Not just for kids, summer camp allows adults the perfect opportunity to connect, relax, learn new skills, and—most importantly—have fun. For corporate groups, campsites across North America offer everything from classic camp activities (think ropes courses, bonfires, group sports) to unusual experiences (space camp and even zombie survival camp). Here are six adult-camp options to book for your next weekend getaway or teambuilding outing.

At Camp No Counselors, teams bond over classic camp activities such as archery, ropes courses, and arts and crafts. Each retreat is customized to a group's needs and can include teambuilding activities, breakout sessions, fireside chats, and more. Camp No Counselors partners with modernized camp sites across the country in areas such as Chicago, New York, Florida, Denver, Los Angeles, plus Canada, and all-inclusive private packages include three nights of lodging and accommodations, meals, an open bar, meeting rooms with audiovisual equipment, a photographer, T-shirts, and a tailor-made selection of camp activities. Nighttime entertainment includes outdoor movie screenings, theme parties with DJs, and campfire talent shows.

Located in Kent, Connecticut, on 300 acres in the Berkshire Mountains, Club Getaway accommodates corporate groups of as many as 500. The campground, located less than two hours from New York and three hours from Boston, is available for everything from picnic and weekday outings to meetings and three-day teambuilding retreats. Daytime activities include the sporty (volleyball, tennis, waterskiing), the adventurous (bungee trampoline, zip lining), and the fun (beer hikes, "Capture the Keg"), and at night, parties with themes such as Alice in Wonderland and karaoke round out adult activities. Accommodations include lakeside cabins with air-conditioning and private bathrooms, chef-prepared meals, and a sunlit meeting space.

Groups concerned about a potential zombie apocalypse can train at Zombie Survival Camp in Ontario, Canada. The camp's activities, though applicable in the event of a zombie invasion, are actually designed to teach real-life skills for wilderness survival and self-defense. Itinerary items include "Zomjitsu," tactical yoga, a weapons course, field tactics, fire craft, and survival knots, and the camp's "Zombie Outbreak Simulation" teaches groups how to work as an undead-fighting team. The camp is mobile and can set up shop anywhere in Ontario, and its Desboro location hosts private events, as well. Customizable options range from a three-hour training session to full weekend events.

For a completely customizable experience, Camp Bonfire works with corporate groups on selecting not only activities but also campsite locations based on specific needs. Camp Bonfire has relationships with more than a dozen camps in the New York and Philadelphia regions (the camps hope to expand to New England next summer) to accommodate groups of 50 to 500 guests. Programming is designed to help groups bond, build relationships, and refresh and relax through activities such as archery, canoeing, yoga, outdoor cooking classes, talent shows, and even a custom Camp Olympics. For groups looking to fully unplug, Camp Bonfire can set up a designated "technology area" to ensure the rest of the experience is device-free, though photographers and videographers are available on site to capture the experience. Sleeping accommodations range from open-air tents to lodge-style cabins, all with flush toilets, and meals are served buffet-style. Camp Bonfire, which works often with New York-based tech and advertising companies, can organize travel to and from campsite locations.

For a twist on traditional summer camp offerings, Space Camp in Huntsville, Alabama, lets groups practice their astronaut skills. Located at the U.S. Space & Rocket Center, the camp's adult teambuilding outings focus on improving communication, teamwork, and decision making through simulated space missions. Single or multiday immersive training programs are customizable to meet each group's objectives and allow co-workers to assume "in-flight" responsibilities such as mission control operator or crew member. Lodging and meeting spaces are available, and meals can be catered or served cafeteria-style.

Set among 500 acres in the Blue Ridge Mountains in southwest Virginia, Wilderness Adventure at Eagle Landing offers groups a getaway with unforgettable scenery. The property includes ropes courses, a 900-foot zip line, a 50-foot climbing wall, hiking and canoeing options, and much more, and professional facilitators can design teambuilding activities to help teams think outside the box and foster camaraderie and trust. Indoor and outdoor meeting spaces accommodate small or large groups, and meeting equipment is provided with all reservations. Lodging options include the Main Lodge, which holds as many as 56 and includes three meeting rooms, a commercial kitchen, and a dining room, and the more intimate Sly Lodge, which holds as many as 33. Use of the property's Cedar Sauna is available upon request.
