Simon, Ula, & Bula (sorry for any misspelling) were amazing. They made sure everyone was safe getting in & out of the water. Life jackets were offered as well as pool floaties to keep your legs up while you watch the mantas. Itās a little scary at first when you get to the lightboard & look down to see these HUGE creatures right underneath you but once you start to get comfortable & relax, it was BEAUTIFUL! There were at least 20 swimming right below us, they donāt touch you & you should not touch them. If youāre scared you may swim back at anytime after letting the crew know. Only got cold after 30 mins in the water so we got out & got a hot shower rinse on the boat to warm up. Donāt forget to bring a towel! We also took Dramamine an hour before & it helped with my usual seasickness on boats. Without a doubt would do again if Iām back in Big Island!
