We had a blast the day we went ziplining with BIEA! Well worth the 1.5 hour drive from Kona. If you read the review and their website you know what to expect, a drive in a six wheel vehicle, eight zip lines and a stop at the Mac Nut Hut. What they don't tell you is that their staff is great, our two guides were a lot of fun and really made the day for my fiance and I. They also don't tell you about the last two zip lines or some of the amazing sights and views, I won't spill the secret but this is definitely in the top three of four things to do on the Big Island. We'll come back once we have kids or once their new more aggressive zip line course opens!
