From CBSN Denver:
"The Keep Colorado Wild Annual Pass offers vehicle owners a reduced-price annual state park pass when they register their vehicles. It’s one of two new state laws that go into effect Tuesday that allow more access to Colorado State Parks.
There are 11 state parks in Colorado that draw 11 million visitors each year. The parks offer camping, fishing, hiking, hunting and other outdoor recreation.
Park officials say they are being “loved to death” by the growing popularity of Colorado’s state parks. Currently an annual affixed vehicle parks pass costs $80. While the price of the Keep Colorado Wild Pass has yet to be determined, it’ll be no more than half the current price, so no more than $40. The price can drop depending on participation, with a goal to achieve a $20 price with high participation rates."
