The 15 best free things to do in Halifax
"Explore the forested trails and military monuments at Point Pleasant Park, located at the south end of Halifax. There, you can see old artillery batteries such as the Prince of Wales Tower, the oldest tower in North America. The park’s roots can be traced back as early as the 17th century, and the city of Halifax actually rents the site from the British Government for 1 shilling a year."
