At a glance, there is an "entrance fee" to drive up to the top of Mt. Evans ($10) unless you have a National Parks Pass.
However, upon further digging, I found that some people dispute this fee, and that the "official rule" is that if you don't use the Forest Service Amenities, you shouldn't have to pay. The contention is what defines "Amenities"... (The Scenic Pullouts is probably the only one I need to use) I have not found any additional/recent information.
So, for the locals, what is the reality/law? On an upcoming road trip, I plan to drive up there for a quick look, and perhaps snap a photo and be on my way. Do I really need to pay $10?
The thing is that I have a national parks annual pass, but it expires the end of this month...and my current plan is to drive up Mt. Evans on June 1.... I may rearrange my plans a little and go up Mt. Evans on May 31 instead and go to Pike's Peak on June 1...
