“Proverbially "Run with the Buffaloes" on this Boulder County and CU classic.”— Tom Robson
Although the view of the tank can serve as a good indicator of your progress, the constant mountain views are what truly set this hike apart from others in the area.
Of course, this awesome hike does have a few downsides... Due to the presence of clay in the soil, moisture can make for very slippery conditions. Worse yet, the clay will stick to your shoes like glue! Additionally, there is little to no respite from the sun on this wide open trail. Plan accordingly with sunscreen and water.
Once you've reached the Teller Farms - North trailhead, join the East Boulder - White Rocks section as it runs west, then crosses Valmont Rd. The trail starts off as crusher fines and maintains a width of about 5 feet. About 50 feet down the trail, an 11% grade for 20 feet occurs. This section often gets washed out, creating some tricky little gullies.
After about 0.5 mile, the trail crosses over railroad tracks and turns into road base dirt/gravel. Maintaining a width of about 10 feet, the trail runs along a fenced-off private lake and wetland area. After crossing the bridge at 0.9 mile, the trail begins to open up into prairie land. At this point the trail is on a slight uphill grade. After another 0.25 mile it reaches the base of a hill with two cottonwood trees that provide shade on hot days.
Continue north as the trail winds its way up the hill. After a 90 degree right-hand turn, the trail swings back, headed north as it parallels W Phillips Rd. At approximately mile 1.75 the trail heads directly east, diverging from the road, contours slightly, then heads north as it drops into a small wash. Follow the general contours of the wash as the trail winds north, eventually meeting with East Boulder - Gunbarrel.
Turn left onto East Boulder - Gunbarrel, and head west, uphill to the famed tank. This section rolls through a grassland ecosystem and proves to have some of the best views of the front range, Longs Peak and the Continental Divide.
Once at the tank, head back the way you came!
This trail winds through lush farmland and a riparian area. This makes it conducive to diverse vegetation. Specifically, you're most likely to encounter cottonwood trees and lilacs.
