Arizona’s Pima County has begun accepting proposals from prospective park operators interested in running and managing Colossal Cave Mountain Park.

Citing declining attendance and other concerns, the Pima County Board of Supervisors put out the call for a new operator on March 23rd, 2015.

The 2,700-acre county park includes its namesake, Colossal Cave, as well as historic buildings, a campground, hiking trails and environmentally sensitive riparian habitat.

First discovered in 1879, Colossal Cave is about 3.5 miles (5.6 kilometres) long. What makes it special is that it is considered to be the largest “dry” cave—its water source has disappeared—in the United States.

The initial contract, for the “operation, repair, rehabilitation, development, design, construction, and maintenance of an historic show cave and nature park attraction activities,” is for 10 years and may be renewed for 15 years and 25 years after that.

For more information view Pima County’s Request for Proposal or attend the pre-bid conference at 10:00am on April 1 in the Economic Development and Tourism eighth floor conference room, 33 N. Stone Ave., suite 830.

Proposals can be mailed or hand-delivered to Pima County Department of Economic Development & Tourism, 33 N. Stone Ave., Ste. 830, Tucson, AZ 85701.

Prospective operators have until 4:00pm on May 8 to submit their proposals.
