Where to Find Agate in Oregon
Oregon is the most varied agate state in the country. The Priday Ranch and Richardson's beds near Madras yield blue, plume, and moss-filled thundereggs from welded tuff. South of there, Glass Buttes in Lake County hosts flame-colored chalcedony with sagenite inclusions, and the Owyhee plateau on the Oregon-Idaho border produces the famous Owyhee blue agate and Morrisonite-style picture jasper. The central and southern Oregon coast (Agate Beach, Yachats, and the Coquille River mouth) yields tide-tumbled carnelian, banded agate, and small chalcedony nodules in winter storm gravels. Each district produces a recognizable color and habit.

Standout agate spots in Oregon
Hand-picked from the full list below, with the reason each one earns a trip.
Agate Beach
Lincoln County County
Agate Beach is named for the agates found along the Newport and Yaquina Head shoreline, and Oregon Sea Grant notes that winter storms expose the gravel beds that supply beach agates. The site stands out because Oregon ocean-shore rules allow small noncommercial collection of agates and other nonliving natural products, making the access as important as the material.
Beach Area Yachats
Lincoln County County
The Yachats beach area sits on Oregon's central coast, where storm-reworked gravel can expose agate, chalcedony, jasper, and related beach material. Its strength is broad legal ocean-shore access for small noncommercial collecting, paired with a shoreline that is repeatedly refreshed by Pacific winter wave action.
Succor Creek General Area
Malheur County County
Succor Creek is a remote canyon locality where Oregon State Parks identifies a haven for rock hounds and DOGAMI lists agate, jasper, and related chalcedony-family material from the area. Its standout quality is the combination of high-desert volcanic scenery and collectible silica materials, including jasper, chalcedony, chert, and opalized wood.
