Mercer Caverns

This natural marvel, formed over millions of years, offers visitors a journey into the depths of Earth's history and a chance to witness the breathtaking beauty of stalactites, stalagmites, and other subterranean wonders.

Mercer Caverns owes its name and discovery to Walter J. Mercer, a local gold prospector. In 1885, Mercer was exploring a nearby cave when he heard the sound of rushing water. Following the sound, he stumbled upon an opening that led to what is now known as Mercer Caverns. The cave was officially opened to the public in 1885, making it one of California’s oldest tourist attractions.

The cave system itself is believed to be around 1.5 million years old, created by the slow dissolving action of water on the limestone bedrock. This geological wonder boasts a series of chambers and passages, each adorned with intricate formations of dripstone, creating a subterranean art gallery that captivates the senses.
