Crawford Lake - Rattlesnake Point

Supporting organizations that provide hiking trails is encouraged. For example, becoming a member of the Bruce Trail Conservancy and buying the Bruce Trail Reference, Maps and Trail Guide helps. The daily fee(s) we pay for admission to Ontario conservation areas (e.g. Conservation Halton) help to support trail building and maintenance.


In the Crawford Lake/Rattlesnake Point area there are several walks of various lengths and difficulties. Most of them have great views that merit carrying a camera. For avid hikers, especially those who have an interest in biology and geology, it is hard to separate these two conservation areas from one another. My favourite loop is from Crawford Lake to Rattlesnake Point and back (or vice versa) with a round trip distance of about 16 km. First, something about an outlier.

What is an Outlier?

In its geological use, the word "outlier" refers to a portion of stratified rock separated from a main formation by erosion. Many years ago a channel was cut through the escarpment in this location. On the east side of that channel is the Milton Outlier. Today part of the channel is known as the Nassagaweya Canyon where Limestone Creek (43.479705,-79.945028) flows.

Conservation Halton Website & PDF Trail Guides

As I prepared this Crawford Lake & Rattlesnake Point Walks web file in late fall 2013, Conservation Halton was reformatting its website. Some of the updated PDF trail guides and maps are available online. The Conservation Halton Hiking web page provides a summary of hiking possibilities at the various areas. Hdere are links to:
