Onyx Cave is a 2.1 mile loop trail located near Eagle Rock, MO and is rated as moderate. The trail is primarily used for hiking and horses and is accessible year-round. Dogs and horses are also able to use this trail.
Trail leads down hill to a opening in the Earth in several places. This leads down the canyon to the several caves and caverns that are prolific to the limestone ledges in the area.The trail gets a little tough in the bottom but easily overcome the last part back up the hill to the road is a little tough. You will see various Limestone ledges with many little caches. You wonder why the Outlaws and Ancient people liked it so well,just look around. The wonders abound.
The trail lead to private land so we turned around and headed back. Maybe we took a wrong turn somewhere.
As the map showed that the trail was 2 miles long, I was expecting at least a trail. Yes, there is a nice trail to the cave, but to say there is an actual path to follow is completely wrong. After the cave, I roughly followed the line on my trail map. The best recommendation for this alleged trail is to take Daryl Dixon and a pair of hedge trimmers to cut through the wild roses.
Good place to stretch your legs if your driving sugar camp road.
