Everything was great! I booked the tour 30 minutes in advance and the staff was extremely helpful answering questions and being patient with a few late arrivals. Having booked the excursion so quickly, I never read the part that closed toe shoes were needed but they were prepared and had shoes available that we could use.
Our guides Kanani and Maikalani (Dylan) were amazing and it was heartwarming to hear olelo hawaii (hawaiian language) added into the tour. They were extremely good at reassuring some of the children on the trip that there's no need to be scared and provided us with some yummy snacks along the way. The plant knowledge that was brought into the tour was also a plus. Our driver Pono was also great, from transport to helping us on the final 1/2 miles line.
Highly recommended!
