Mercer Caverns is a show cave located one mile north of Murphys in Calaveras County California. It is named after the gold prospector Walter J. Mercer who discovered the caves around 1885 and filed a claim. The caverns have a large number of speleothems, stalactites, and stalagmites. It is formed in a marble unit known as the Calaveras Formation. It also contains a large display of aragonite frostwork.

The standard tour of the cave descends 160 feet, 208 steps down and 232 up in a traverse between the natural and an artificial entrance. The cave was mapped in 1986 to a length of 3389 feet and a total depth of 192 feet. The map can be viewed on the cave's web site.

  • Beautiful caverns! Tour guide was awesome, thank you miss K 🤩. (Mind you, we went on a Thursday 2:00pm tour) Plenty of parking (but seems reduced/limited for high flow season). No line, private tour (again, probably due to time/day/season) Clean restroom. Beautiful and scenic outdoor/waiting area.
  • We've been a few times and take visiting family with School age kids. Everyone has a great time. The tour guides have always been great. I highly recommend checking out this hidden California treasure!
