When I was growing up, there was one kid in the neighborhood who had a trampoline in her backyard. These days it’s hard to imagine how many kids piled on that thing, doing flips with no nets, jumping as high as we could, and trying to bounce each other off onto the ground. We certainly had a good time, but it wasn’t the safest activity. Times have certainly changed!

Sky Zone, an indoor trampoline park, with locations in Boston, Everett, and Providence is one way to experience the thrill and fun of this traditional outdoor activity in a safe manner.

With 10,000 square feet of walled trampoline courts, you can jump to your heart’s content. Picture several trampolines stitched together in a giant rectangle, with three sides or walls also made of trampolines, and you come close to what one section of Sky Zone looks like. One trampoline court has high net walls, where 3D dodge ball is played. A third small court is just for toddlers under the age of four.

All of the courts are supervised by “referees,” who watch jumpers closely and are not afraid to use their whistles or call people over for a chat about the rules. On the largest court, the trampoline is sectioned into squares. You can jump from square to square, but two people are not allowed in one square at one time. And, yes, you can literally bounce off three of the walls, which is usually the source of much hilarity.

Visiting works like this: Entry is timed by the half-hour to limit the numbers of jumpers. A 30-minute pass is $8; 60 minutes costs $12; 90 minutes costs $16; and two hours costs $18. Your pass is a sticker that you wear on your shirt. Patrons are issued special sneakers to jump in and then directed to a holding area where a safely talk is given. And don’t think this is a kids-only activity! Many parents love to come and jump around with their kids.

Special hours and events, such as dedicated times for toddlers, aerobics classes, dodge ball tournaments, and more are also offered at each Sky Zone. There’s even  a night set aside just for grownups (though adults can jump at any time, space permitting). Birthday parties are very popular here, with virtually everything from food to cake to cleanup available.
