Is there a family pass that you can buy to visit multiple national parks?

America the beautiful pass

There is a seniors America the Beautiful pass that you can get for a yearly fee. I have the disabled Access pass. Veterans that are rated by the VA as being disabled can qualify for a free lifetime pass. You do not have to be rated at 100 % to get it but you cannot be rated at a 0%. I believe 10% and above qualify but you can call your rangers stations to ask them.
