Land OwnerCity of San Diego
Fireroad that runs north-south through the tunnels area. The middle is known as "cardiac hill" because it is stupidly steep.
The northern point connects to McGonigle Canyon, and from there you can connect to areas north-east like Lusardi and Black Mountain. The horse-shoe turn at the north side is also quite steep, also known as "goat wrencher".
