Along Hilo's Kalanianaole Avenue there is a smattering of Bay's and Beach Parks available to the public. The snorkel here is great but in the winter it can be a little chilly. You'll find many sea turtles in the water or lounging on the side. There are a few pavilions available for use but if they're taken laying out a blanket for a picnic works well too. It is a lovely spot to spend the day and watch the ocean.
