Living On The Edge Of MacTaggart: A Magrath Heights Field Guide For 2026
Step out the back gate of a house on May Common, walk two blocks east, cross a blue pedestrian bridge, and inside of ten minutes you are standing on a bentonite clay slope above Whitemud Creek with no sightline to a single roof. Magrath Heights is one of the few Edmonton neighborhoods where that sentence is literally true, and 2026 is the year it gets a little easier to prove.
Here is the claim worth holding onto: the ravine on your eastern boundary is not a park, it is a working conservation reserve that was never designed for casual foot traffic, and the city's current infrastructure push is finally catching up to the fact that thousands of you already treat it like a backyard. If you have lived here a while, this changes how you plan a Saturday. If you are new, it changes what you should pack in your trunk.
Most Edmontonians who talk about Magrath's ravine mean one of two connected pieces of land. The northern piece is Larch Sanctuary, a conservation easement held by the Edmonton and Area Land Trust. The southern piece is the MacTaggart Sanctuary itself. Together they cover roughly 257 acres co-owned by the University of Alberta and the City of Edmonton after Sandy MacTaggart gifted the land and convinced the province to donate the adjacent plot through a matching program. The welcome sign at the trailhead still quotes the previous owner, William Strait, on the point that the area "remains a sanctuary where the unspoiled nature takes precedence over people."
That sentence is not decorative. It explains almost every quirk you will encounter on the trail.
Signage is minimal on purpose. The parking lot off the south side of 23 Avenue west of 119 Street is unmarked, and the trail sits at the fork of the Whitemud and Blackmud Creeks with tree roots serving as natural staircases up the steeper inclines. The AllTrails app calls the MacTaggart Sanctuary Path a 1.5-mile loop with about 137 feet of elevation gain, taking most walkers between half an hour and an hour. That is deceptive. The elevation is honest, but the surface is not the crushed limestone you get in Terwillegar Park. It is dirt, roots, and clay.
The clay is the part outside residents underestimate. On the Larch Sanctuary loop, hikers ascend a bentonite clay hill that absorbs more water than regular dirt and becomes especially slippery under wet conditions. If it rained overnight, the boots by the back door matter more than the jacket. Runners who normally do the Whitemud Creek Trail south of here in trail shoes should expect to slow down on this stretch.
A quick reference for planning:
| Loop | Distance | Time | Surface | Best for |
|---|---|---|---|---|
| MacTaggart Sanctuary Path | 1.5 mi / 2.4 km | 30–60 min | Dirt, roots, some stairs | An after-dinner walk in dry weather |
| Larch Sanctuary loop | ~3 km | ~1 hour | Narrow dirt, clay, exposed roots | A weekend hike with grippy footwear |
| Whitemud Creek Trail (north) | 4.3 mi / 6.9 km | 1.5–2 hr | Gravel and packed dirt | Longer runs and bird-heavy mornings |
| Terwillegar Park Perimeter | 2.5 mi / 4 km | 1–1.5 hr | Wide gravel path | Off-leash dog days |
That last row matters. The MacTaggart and Larch trails allow dogs on leash only, and the terrain is not friendly to loose leashes anyway. If you want the off-leash morning, drive five minutes to Terwillegar Park instead.
One thing cyclists sometimes miss: bicycles are prohibited in significant portions of the Whitemud Creek Ravine Nature Reserve, particularly between Fox Drive and 23 Avenue, to protect wildlife and the natural environment. If you have watched a neighbor pedal into the ravine from the 23 Avenue lot, they were breaking the rule. The good news is Edmonton has better options right next door.
If you have been driving on Terwillegar in the morning, you already know Stage 2 has been chewing up your commute for years. The end is finally close. According to the City of Edmonton, Stage Two of the Terwillegar Drive Expansion is nearing completion, with the westbound Rainbow Valley Bridge open, traffic shifted onto it, and the eastbound bridge expected to be finished in 2026. For anyone commuting downtown from a home east of Rabbit Hill Road, that shortens the mental math you do before picking a school pickup route.
The more interesting change for daily life is the pedestrian and cycling infrastructure landing this year:
There is also a bike route implication worth thinking about. Because the ravine reserve prohibits bikes on the Whitemud Creek section between Fox Drive and 23 Avenue, most Magrath cyclists riding to the river valley used to have to funnel through the same handful of streets. The new pedestrian bridge network at Rainbow Valley and 142 Street gives you a cleaner exit east into the Bulyea Heights and Brookside side paths, which then connect to the river valley legally on the far side.
Once you have finished up at the sanctuary parking lot on 23 Avenue, you are three minutes from Currents of Windermere, which sits just off Anthony Henday and Terwillegar Drive as a South West Edmonton shopping and dining destination. Most Magrath residents have their standing order. If you do not yet, a few worth trying based on what the food guides currently point to in Windermere:
If you want the shorter list: Buco for pizza, Blowers for pub, Cora for brunch, everything else fills in around them.
Park at the unmarked 23 Avenue lot. Walk across the blue Smith Crossing Pedestrian Bridge, which the city rebuilt and reopened in September 2023 with signage commemorating Robert and Elizabeth Smith. Bear right, follow the loop, come back the same way. Do not detour toward the Whitemud Ravine Loop connector unless you have another hour and a topo map.
Start from the May Common access point inside the Magrath Heights neighborhood, drop into the Larch Sanctuary side first, cross the beaver dam area, and connect down into the MacTaggart section. Give yourself two hours with breaks. Bring water. There is no fountain, no washroom, and no cell signal you would want to rely on.
The single most useful thing to understand about Magrath Heights is that the ravine at your door is not maintained on your behalf. It is protected from you. That reframes the whole daily routine. It means the trail conditions are seasonal in a way city parks are not. It means bike access is limited and you should plan around it. And it means the pedestrian infrastructure the city is finishing in 2026 is doing more than easing your commute. It is stitching a walkable link between one of Edmonton's least developed nature reserves and one of its densest new commercial districts. Very few Edmonton neighborhoods will have that combination when the dust settles.
If you are thinking about how your home fits into that changing picture, or you are curious what the new pedestrian and cycling connections might mean for future demand in this corner of southwest Edmonton, The Anderson Co. is happy to talk it through over coffee.
