Decode clues and uncover secret sights during these three scavenger hunts

Best for Word Nerds and Puzzle Pros

Lexicon Lane

925 13th St., NW

Head to the third floor of the language museum Planet Word to find a life-size “village” filled with clever wordplay. Choose a challenge from more than ten cases with themes such as Greek mythology and Slavic folklore, then use the clues scattered around the tiny town to tackle word-centric riddles and mysteries. Cases vary in difficulty and cost $30 each. Puzzlers must be 12 or older, and groups of up to four are recommended.

Best for Curious, Outdoorsy Kids

Nature Scavenger Hunt

3400 Bryan Point Rd., Accokeek

Explore the flora and fauna of Piscataway Park on this self-guided adventure that encourages observation. Rather than providing clues to decode, this hunt focuses on broad prompts such as finding “what you think a bird sees” or “something you think is gross,” allowing kids to identify their own objects of interest. The Accokeek Foundation, one of the park’s stewards, publishes the list on its website for $1, or you can pick up a copy at the visitors’ center. Access to the park is free.

Tickets are $18 to $24.

Fossil Hunting

Lawyer by day and fossil hunter by night, Christopher Barr has been researching ancient wonders in DC’s architecture for more than 20 years. Here are three places he has spied traces of past life.

Ancient Crinoids

Shallow Sea Creatures

2121 Pennsylvania Ave., NW

Description: A variety of tiny skeletal structures from creatures that once lived in a shallow sea

From: The Mississippian Period, 350 million years ago

Nautiloids

Fourth St. and Constitution Ave., NW

Description: Shells of nautiloids, a type of marine mollusk
