When paired with its sibling trail, Spring Brook North, Spring Brook South makes a great route with good variety of views and terrain.
From Dowdy Draw, you start Spring Brook with 0.3 miles of singletrack over to a 3-way intersection with Spring Brook North to your right, and Spring Brook South to your left. Which way to go? You can take the loop either direction, as both directions offer a nice climb with a twisty descent. Since this is the Spring Brook South description, let's go right!
The Flatirons Vista South trail is a relic from days past - it's an reclaimed dirt road, and as such, is wide, gravelly, and apart from the initial climb from the trailhead on Highway 93, it's flat as well.
It makes a great connecter to Doudy Draw, and also completes a loop with it's newer sibling the Flatirons Vista North Trail. You can also expect to see a fair number of prairie dogs, deer, and even coyotes if you keep your eyes open. You're rewarded with expansive views of the Flatirons, and also some of the Indian Peaks through Eldarado Canyon.
This loop trail is a great way to get away from the raw exposure of Dowdy Draw and into the trees. When it's a wet spring, the wildflowers along this section of trail are truly unparalleled. Keep your eyes peeled for grazing deer, especially at the top of the climb in the wee hours of the morning. This trail, like most in the Dowdy Draw area, has a Goldilocks kind of appeal - not too steep, not too flat, juuuuussst right. The trail isn't very technical either, with few rocks (relative to other Boulder County trails) and nice, smooth sections.
Prairie Vista Trail is a nice short section of trail that allows you to connect up to Flatirons Vista South and Doudy Draw. It is a very gentle grade, and in fact the first half mile or so is ADA accessible, so please be extra respectful of other trail users. It's also a nice warm-up, with a gentle climb along a grassy hillside that leads into the woods before connecting with Flatirons Vista South.
Flatirons Vista South is one of those trails that on the surface isn’t much of a bike trail, but has some hidden gems for those who look off the trail. The trail starts out with a moderate climb up into the evergreens. After you get into the trees the trail comes together with the Prairie Vista Trail. Stay left to continue your journey around Flatirons Vista South. Once you go through the gate, the trail really picks up character. The trail winds through the evergreens and flows downhill all the way to Doudy Draw.
Opening Doudy Draw to bikes was a huge win for cyclists a few years ago - not only because it was an existing trail west of Highway 93 to open, but also because it's a great route with good views and a wide variety terrain for the area.
It connects from the top of Flatirons Vista trail back down to it's own trailhead located off Eldorado Drive. It juntions with both Community Ditch Trail and the recently built Springbook loop along it's way.
A simple trail, really... It follows the Community Ditch from highway 93 back to the Doudy Draw trail. Trail elevation is essentially flat, and it's wide (drive a truck down the trail wide). It can be a bit rocky or rough depending on how much cow activity it's seen lately.
Yes, cows. No, they are not wild, but they know you want to eat them so give them some space if you run across one.
