A few stamp questions.
What is a national park passport stamp?
A cancellation stamp is an ink impression that records the park and your visit date. Collectors add these to a passport book as a keepsake of their travels.
Are the ink stamps free?
The cancellation stamps are free. A passport book is a separate purchase, and normal park admission or other visit costs may still apply.
Where should I look for a stamp?
Start with the park's official stamp information or ask a ranger. Some parks have several stamping locations, and seasonal facilities may have limited hours. The stops below are a starting point, not a complete list.
What if I forgot my passport book?
Bring a small piece of paper to collect the ink impression and add it to your book later. Some parks also publish printable stamps; check the individual park's website for its options.
