Trail Overview

Castle Garden Road is located just east of Moneta. Turn onto Castle Garden Road and continue until you see a sign to the left, and then it is five miles to the petroglyph site. You will not see the site until you travel down the hill and curve to the right. This is an in-and-out, driving time depends on the driver.

Difficulty

Castle Garden Road is a well-maintained gravel road, and when you turn to go the last 5 miles, it may become a little rougher and possibly rutted or even muddy. This road could also be accessed by car if the road hasn't been affected by rain and vehicles rutting it.

History

The Castle Garden Rock Art Complex contains Plains Indian Rock Art. The Rock Art dates between 1300 and 1550 A.D. Castle Garden is also known as HOUU NECI (Holy Water) in Arapahoe.

Very easy ride. Well maintained county gravel road for 20 miles from the highway to the turn-off to the gardens. The last 5+ miles to the trail head were also a good road, but looks like it could be pretty rutty if wet.
