The Annual Flower Trial Garden is a devoted horticultural research garden on the campus of Fort Collins' Colorado State University, open to the public throughout the year near the campus' Center for the Arts. The garden strives to serve as a trial space for the performance of annual plant cultivars in the region's high-altitude Rocky Mountain environmental conditions, with primary annual plantings on display between late May and mid-October. Plant varieties are grouped by genus and arranged by color, with more than 1,000 different cultivars typically on display each year. In addition to the main annual showcase, the garden also presented an annual pansy display, which is planted in fall and on display through the early spring.

Coloradans are outdoor enthusiasts, and one of their beloved hiking spots is Hanging Lake. The Hanging Lake Trail sits off Interstate 70, just 10mi (16km) east of the town of Glenwood Springs.

Hanging Lake is a unique geological feature, complete with a stunning hanging garden.

Admission into the Bishop Castle is completely free. It’s important to note that people live and work in the Bishop Castle, so be mindful of that while exploring the Castle.
