The lifetime Senior Pass to the National Parks for those 62 and older is going to have a big price increase from $10 to $80 in 2017.
They don't know the date yet for the increase, but anyone currently 62 or older that doesn't have this needs to buy it now.
You can buy it at any National Park or online. If you buy it online there is a $10 processing fee that makes the pass $20.
SOI recommends that all members who are eligible get the Senior Pass ASAP.
