There is a lifetime pass to U.S. national parks and recreation areas that’s available to U.S. citizens who have been medically determined to have a permanent disability. The disabilities include permanent physical, mental, and sensory impairments.
As a caregiver, you can get the pass for your child and use it whenever the child is with you. The pass is valid for the lifetime of the child, and covers everyone riding in the vehicle with him/her.
The pass gives you free access to national parks, as well as a 50% discount on camping and a discount on other access fees.
Here is information about how to obtain the Access Pass:
