About this quest
Join the chase through DC’s iconic landmarks as a K.L.A.W. agent when you track Apex, N.I.C.K.’s most over-the-top thief. From the Smithsonian to the Washington Monument, uncover clues, crack challenges, and stop his wild plan involving a stolen T. rex. History, humor, and absurd spectacle collide in this fast-paced walking adventure.
Is this for you?
Who it's for
Families with school-age kids and dinosaur fans can chase a comic thief and a stolen T. rex past the Washington Monument, the Air and Space Museum and the National Archives, solving puzzles on the way. The 2.7 km loop takes a little over an hour and ends at the Natural History Museum, so it slots in between museum visits. If you want a guide-led history tour, pick something else.

Frequently asked questions
Is there a T. rex walking game in Washington DC?
Yes. This walking game is built around a stolen T. rex. You play a K.L.A.W. agent tracking Apex, an over-the-top thief from N.I.C.K., following clues and cracking challenges at landmarks on and around the National Mall. It begins at the Smithsonian National Museum of Natural History.
Where does it start and how long does it take?
It starts and finishes at the Smithsonian National Museum of Natural History. The route covers 2.7 km and takes a little over an hour, passing the Department of Agriculture, Washington Monument, Enid A. Haupt Garden, Air and Space Museum, the Gallery of Art Sculpture Garden, National Archives, Navy Memorial Plaza and FBI Headquarters.
Is it good for kids?
It suits families with school-age children. The story is a comic spy chase full of humor and absurd spectacle rather than anything dark, and the puzzles are set in what is in front of you at each stop. Very young children may find a 2.7 km walk with puzzles to solve a stretch.
Do we need to book a time, and can we pause?
There is no set time. Start whenever you arrive, on your own phone, with no guide or group to meet. You can pause and continue later, which helps if you want to step into a museum along the way. One ticket covers your whole group, up to the stated number of devices.
Is it played outdoors?
Yes, the game is played outdoors as you walk between landmarks, so dress for the weather. Because it begins and ends at the Natural History Museum and you can pause at any point, it is easy to combine with indoor museum time if the weather turns.
Is The T.Rex that Vanished from Washington: a KLAW vs NICK Mission self-guided?
Yes. The Questo app guides you between locations without a tour guide or fixed departure. Start when it suits you and pause if needed.
