Every year, over 35,000 humpback whales join the party, gliding north from Antarctica to the warm embrace of the Pacific, where romance—and adorable baby whales—are in full swing before they cruise south again. If you’ve ever wrangled kids on a trip, you’ll relate to the mama whales sticking close to shore with their calves between September and November, taking the easy route and soaking up the safety. Just north of Byron Bay, Australia’s most easterly tip, The Tweed is gifted with prime whale-spotting lookouts, giving you front-row seats to one of nature’s best shows.
