St. John's is a destination that most visitors will remember for its strikingly vast coastline, colourful buildings and remarkable Newfoundlander energy. St. John's is located on the far eastern tip of the Island of Newfoundland, and its location has made it a popular destination among explorers, pirates and, more recently, cruise lines. St. John's is Canada's oldest city and was first discovered by European explorers in 1497, when John Cabot sailed into the harbour of modern-day Bonavista. While in St. John's, enjoy long walks, seaside picnics and exceptional birdwatching opportunities along the rocky beaches. Because of its rich history, St. John's abounds with historic sites. One that is a must see is the Cabot Tower at Signal Hill National Historic Site, St. John's most visible landmark. Along the beach of Petty Harbour, weathered boats, wharves and intriguing sheds on stilts can be found. Offshore, whale watching and personal boat tours are available to the public.
