Overnight Expeditions
A version of our popular SumMAT Day Camps designed for more mature audiences, Petra Cliffs’ SumMAT Overnight Expeditions take campers further afield, venturing out to places like Weybridge Cave, Falls of Lana, the White Mountains, the Adirondacks, and more. Much like day camp, each trip begins and ends at Petra Cliffs Climbing Center in Burlington, where you meet your trip leaders, pack the van together, and set off on an adventure!
Is your camper age 6 to 14 and ready for an adventure closer to home?
