For a truly unique experience, call ahead to schedule an up-close-and-personal tour of this facility, which is dedicated to seahorse preservation. Watching the small and colorful seahorses, animals that are very rare to see in nature, will excite the little ones and create a very memorable trip to the Big Island. More than 15,000 of the creatures (swimming happily in 300,000 gallons of seawater) are on display, including 17 species that have been hatched in-house. Learn about Ocean Rider's eco-friendly mission, take a gander in the gift shop, and have a stroll down the coast after the tour is over.
