Agate House Trail
What to Expect
Safety Advisory
Zero shade for the entire two-mile round trip — in summer, ground temperatures can exceed air temps by thirty degrees, and there is no water source anywhere on the trail.
Removing petrified wood is a federal offense with fines starting at several hundred dollars; rangers patrol regularly and they've heard every excuse.

Pro Tips
Hit this trail in the first or last hour the park is open — midday turns the exposed path into a reflector oven, and you'll share it with every tour bus group passing through.
Pair this with the nearby Crystal Forest loop to make a proper half-day of it; both trailheads are in the southern section of the park and complement each other perfectly.
Bring a zoom lens or binoculars — you can't enter the agate house structure, so getting a close look at the petrified wood masonry from the viewing area requires some optical help.
