Description

Home of some of the hardest routes in the Douglas State Forest, a few of which are easily into the double digits. This is a massive boulder with a huge, twenty degree overhung, laser cut face.

Getting There

After passing Basin Marsh Trail, walk another minute or two, where you will walk up a small hill. The trail flattens out for a bit and then goes down a small gradual hill. Before going down the hill, look to the left. You should see a rocky area. The tallest of which is Coffee Block. Walk through the brush to Coffee Block and you should see the Impossible Boulder just a bit further off trail in the same direction (about 60 meters off trail in total)
