Great tour of West Magnolia starting at the High School, which is also the last stop of the Boulder-Nederland N Bus.

This route gives a great tour of West Magnolia, starting from Nederland high school. There's some flowy sections, some very rocky sections, a few hard-to-find turns, and a whole lot of fun.


The Boulder-Nederland N bus is a great way to get your bike from Boulder to Nederland. On Saturday mornings in the summer, 30 or so mountain bikers load their bikes in the luggage section of the regional bus and head up the hill. Here's an option for a loop starting at the last bus stop in Nederland, or plan on riding back to Boulder. But don't be fooled—there's no route "down" that doesn't involve at least 1,000 ft of climbing!

From the Nederland High School parking lot, head to the east end and start on the Sugar Magnolia #926 trail south. This trail is a bit steep and very rocky. At the first intersection, take a hard right onto Aspen Alley Trail #342A and follow it west to Lookout Trail #926, accessed across the jeep road to the south. Lookout Trail #926 ends on a jeep road, make a left and follow the road to the metal gate. At the gate, turn right and look for the singletrack Cutacross, which ends at the 356 Jeep road.

Cross the road and look for the singletrack marked 927—this is Hobbit 3 #927. Hobbit 3 #927 climbs for about one third of a mile, and then there will be an unmarked trail to the right, Lost Meadow Trail #355, which starts out climbing gently and then gets quite steep 0.9 miles in. At this point, there will be a fork—hang to the left and hike-a-bike up about one third of a mile.

The trail mellows out again and then you'll hit the intersection of a Jeep road. This is a tricky intersection—DO NOT follow the sign to Rollinsville! Make a left and head down the jeep road, but don't go too far! Go about a one third mile, then there will be a meadow to your right. There's a faint trail through the meadow to get you to Schoolbus. After about 20 feet, you'll see the School Bus #929 trail. Make a left and enjoy the descent! Try and stay on the skinnys to avoid riding through mining tailings. School Bus #929 ends at an intersection with Hobbit 2 #927 and Hobbit 3 #927. Stay right to get on Hobbit 2 #927 which crosses a jeep road and then continues east. Take Hobbit 2 #927 to Hobbit 1 #927 (quick right turn on Jeep road, then left on Hobbit 1 #927 ) and follow to Re-Root #927 .

Follow Re-Root #927 east (and watch for 5 alternate rock feature lines), the trail crosses the road at about the 1 mile mark, continue on until you hit the intersection with Aspen Alley Trail #342A . Turn left, climb a short way, then stay right at the next intersection (don't get on Whoop-Di-Dos (926.1F) ) and follow Aspen Alley Trail #342A back to Sugar Magnolia #926 . Take a right on Sugar Magnolia #926 and you're back at Nederland High School.

It's more than 45 degrees steep, but rollable with a clean rampy exit.  And there's a ride-around.
