About
Calleva Outdoor Adventure & Summer Camp Programs offers activities where participants paddle, climb, bike, camp, and take part in outdoor educational experiences. The program includes a summer camp, a full service kayaking school with kayak training programs and trips such as a Canada kayak trip, and paddle sport lessons and excursions like canoe rentals, kayak rental, and opportunities to paddle or float down the South Branch of the Potomac River. Participants can also join farm-to-table experiences, weekly Pizza Nights, community building and small-scale sustainable farming activities, equestrian programs such as horseback riding lessons, horse days camp, Saddle Club, Pony Picnics, and tiny tots, as well as nature immersion experiences for elementary age children and challenge course and team building experiences.
• Ages: 5–18 years old
Calleva Outdoor Adventure & Summer Camp Programs includes additional offerings such as Calleva River School evening and weekend classes, downriver freestyle kayaking and carving in kayaking, and practice rides for riders. Seasonal and special events include Markoff's Haunted Forest, Lights On Night at Markoff's Haunted Forest, Markoff's Christmas Farm, Farm and Forest Cubs, and school and group programs on an aerial course. The organization states that EVERYONE is welcome at Calleva and emphasizes device-free summer adventure, with dynamic and mobile programming that visits rivers, trails, parks, and rocks in Washington DC’s “backyard.”
Calleva’s mission is to get all people outdoors, providing safe, educational, and challenging experiences that promote personal growth, group cooperation, and leadership skills. Calleva was dreamed up in 1997 and was originally founded as a small summer camp, and for nearly three decades the organization has built a reputation for excellence, with the last 30 years taking the team to a wide world of adventure. The leadership team includes founders Nick Markoff, Alex Markoff, and Matt Markoff. Olympic kayakers, top tier wilderness professionals, seasoned educators, high energy camp leaders, committed conservationists, and creative trades people and artists have contributed to the organization’s success. Calleva is nationally known as an innovative force in outdoor adventure and education, and its leaders are described as highly skilled with a reputation for creatively engaging guests. Closed-toe shoes are a must at Calleva camp.
Calleva is involved in community partnerships and projects, including support for the Alice Ferguson Foundation's conservation efforts through volunteers and resources for annual cleanups in the C&O Canal National Historic Park. The organization supports Boy Scouts of America outdoor adventure activities, campout experiences, and Eagle Scout projects, and provides outdoor adventure experiences like rock climbing for City Kids Wilderness Project. Calleva has partnered with Diversify Whitewater to facilitate weekend paddlesports events and created a joint project with Fairfax County NAACP called Connecting the Community with Nature, which teaches Leave No Trace principles. The program works with Girl Scouts to create experiences aligned with scouting values and with Horizons of MoCo to create day camp experiences that include rock climbing, rafting, and farming. Calleva has partnered with Soul Trak Outdoors to expand access to kayaking, has supported Team River Runner by providing equipment, instruction, and other support, offers kayaking experiences for Wilderness Kids Alexandria, and has provided a challenge course experience for Wilderness Leadership & Learning as a kick-off to the WILL-Lead program.
