Billie was amazing, sharing the culture and the stories of Hawaii and the people, the geography and the geology. The sunrise was magical and breathtaking, just be prepared for cold breeze, get warm cloths (you can always keep them in the bus when riding the bike downhill and collect them after the bike ride). The bike ride was beautiful, adventurous. Billie assured us that he is with us for our safety and the fact that we can jump in the bus while going down if wanna opt out from riding the bike was very comforting.
Overall, the experience was great, me and my husband completed the ride in 1hr 20 mins. Billie is a great tour guide, he gave us a lot of information and insights during the tour.
