The first zipline is very very short and easy, but you quickly escalate to massively long and very high lines. One of the good things about this setup is they have tandem lines so I could go next to my wife. The guides were fun but professional. My only complaint is not about the ziplining, but about transportation while leaving the park. Unless you drive, expect to take a public bus/ferry back, which takes at least an hour and a half (vs. 20 minutes for a direct shuttle).
