Perched high above the town of Placentia, Castle Hill offers a glimpse into Newfoundland's past, where French and British forces once battled for control. You can explore the rugged remains of the 17th-century fortifications and stand beside historic cannons while taking in the absolutely breathtaking views of the bay. For a bit of a workout, take the steep but short hiking trail that starts from behind the convenience store before the bridge; otherwise, you can drive right to the top for a more leisurely stroll around the grounds and visitor centre.
