Rattray Marsh Conservation Area: Awesome Boardwalk Trail in Mississauga

Rattray Marsh Conservation Area

Despite living down the road, I took years to discover Rattray Marsh Conservation Area. Living in Port Credit, Ontario (a village within the larger metropolis of Mississauga), I am spoiled for choice when it comes to walking paths by the lake.

The Waterfront Trail is quite literally in my backyard, just a two minute trek down the street. There are numerous parks, limitless lake views, and extensive sections of green space. I consider myself very fortunate.

Even though Mississauga and the GTA have its share of sprawling suburbs and concrete compounds, there are lots of natural places to go walking and hiking. Rattray Marsh Conservation Area is one of the most special walking trails in Mississauga to spend an hour or so (especially if you want to stop to take pictures).

You can easily cover most of the trails in about a half hour, but it’s easy to extend your walk on the Waterfront Trail to nearby Jack Darling Memorial Park that has its own little stretch of sandy beach.

A Significant Wetland in Ontario

Wetlands in Ontario - Boardwalks on Sheridan Creek in Mississauga, Ontario

The wetlands at Rattray Marsh Conservation Area are one of the last remaining of its kind along Lake Ontario. In fact, it’s the last one on the western side of Lake Ontario between Toronto and Burlington. It spans 94 acres of protected grounds that are home to a wide array of flora and fauna.

You’ll come across swamps, meadows, and beach, all in one place. And you don’t need to worry about potentially disrupting this sensitive property as most of the trail is raised up on an extensive series of boardwalks.

Shingle Bar

Lake Ontario - Shingle Bar - Barrier Beach

It’s one of the last shingle bar marshes on Lake Ontario. So, you might be wondering, what’s a shingle bar? I had no idea before I visited. But, that’s one of the wonderful things about going hiking in Ontario. I always seem to learn something with each trip that I take.

Here’s how it all works. This shingle bar, also known as a barrier beach, formed thousands of years ago between Lake Ontario and Sheridan Creek. Smooth, flat rocks (shaped like shingles) weathered and got pushed up onto the shores of Lake Ontario over time in stormy weather.

These rocks formed a barrier that slowed or stopped the flow of water from Sheridan Creek into Lake Ontario. The water pooled and nutrients settled at the bottom of the wetlands. As plants flourished and the region attracted wildlife, Rattray Marsh was born.

The shingle bar goes through continuous cycles of forming and collapsing. Big rainstorms and rising water levels can flood the barrier. At the same time, intense thunderstorms over Lake Ontario push more rocks onto the shore, recreating the barrier. It’s quite easy to see evidence of the shingle bar down by the rocky waterfront. Take a look at the rocks for yourself!

Walking Trails at Rattray Marsh

Boardwalks at Rattray Marsh Conservation Area - Ontario Hiking in Mississauga

These walking trails in Mississauga are very leisurely and an easy walk for anyone looking to get outdoors. While the trails aren’t maintained in the winter, it’s a great place to visit all year long. The raised boardwalks are preferable over many other trails in the late winter and early spring because you won’t encounter the mud like you will at other Ontario hiking trails.

I visited Rattray Marsh Conservation Area with Justin in mid-March on a chilly sunny day. There’s one short loop trail around the “Knoll”, a geologic feature where an ancient stream created unique conditions for many plant species in different microclimates. There are a few stairs at one end of this section of boardwalk, making it a little less accessible than other sections of the trail.

The Knoll at Rattray Marsh Conservation Area Mississauga

There’s a section of the Waterfront Trail between Jack Darling Memorial Park and Bexhill Road that’s entirely up on a raised platform. At one point, a secondary trail diverts towards Lake Ontario to a very rocky beach. The views of Lake Ontario are always so pretty. It’s one of the top walking trails in Mississauga for the spectacular lake scenery right off the main path.

There are numerous other Mississauga hiking trails at Rattray Marsh Conservation Area that eventually lead to various streets in the middle of a residential neighbourhood. Most of the sections of the trail don’t loop back around, but you can walk in a bigger loop through the surrounding neighbourhood if you don’t feel like backtracking through the conservation lands.

Wildlife at Rattray Marsh

Rattray Marsh is a fascinating place to visit for bird watchers and wildlife lovers. Even in the winter, I stopped and listened to the gentle songs of the birds. I have no idea which species of birds were up in the trees, but I loved the serene sounds of nature nevertheless. If you’re seeking migratory birds, your best bet is visiting in the spring or the fall.

The wetlands provide a diverse habitat for over 200 species of birds, some that are migratory and some that live there all year long. You’ll see ducks, Canada geese, and even swans at times drifting along the shores of Lake Ontario.

The mudflats and wetlands are home to red-winged blackbirds, great blue heron, black-crowned night heron, common tern, sandpipers, and the great egret. Throughout the trails in the forest, you might spot blue jays, chickadees, warblers, and woodpeckers.

Other Practical Information

No cycling at Rattray Marsh - Waterfront Trail in Mississauga

Visitors are welcome during daylight hours (sunrise to sunset). No cycling is allowed within the conservation area. If you’re riding your bike, you can cycle through the surrounding neighbourhoods to link back up with the Waterfront Trail on the other side of the conservation area. Please keep your dog on a leash as your dog could disturb the wildlife.

What to Bring on a Hike

A proper pair of hiking shoes is an absolute must. It’s also a good idea to bring sunscreen and lots of water, too. My water bottle of choice is the GRAYL Purifier because you can drink ANY water from any source, no matter what. Water from lakes, streams, rivers, public restrooms, you name it. It’s the world’s fastest portable purifier. Get your hands on one ASAP!

Don’t forget to pack some bug spray because there can be biting bugs depending on the time of year. Even if there aren’t any signs, it’s safe to assume that ticks are all over Ontario hiking trails. Protect yourself against ticks by reading our guide to avoiding ticks on the trails.

    Why is it not allowed to cycle through Rattray Marsh? You request people keep their dog on a leash so not to disturb the wildlife, although i encounterd a woman with a dog on a leash that tried to rush-me as i passed by. Bicycles don’t rush people or dogs. (Unless there intention is to cause harm) in which there are laws for that & is a separate topic .
    As a person that relies on my bike for movement i don’t see why a irresponsible owner can have a dog to enter the park with & a responsible cyclist that operates a bike respectfully & carefully cant bike through. Don’t post comment. I am looking for answers.

      Hi Bubba,

      I am sorry, but I don’t make the rules for this park. I am a blogger who has visited the park and just reporting on what I’ve learned. Please feel free to contact Credit Valley Conservation with your concerns. Thanks!
