@Kendall James-VargasThank you for the link for Juneau! The regular national park pass is a yearly pass and only covers entrance fees. The senior pass is a lifetime pass for anyone over 62, which I think now costs $80. Besides free park entry, it is also good for discounts for some park activities charging a fee (not all), and camping fees for the parks, Corps of Engineer parks and some other federal lands. Some states also accept the Senior pass for their state parks camping.
