To commemorate the National Park Service's 100th birthday, I thought I'd compile a list of the National Parks that I've visited. I love lists.
I thought about including all 413 units of the National Park Service (which includes National Parks, National Monuments, National Preserves, National Historic Parks, National Historic Sites, National Battlefield Parks, National Military Parks, National Battlefields, National Battlefield Sites, National Memorials, National Recreation Areas, National Seashores, National Lakeshores, National Rivers, National Reserves, National Parkways, National Historic and Scenic Trails and National Cemeteries), but instead I'll save those lists for another day (and I had no idea there were so many different units).
Marked in bold are the parks that I've visited.
As of 8/29/16 I've visited 23 of the 59 National Parks. I've got some work to do!
Black Canyon of the Gunnison
Gates of the Arctic
Great Sand Dunes
Great Smoky Mountains
