It all depends on your preference. Both the morning tours and the afternoon tours are equally great! You will be doing the same course no matter the time you choose. Each of our tours have a 45-minute prior check-in time, so if you are on the west side (Kona/Waikoloa), it will take about 1hr 45 minutes to 2 hours to get to our location. Coming from the East (Hilo) side of the island will take at least 30 minutes. So, when planning your experience and choosing a tour time, be sure to factor in the drive time as well.
