On our Thanksgiving trip to Dry Tortugas National Park, we decided to stop in at Everglades National Park and, because it is only 30 minutes east of Everglades NP, we shot over to Biscayne NP too so we could stamp our passports and get a basic firsthand impression of the place.
National Park Passports
Since it is the 100th anniversary of our national park system I was reminded that you can get a “passport” to the national parks. When you visit a national park, there will be a cancellation station in at least one of the visitor centers where you can stamp your passport with the date of your visit. Cool!
