Points of interest

  • Visit the Old Quarry Trail (Trail 23), a truly beautiful place for a hike. Start at parking lot P5.
  • The trail is divided into two loops — medium (1.9 km) and long (2.7 km) — with interpretation panels along the way depicting the geological history of Canada’s Capital Region.
    • Trail 23 also extends past the two interpretive trail loops.
    • Much of the outcroppings of rocks found in this area are what is commonly known as Nepean sandstone. Its composition includes nearly pure quartz, creating a well-cemented, dense stone which is ideal for use in the construction of buildings.
    • You can see this special stone in many of our capital’s heritage buildings, such as the 1916 Parliament Buildings, the Royal Canadian Mint, the Dominion Observatory and, of course, the Canadian Museum of Nature.
