Located north of Shoreline Drive, between Shoreline Village Drive and Linden Avenue, this park is the remnant of Rainbow Lagoon by Auditorium Park before the lagoon was filled for the Long Beach Arena. Rainbow Lagoon is designed in a traditional Japanese style with two connected islands and surrounding park with high arched "rainbow bridges." The area is turf, with accenting trees. The Hyatt Hotel built its pool deck to the Lagoon edge. Rainbow Lagoon is filled with seawater, and maintained at park level, above sea level, through pumps. The pumps and tide gates were replaced in 2004.
