If you have kids in Hawaii, one of the best places to take them to play are the beautiful tidal pools found all over the state. On the North Shore of Oahu, Shark's Cove is a great spot I remember going to as a kid. There are tons of tiny sea creatures to observe and play with, including tiny cuttlefish, reef fish, and sea cucumbers.
Now that I live on the Big Island, one of my favorite beach spots is O-TECH. There's a great little area where kids can play in shallow water and look for all kinds of treasures. Make sure you keep an eye on the ocean though, because if big surf is coming in huge waves can come crashing in at any second to pull you out to sea.
If you're fortunate enough to be in Kona during sunset time, you're in for a show. Our west facing coastline boasts some of the most spectacular sunsets you'll ever see.
