Q: For a summer trip to Seattle, do you know of any whale-watching cruises? J.D., Sewell
A: Prime time for whale watching in the Pacific Ocean near Seattle is March to May, when gray whales and humpbacks migrate between Alaska and warmer waters. Other times, the area's orcas, also known as killer whales, get most of the limelight.
The Seattle Aquarium sponsors orca-watching trips from June to August, with June considered the choicest month. The eight-hour journeys depart from Anacortes, north of Seattle, and shuttle buses are available. The program includes educational instruction before the trip, and a naturalist is aboard. The trips cost about $60.
For details or reservations, write Seattle Aquarium, 1483 Alaskan Way, Pier 59, Seattle, Wash. 98101, or call 206-386-4320.
Among Seattle outfits that offer trips during the migration period are Westport Whale Watch, 206-268-9144 and Whales Ahoy, 206-268-9150.
Along northern Puget Sound, Western Prince Cruises in Friday Harbor offers whale cruises, and the price includes admission to the Whale Museum. Phone 206-378-5315.
For tourist information for greater Seattle, call the Seattle-King County Convention & Visitors Bureau at 520 Pike St., Suite 1300, Seattle, Wash. 98101; phone 206-461-5800.
