Main trail continues to left at scenic high point. Right is fun side trip but deadends. As you continue downhill on main trail, stay right where a lesser road immediately goes left. This road is closed and has a $1,000 fine because it passes through Caribou Townsite at the bottom.

8. Begin Narrower Descent

After easy stretch, you reach a switchback where the road begins to narrow and you begin steep descent down to the town of Eldora.

9. Tight Switchback

Tight switchback is tougher for long, over oversized vehicles.

After house, turn left on Huron Avenue and continue east to paved County Road 130, which connects to Highway 119 into Nederland. As you pass through houses, please do so quietly to avoid disturbing local residents.
