Climb & Zipline Adventure

The main showpiece of The Forge is one of the largest aerial challenge courses in the world. Boasting over 10 acres, this adventure course has five standalone Hex Towers interconnected by two miles of ziplines, multiple rappelling stations, and 299 high ropes course elements that are spread across 15 aerial adventure trails. The Climb & Zipline Adventure allows participants to glide across one of four quarry ziplines, and provides two miles of ziplines between towers, rappelling stations, and climbing elements.

Participants with physical disabilities can also test their limits, as the adventure is designed with the capability to lift participants with mobility challenges to climb up and through a level of one of the Hex Towers, and zip nearly 1,000 feet over a scenic 12-acre lake.

Kids Adventure Zone

This fun area is designed for children ages 3 to 13 years old. Kids can safely roam free without harnesses or helmets. Little adventurers can climb more than 12 feet in safety-netted structures and take on the challenges of more than 30 fun ropes course elements. There are also mini-ziplines and balance lines.
