Hilo’s coastline hides some of the Big Island’s clearest bays, and this relaxed half-day tour takes you to two of the best without the crowds. You’ll start with a short nature walk where your guide shares cool facts about Maunakea’s lava tubes that feed cold freshwater into the ocean, shaping the land and local culture along the way. Easy stairs lead down to the first bay for about an hour of snorkeling – turtles often glide by while smaller fish dart around the reefs. Snacks on the beach recharge you before heading to the second spot, reached by a sandy path to a bay bursting with colorful coral and sea life (fewer turtles, more vibrant underwater gardens). Another hour in the water with your guide keeping watch, then a comfortable ride back. Gear included, small group – just a peaceful, guided way to see Hilo’s hidden marine world up close.
