From it's location, just steps from the sand on Pier Plaza, the Treasure Chest is a fun place to browse and shop from a wide range of apparel, sunglasses, souvenirs, costumes and accessories. Calling Treasure Chest a souvenir store wouldn't do it justice. Although it does have a ton of Hermosa Beach-related apparel and memorabilia, it also has beach necessities like sunblock, beach towels, hats, sunglasses and boogie boards.
