In celebration of Waikiki's annual humpback whale season, Waikiki Dive Center is offering a three-day, two-tank dive package for $299. Enjoy the serene song of the humpback whale in the crystal-clear waters of Hawaii — you may spot one of these gentle giants while cruising to one of the area's fantastic wreck dives on the center's custom dive boat. Whale season is December through May, with February through April providing the best chance of whale concerts and sightings. And divers will have the chance to experience them up close and personal while underwater. For more information, call 808-922-2121
