Gold Country Caves, Caverns & Mines

Gold Country Caves, Caverns & Mines Overview

Gold Country

Gold Country mines, caves and caverns include deserted gold mines from the 49er era, secluded natural caverns and tunnels carved by water. Gold Country caves, caverns and mines are all uniquely interesting. Walk deep into the 16 to 1 Mine or view the 3-dimensional model of Empire Mine. Descend a towering spiral staircase or rappel into Moaning Cavern. Find the beautiful underground lakes at California Cavern. Gold panning and gemstone mining are available at several of these attractions. Most caves and mines hover around 60 degrees year round, making these underground attractions a great place to cool off on a warm summer day.

WARNING: Caves & mines can be dangerous and deadly. Please use caution and common sense when exploring caves. Don't enter caves without a light source and necessary safety equipment. Choose not to explore a cave if in doubt and stay alive.

WHITE-NOSE SYNDROME: Bat populations in the U.S. are suffering devastating losses due to White-Nose Syndrome. Learn about this disease before entering caves and see what you can do to prevent its spread.

Hiller Tunnel is located 11 miles north of Nevada City in Malakoff Diggins State Park. Malakoff Diggins is the site of a former hydraulic strip mining operation. Local streams were harnessed and used to wash entire mountains away in pursuit of gold. This process was eventually banned but not before suffering the scars that are evident at Malakoff Diggins. Tunnels were carved through the bedrock to drain the water away from the mining operation. Hiller Tunnel is the remaining accessible tunnel open for exploration. Access Hiller Tunnel via the Diggins Loop or Humbug Creek Trails. At 557 feet in length, be sure to bring a good flashlight and shoes that can get wet. The North Bloomfield Tunnel was 7,878 feet in length and has since filled with water and debris.

The Kennedy Mine is open on weekends for surface tours of the mine office, stamp mill, tailing wheels, a steam boiler and head frame.

Masonic Caves

Masonic Caves are located near the intersection of Highways 104 and 88 in the town of Volcano. These limestone caves were once used for secret meetings by Masons. They consist of different levels and vary in size and shape. Several cave openings lead into caves that honeycomb throughout the hill. The highlight is the beautiful moss that covers the cave entrances making for very picturesque shots.

TIP: Caves are accessed by walking through the yard of a private residence, which is kind of strange, but we were greeted and welcomed through by the owners. Don't be shy to walk through to the back because it's worth exploring.
