|Overlooking Agate Beach|
Directions: Approximately six miles north of Trinidad on Hwy 101, exit at Patrick's Point State Park. Follow the signs to Agate Beach Campground and park by the top of the staircase. (Day use fee applies at this site).
The trail down to the beach is long and full of switchbacks, but the views are gorgeous, and the rocks worth the walk.
Winter is by far the best season for any beach combing, but I visited in August and still found plenty of agates.
You'll find plenty of the usual clear/white breach agates, as well as carnelian (orange or red agate), moss agate, and plenty of colorful jasper. I've even heard claims of jade pebbles being found, though I cannot personally verify this one.
Be sure to bring a bag to carry your pebbles in -- they fall out of pockets easily, and it's likely you don't have pockets big enough to carry everything you'll end up wanting to take home.
Happy hunting, rockhounders!
