Those 62 or older can still squeak in under the deadline to snag a bargain before the price goes up for the lifetime Senior National Parks Pass. August 27 is the final day to get yours in person or online at the $10 price; after that, it goes up to $80. The pass is good for the lifetime of the holder, for free admission to all national parks and many other public lands. Companions of someone holding a Senior Pass also get in for free.
Buy the pass at any national park, or online for an additional $10 processing fee. All eligible Senior Pass orders placed online before 9:59 p.m. MDT on August 27 will be processed at the $10 price plus an additional $10 processing fee. Go to https://store.usgs.gov/senior-pass to order. Print and carry your online confirmation; it will be honored until you receive your actual card.
