Honolulu is an indoor play hall inside the Galeria Metropolia mall, with multi-level climbing structures, slides, sledge-style slide tracks and ball pits. The climbing structure is aimed at kids over 3; younger ones play with a parent alongside.

Play staff keep watch, kids can't leave the hall on their own, and parents can join in or sit in the café. It has its own toilets, separate from the mall's.
