Baker-Berry Tunnel ☑

Into the abyss you go

Open Route Map Peak: 37.841914, -122.493445

Be sure to push the button at the top to let people know there are bicyclists in the tunnel. If you hang out in one spot for too long (ie: try to grind the guardrails on the side), there are cameras in this tunnel that are actively monitored and National Parks Police will show up quickly.

If you carry enough speed, you can link this into the Bunker Road hill.
