Betasso Preserve | Canyon Loop Trail

Betasso Preserve provides a nice easy to moderate difficulty loop for both hikers and mountain bikers. Mountain bikers are required to all travel in one direction while hikers may travel in either. The direction changes for mountain bikers so over time you can enjoy it in both directions.
The trail is mostly smooth, reasonably wide, and has some nice downhill. Parts of this trail are carved into the side of a steep slope so be careful not to fly off the side of the mountain! In both directions you'll start of in descent and finish climbing. Muddy / slushy spots are often present in the wetter seasons on trail corners on north-facing slopes.

History of Betasso Preserve
Betasso Preserve was adjacent to the old town of Orodell when sawmill and mining operations began in the 1870s. Stagecoaches passed through Orodell between Boulder and Nederland daily. Most of the town of Orodell was destroyed in a fire in 1883, and the sawmills and mining were destroyed in a flood in 1894 and never rebuilt.
The Blanchard family homesteaded the area in 1912 which was later purchased by Steve Betasso who was a hard rock miner, mining gold and tungsten. In 1975, Ernie Betasso's ranch became the open space that it is today. Ernie helped oversee the Betasso Preserve open space until his death in 1983.
