Best between October and April due to sand and lack of shade.
Blue Cooler is part of a much larger system of trails that can form multiple loops. The trail is twisty and fast with some technical sections as you dip steeply into washes. There are a couple faint trails that break off the main trail so just watch for the signs and follow the bike tracks.
Since this is horse country, there are a number of faint side trails. Follow the bike tracks and signs, and you'll be fine.
The main parking area has restrooms and maps and is a great place to start this ride. Combine this ride with Bingo Trail W500
and Northwest Passage
for a nice long loop.
