It never occurred to me that tide pools could be large and permanent enough to develop coral, but the Wai Opae tide pools on the Big Island are full of sea life. When we were visiting Hawaii (February) the waves were too high for snorkeling on most of the beaches. But in a tide pool, that’s no problem; the water is dead still. Wai Opae is a residential community and they don’t want tourists parking all over their streets. However, the community has arrived at a compromise – you can part along the road leading up to the gated community and hike in to the water. It was quite a bit of trouble to get to the pools, but we saw some great fish.
