6 km), moderate.

The trail climbs 300 feet up a forested hillside. At the junction, veer right (west). You reach Lost Lake in 0.2 miles (0.3 km). From there, follow the trail through a ravine to the Petrified Tree parking area. From the parking lot, the trail climbs to a sagebrush meadow, descends to the Tower Ranger Station area, and then 0.2 miles (0.3 km) to Roosevelt Lodge.

If you encounter horses, move to the downhill side of the trail and remain still until they have passed.

Be Prepared to Encounter Bears

• Carry bear spray and know how to use it.
• Hike in groups of three or more people.
• Make noise to avoid surprise encounters.
• Slowly back away from any bears, for they have an instinct to chase.
