Convenient little repair station located right off the Harrison Greenway Path and at the start of many great trails within Fantasy Island Trails Park. The perfect place to get your bike right before heading out on the trail.

Tucson's Clearwell Reservoir, with a capacity of 60 million gallons, is Arizona's largest potable concrete reservoir. It delivers two-thirds of the city's daily water supply. Surrounded by a nature preserve and trail systems, the reservoir went to great lengths to lessen the impact on the surrounding nature. Builders safely relocated several large saguaro cacti and installed a specialized animal fence around the construction site to keep animals out of harm's way.

The trails here are an absolute gem of Organ Pipe National Monument and take you away from the potentially more crowded areas of the park. There is something for everyone regardless of whether you want flat running, vert, technical trails, or flowy singletrack. The trail around Estes Canyon and up to Bull Pasture is well maintained and not very technical. You can make a longer run up to the summit from Bull Pasture if you want an extra challenge.
