McKinnon Flats Perimeter Loop
McKinnon Flats is a recreational area down by the Bow River and a little southeast of Calgary. More than anything it’s a launching point for personal watercraft, but there’s trails to walk or bike as well. Nice place for a picnic too, or to take in nature.
The access road is closed to vehicles in the off season but you can explore McKinnon Flats on foot (or two wheeler) all year long. We did it late in the fall and with very few people about. No snow surprisingly, but crisp and cool. With everything covered in a delicate hoarfrost, it was beautiful and that made it all the better.
McKinnon Flats Perimeter Loop: drop down to the Bow River and back up again. Having fun hiking with Chris and Connie.
It seems there’s a number of interconnecting trails here and they can be pieced together to make a big loop. It’s all dirt singletrack and perhaps the best pace to begin is up high above the river.
The trail keeps to the top of the valley for a while, then drops down to the treed flats and then back up again. There’s nice scenery and lots of solitude. Along the way there’s interesting rock formations and remains of an old homestead to explore.
It begins off Range #274 – just drive south and you’ll hit McKinnon Flats. It’s at the very end of the road and where pavement turns to gravel there’s a place to park. Walk down the access road a bit and just beyond the entrance gate trails head off both left and right. Ahead, the road bend left and descends down into the valley.
We choose to do this loop anti-clockwise and so went right here, but it makes no difference.
The trail continues through the grass and in places it’s waist high. There’s cultivated fields to your right and to the left, the land slopes away down to McKinnon Flats. Continue on, admiring the view below of the Bow River Valley and it’s cut a deep scar across the prairie here. Listen to the birds and feel the gentle breeze.
Pass under the power lines and soon after the trail makes a hard left and almost doubles back on itself. The descent begins but it’s easy going. In places the slope drops off steeply to the right so don’t trip or fall off your bike here. If icy, it could be a nasty stretch.
There’s several offshoot trails, but keep to the highest one which will eventually get you above the rock formations. Pass the remains of several fences, and these are connected to the homestead spoken of earlier. There’s more interesting remains to come.
Drop down to hoodoo like formations of sandstone and wander about. These were sculpted by time and the elements – it’s all pretty and geologically fascinating too.
Descend further and follow a trail down to the river. This waterway starts in the Rockies, passes through Calgary along the way and then joins up with the Oldman River in Southern Alberta. At that confluence they become the South Saskatchewan River. The fishing’s good on the Bow and it’s used a lot for recreation.
A side-channel makes a nice lunch or rest spot. This area along the river’s edge was the site of an archaeological dig a few years back. “As a result of the 2013 flood…a ten metre strip from the front of the site’s river terrace was removed, leaving a 400 metre exposure in the river bank that contained cultural evidence.” – Albertashistoricplaces.com.
They found bison bones and fire pit remains, among other things. These flats were a nice sheltered spot to set up camp and probably used often.
At the parking lot and boat launch, turn left onto the road and follow it for a bit. But first, spin back towards the river and take in the view. Where as the north side of the valley (here) is grassy, the south slope seen across the Bow is heavily forested and the terrain quite a bit steeper.
Just before the road bends left and begins heading up, turn right onto the trail. In moments pass the remains of the McKinnon’s LK Ranch. There’s an old tractor here and the stone foundation of a barn. An orderly line of shrubs mark the location of the farm house.
The ranch dates to the 1890s but the buildings once located here were a few years newer. While the property has been used for recreation since the 1980s, this group of buildings stood until recently. Fire did in some of them.
The old tractor used to be hidden away in the bush, but was put on display close to the homestead site. Take time to explore and imagine what used to be.
The McKinnon’s had extensive land holdings and raised 13 kids in their spare time.
The trail starts climbing but never too steeply. There’s a couple others branching off to the left (up) but keep to the lowest one if you went to follow our route. Once a little higher, look back to old homestead site and you’ll know why the McKinnon’s settled here. It’s gorgeous down there among cottonwoods and so peaceful.
The slopes along here are a mix of natural grass and with occasional shrubbery. At a draw turn left and head up. A trail continues straight on along the slope, but it must dead end later. Once at the top, the trail bends left (west) and like earlier, keeps to the valley lip next to cultivated land. Rocks removed from those fields are piled near the trail in places.
Stroll along in the deep grass and look down at the river below. It’s just so nice…and near the city yet. The trail soon arrives back at the access road, and from here it’s a short stroll back to the car. It’s a pleasant little hike (first time for us) with some nice scenery. We really enjoyed our time here and hope you do too.
Till next time…
