Mariposa Rockin’ Tailgate Swap

Free!  Free!  Free!


On Saturday, October 20th, the Mariposa Gem & Mineral Club will host the 6TH annual Mariposa Rockin’ Tailgate Rock Swap from 10am to 5pm at the Mariposa County Fairgrounds parking lot. 

Once again, the Mariposa County Chamber of Commerce is having the Mariposa Yosemite Hot Rod Custom Car Show inside the fairgrounds the same day (also FREE!), so there will be more than just rocks going on!!

This is a free community event that allows anyone and everyone to bring their rock, mineral, jewelry, or lapidary related items to sell or trade. 

Rocks, gems, minerals, rough, fossils, lapidary supplies, beads, jewelry, tools, equipment, etc! 

This is an informal tailgate/swap meet – bring your own tables/chairs/shade etc.

Please email any questions to or call 209-742-4234.
