Geared for older kids (ages nine and up), Treetop Adventures Poconos is serious business. Integrated zip lines, cargo nets, high wire walks and super steep ladders make it a pretty big challenge. Kids ages six to 10 can navigate a mini version of this, called the Kids Explorer Treetop Course. They can also try the Soaring Camel 4000′ Twin Zip Flyer (kids must be accompanied by an adult; it’s the longest in PA!), side-by-side racers that look like swings; and a mountain steel-track coaster that flies through the Poconos. Advance tickets for the obstacle courses are recommended and both adventure courses require an adult guardian.. The adventure course is $50. The kids Course is $40. The 4000′ twin zip is $46 and the Mountain Coaster is $17.

The four-story Ropes Course is one of the first things you’ll see when you pull into the parking lot. It’s really high! Kids work their way through criss-crossing balance beams and bouncing bridges to see if they can make it to the top, where they’ll find the most precarious obstacles. It’s also totally cool to hang on the lower levels and take different pathways. Kids must be at least 48 inches to climb solo, or 42 inches to venture out with a parent. Don’t skip the recently added Soaring Eagle Zipline ($6/rider), which offers a stunning view of the park from 130 feet up before a 700-foot ride along the line. Entry is included in admission, which starts at $44.95 for visitors over 42 inches.

If you’re spending a day at the ever-expanding Turtle Back Zoo, take a cue from the monkeys and spend an hour or two climbing in the trees. The aerial obstacle course is massive.

Kids will make their way through 15 obstacles, like tricky rope cargo nets and wobbly balance boards. The adult course (open to anyone over 54 inches tall) is double the size with 30 elements and three times as high at 35 feet. Kids will also love the zip line (min. age 6), which lets them soar at 40 feet high over the length of a football field. They need to be over the age of six and at least 80 pounds to give it a try. Reserve in advance (especially on busy summer weekends!). The adult course is $30, the junior course is $20 and the zip line is $15 (discounts available by package.
