Percé Rock (Rocher Percé), within Île Bonaventure and Percé Rock National Park in the Gulf of St. Lawrence just off the tip of the Gaspé Peninsula, is one of the most recognized natural attractions in Canada. Rising abruptly from the sea and often dramatically changing color as light and weather conditions vary, the rock, which is pierced by a large arched opening, presents a spectacular sight. Measuring 433 metres (1,420 ft.) long by 88 metres (288 ft.) high, it is a tall calcareous block experts speculate was formed on the bottom of the sea during the Devonian geologic period.
Note: Visitors are strongly advised to refrain from walking alongside Percé Rock and Mont Joli; frequent rock slides and falling debris make these areas extremely dangerous. Pets are not permitted.
