Foothills County · Sheep River Valley
Two old oil-boom towns merged into one artsy river-valley community, with Kananaskis Country starting at the end of Highway 546. Nobody ever subdivided this landscape into tidy estates — which is precisely why the people who buy here wouldn't trade it for one.
Browse by direction
With no registered estate plans to organize around, the Diamond Valley acreage market sorts itself by geography instead. Each direction out of town has its own terrain, its own drive and its own kind of buyer — so that's how we've mapped it.
West of town the pavement climbs into spruce and ridge country, ending at the Sheep River Provincial Park gate — bighorn sheep territory, quite literally. Parcels along this corridor are the valley's trophy holdings: treed, elevated and pointed straight at the Front Ranges. Owning here means Kananaskis is your before-breakfast option, not your long-weekend plan.
Upper end of the valley's range
The river carved a series of benches through the valley, and the acreages perched on them get the double payoff: water sounds below, mountain silhouettes above. These are the parcels that make visiting friends go quiet on the deck. Slopes, setbacks and the odd escarpment mean walking the land before you love the photos is mandatory homework.
Bench premium over open ground
North and east the trees thin out and the land opens into rolling pasture, which is where the market's larger parcels live — the 15-to-28-acre holdings for buyers whose plans involve horses, hay or a healthy fear of neighbours. Millarville's farmers' market and racetrack sit up the road, and Calgary's commute shortens with every kilometre in this direction.
More acres per dollar out here
Twenty minutes south, Longview guards the stretch of Highway 22 that Hollywood keeps borrowing — the Cowboy Trail scenery behind more westerns than the hamlet has residents. This is working ranch land, so true residential acreages are scarce enough that we fold Longview into this page rather than pretend it has its own market. When one lists, it goes fast and it goes famous.

The Diamond Valley file
On January 1, 2023, Black Diamond and Turner Valley — twin towns that spent a century glaring affectionately at each other across the Sheep River — amalgamated into the Town of Diamond Valley. The merger changed the letterhead more than the character: this remains a community built on Alberta's first oil boom (Turner Valley's 1914 Dingman well started it all) that reinvented itself as one of the province's most likeable small-town main streets. Expect to hear locals use all three names for another decade. They've earned the right.
Here is the honest heart of this market: there are no named estate subdivisions around Diamond Valley. Rural property trades as unplatted acreage — individual titles of roughly 2 to 28 acres, mostly $800,000 to $1.5 million — shaped by creeks and section lines rather than a developer's cul-de-sac template. That means no architectural committee approving your fence stain, no HOA fees, and no two properties that resemble each other. It also means every purchase is bespoke: zoning, access, water source and outbuilding rights vary title by title, so due diligence does the work a subdivision plan would normally do for you.
The town itself is the amenity. Diamond Valley runs on galleries, live music, a stubbornly good coffee culture, the landmark Marv's Classic Soda Shop on the Black Diamond side and Eau Claire Distillery on the Turner Valley side — farm-to-glass spirits in a town of under three thousand people. Acreage owners here get a social life most rural markets can't offer: fifteen minutes from the quietest road in the county, someone is always playing a set somewhere.
Highway 546 runs west from town and simply becomes Kananaskis Country — Sheep River Falls, the bighorn wintering range, trailheads that Canmore visitors would queue for. No park gates jammed with tour buses, no two-hour approach drive. For hikers, fly-fishers and anyone whose truck permanently smells like a wet dog, this is the cheapest mountain access of any acreage market in southern Alberta, and it quietly underwrites every property value in the valley.
Without subdivision names to search, Diamond Valley rewards a different technique: set MLS alerts by radius rather than community, expect listings tagged variously to Diamond Valley, Black Diamond, Turner Valley, Millarville and Longview, and be ready to move when the right parcel surfaces — inventory at any given moment might be a handful of properties. Every title needs its own file: confirm the zoning district, the road access agreement, the well record and what the county will let you build before you fall for the view. Which you will. Everyone does.
Good questions
Why are there no named estate subdivisions around Diamond Valley?
Because the land was never carved into planned enclaves — and honestly, that is the sales pitch. Rural listings around Diamond Valley trade as unplatted acreages, typically 2 to 28 acres, generally between $800,000 and $1.5 million. Instead of matching gate posts and architectural controls, you get fence lines that follow the terrain, a mix of eras and building styles, and neighbours measured in fields rather than metres. Buyers who want a curated estate community should look toward Okotoks or De Winton; buyers who want actual country end up here.
What happened to Black Diamond and Turner Valley?
They amalgamated. On January 1, 2023, the neighbouring towns of Black Diamond and Turner Valley — separated by little more than the Sheep River and a friendly rivalry — officially became the Town of Diamond Valley. Addresses, signage and habits are still catching up, so you will hear all three names used interchangeably, and MLS listings may reference any of them. Same valley, same community, one town hall.
Can I buy an acreage in Longview?
Occasionally, but do not hold your breath. Longview, twenty minutes south on Highway 22, is working ranch country — the parcels that trade there are usually quarter-sections and grazing land rather than residential acreages, which is why we cover it on this page instead of giving it a page of its own. When a genuine country-residential property does surface near Longview, it tends to come with staggering Highwood River valley views and a lineup of buyers who have been waiting years for exactly that call.
