Walker Ranch Loop

Trail Meter: 

A great loop relatively close to Boulder. Don't be fooled by the moderate distance (~8mi) -- this is a tough ride due to some steep climbs. "Walker" has oft been said to be the most appropriately named of our trails ... unless you are the manimal, this trail will beat into walking at least once. There are some grueling short climbs, some grueling longer climbs, and some super gnar descents.

You can ride it either direction but I normally hit it counterclockwise to get the nice flowing singletrack descent on the backside. Going counter-clockwise, you will need to carry your bike down the stairs to South Boulder Creek. Take a look at the map at the trailhead before doing the loop, but the route is well marked. Save an hour or two for this ride depending on how fast you want to go.

Ride from Boulder on Flagstaff Road and do a Super Walker -- but be sure to bring food, water, and a jacket on this ride since it's pretty long.

Good to go! A little mud on the rolling fire road section, but everything else was perfect today.

lots of heavy new snow

Rode this afternoon; had a blast! The trail in sun exposed sections is awesome, but many places in the shade were still covered in ice... We were able to ride almost every bit of it, but there were many places I would not recommend doing so... This was tough and sometimes scary. Use extreme caution!
