Our family took the tour with Alex and had a blast. We learned so much about volcanoes and Hawaii’s geological history from him. We lucked out with the weather, catching stunning views of the Kilauea caldera, craters and ridges. The bikes were in tip top shape and very comfortable to ride. Alex and his colleague, Pretty, made sure that our group was properly fitted with helmets and safety before we got going. All in all, great ride. Highly recommend for your trip.
