Seniors, this is something you want to get even if you don't have the trip planned.
Now through Sunday, those 62 and older can get a Lifetime Senior Pass for all national parks for just $10! That means you can load up your whole family and get into any national park for free if you show the pass. How much of a savings is this? The Lifetime Pass increases to $80 on Monday!
Plus, all seniors will get a 50-percent discount on camping, swimming, parking and tours with the pass.
Here's a list of places to get your pass. You can order on the federal recreation site or mail in your order, but there's an extra $10 processing fee.

Not a senior? You can buy an annual pass for $80 or if you volunteer 500 hours, you can get an annual pass for free. Those who are permanently disabled can also get a free pass. All the details here.
