Hand-picked from the full list below, with the reason each one earns a trip.
Amite River Valley
East Baton Rouge Parish
The Amite River near Baton Rouge is Louisiana's most productive agate locality, its gravel bars carrying banded agate, carnelian, jasper, and even the rare local opal.
East & West Feliciana Parishes
East Feliciana Parish
The Feliciana parishes sit on some of Louisiana's best exposures of the gravel-rich Citronelle Formation, the source rock for the state's agate and carnelian.
Pollock
Grant Parish
The gravel-capped Kisatchie Hills around Pollock shed agate, jasper, and petrified wood, including palmwood, into the road cuts and creek bottoms of the Catahoula Ranger District.
Ouachita River
Ouachita Parish
The Ouachita River carries agate, petrified wood, and opalized wood south out of the Arkansas uplands, dropping them on gravel bars around Monroe in north Louisiana.
Old Pearl River
St. Tammany Parish
The Pearl River system on Louisiana's eastern edge reworks Citronelle gravels into agate, carnelian, and petrified wood, giving the southeastern Florida Parishes their own collecting water.
Tangipahoa River & Streams
Tangipahoa Parish
The Tangipahoa River near Amite City draws agate, carnelian, and jasper from the same Citronelle gravel belt that feeds the Amite, and its LA 16 crossing is a long-known access point for collectors.
