Ramblewild is the largest “tree-to-tree” adventure park in the U.S. Set in the Berkshires’ sprawling forest, the 9-acre park features a series of platforms 10 and 15 feet above the ground with eight obstacle courses taking adventurous guests through various heights in the trees. Obstacle courses use zip lines, balancing logs, suspended bridges, rope ladders and more, with four courses crossing over a ravine. Kids 7 and up may climb as long as they meet the 55-inch height requirements. The adventure park is open year-round: Daily May 15 through September 7; Friday through Sunday May 1 to 14; and weekends only September 8 through April 31. Summer rates are more expensive, with kids $57, teens $63 , and adults $69.
