We have many great national parks in Colorado and there are so many others across the nation. Instead of buying a pass for the days you are going to be there, you can buy a lifetime national parks pass for only $10 if you are 62 or older.
This lifetime pass will grant you access to over 2,000 recreational areas as well...
The National Park Service is celebrating its 100th birthday this year and because of it, you will be able to get into Colorado's parks and monuments for free.
Even if you don't live within close proximity to a National Park, this could be a great reason to visit! 4th graders and their families have free admission for a while.
