Thomas Square is a peaceful place to take a break. Have a picnic, throw a Frisbee around or just lie on the cool grass and shut your eyes for a while.
Here's some good news. It won't cost you a thing to enter Thomas Square in Makiki. But your sightseeing doesn't have to end at this recreation and green space. Close-by attractions like Diamond Head, Aloha Tower and Ala Moana Center will finish off your day nicely.
