Another Side of San Diego Tours offers Southern California Whale Watching at its finest. We provide multiple whale watching trips daily departing from San Diego. We offer whale watching tours year around. December through April is the prime Grey Whale migration period. San Diego is ideally positioned to take advantage of the annual Grey whale migration, which brings thousands of Grey Whales along the coastline and within minutes of San Diego Bay. May through November brings warmer waters and the opportunity to view blue whales up to 80 feet long, finback whales, huge pods of dolphin that number in the thousands, seals, sharks, and many other marine creatures. Another Side of San Diego Tours whale watching cruises are a great experience for families, churches, and companies with a universal appeal to all ages. Join us on one of our semi-private cruises or charter one of our boats for just your private tour group or corporate event.
