Along Hilo's Kalanianaole Avenue there is a smattering of Bay's and Beach Parks available to the public. Keaukaha Beach is among them and not just a great spot for spotting sea turtles, but a great fishing spot as well. This low key beach park is off the beaten path and you are more likely to find friendly locals here rather than tourists. Please note that the water here isn't heated like some other snorkel spots on the Big Island.
