I couldn't find any relevant information about a store named "Waimea Bay Beach Park". It appears that this is actually a popular public beach park located in Haleiwa, Hawaii.
However, if I were to provide an introduction based on what I found:
Waimea Bay Beach Park is a stunning natural wonder known for its picturesque white sand beaches and crystal-clear waters. The park offers a tranquil retreat from the hustle and bustle of daily life, making it a perfect spot for relaxation, swimming, snorkeling, or simply soaking up the sun.
