Just came back from CDO the other day and visited Dahilayan Adventure Park. Did the 850metre asias longest zip line so they claim and it was not bad. it was 600 pesos for what seemed like a 2 minute thrill over pine forest. It was not a bad experience but I think I will stick to trail bike riding instead. They had the Luge and ATV rides but I decided against that after reading the waiver which you must sign. The track was only 3 km long and would be over in 15 mins or so...but you are not allowed to race, and each flip or rollover costs 500 pesos a pop. It's 650 pesos for newer bikes or 500 for crappy old ones. There were also horseback riding.....we then decided to go with kagayan a white water rafting specialist which cost 1000 pesos per person for a 4 hour trip. Getting there takes 30 mins each way with 3 hours or less depending on how fast you paddle for a fun filled 24 class 1 and 2 rapids over 16km. I would certainly find something more challenging if there were other offerings I could find, but it was worth it.
