'''Calleva''' is the largest outdoor education organization in Central Maryland, United States, established to provide outdoor team building opportunities, host summer camps, and take groups of individuals on excursions throughout Maryland,<ref name=":0">{{Cite web |last=Moeller |first=Amy |date=2023-02-03 |title=10 Fun Outdoor Summer Camps in the DC Area |url=https://washingtonian.com/2023/02/03/fun-outdoor-summer-camps-in-the-dc-area/ |access-date=2024-08-05 |language=en-US}}</ref> Virginia,<ref name=":0" /> North Carolina, West Virginia, Delaware, Colorado, and Canada, among other places.

==History== Calleva was started by Nick, Alex, and Matt Markoff, whose family was involved in the summer camp business for generations, including close ties to Valley Mill Camp. In the fall of 1993, in order to raise capital, they held the first ever Markoff's Haunted Forest.<ref name="lha">{{cite news |last1=Hayes |first1=Laura |title=One Hour Away From D.C. is One of America's Most Intricate, Long-Standing Haunts |url=https://washingtoncitypaper.com/article/194000/one-hour-away-from-dc-is-one-of-americas-most-intricate-longstanding-haunts/ |access-date=22 December 2020 |work=Washington City Paper |date=27 October 2016}}</ref> Camp Calleva began in the summer of 1994.<ref name="gne">{{cite news |last1=Chadwick |first1=Melissa A. |title=Calleva puts a little adventure in summer |url=http://www.gazette.net/stories/072606/bethnew195758_31953.shtml |publisher=Gazette.Net |date=26 July 2006 |archive-url=https://web.archive.org/web/20110522185009/http://www.gazette.net/stories/072606/bethnew195758_31953.shtml|archive-date=2011-05-22 }}</ref> The word Calleva means "where the paths cross".

They offer LIT (Leadership in Training), Cubs (ages 4–5), Explorer (ages 6–8), Adventure (ages 9–14), and High Adventure (ages 15–16) programs during the summer, as well as various other outdoor excursions throughout the year. The Calleva Ski Club was offered during the winter, but stopped in early 2020 due to COVID-19 and resort management changes.

In 1998 the first ever Calleva Challenge was held, a triathlon of sorts on the Potomac River. This was later renamed the Potomac Challenge in 1999.
