If you are driving an hour out of Edmonton expecting a sprawling, resort-style tourist destination, you need to recalibrate your itinerary right now. Castle Island is almost entirely made up of private property, making it less of a traditional day-trip spot and more of a fascinating roadside curiosity. It holds the official title of Canada's smallest summer village, and knowing exactly what to expect saves you from an awkward turnaround at the end of a very narrow causeway.
- Population: 15 permanent residents (2021 Census)
- Total area: 0.05 km² (about 12 acres)
- Location: Eastern tip of Lac Ste. Anne, Alberta
- Public access: Extremely limited (mostly private cottages and driveways)
- Distance from Edmonton: ~75 km (about a 1-hour drive)
The Story Behind the Name
The name sounds like something out of a European fairytale, but the reality is deeply rooted in 1890s Alberta history. French-born Indian Agent Charles de Caze bought this tiny speck of land on Lac Ste. Anne in 1896. His purchase price was a mere three dollars an acre. He envisioned a massive four-story stone chateau with battlements and three-foot-thick walls, intended as a lavish summer retreat.
He originally named the spot Constance Island in honor of his daughter. Unfortunately, de Caze passed away at 44 before the grand project could be finished. The abandoned two-story stone shell sat on the island for decades. Locals naturally started calling the striking ruins "Castle Island," and the name stuck permanently.
Fast forward to the Prohibition era. A local known only as "Mr. Shorty" purchased the island, tore down the crumbling stone walls, and brought in small cabins. He hosted lively parties and eventually built the very causeway you drive on today.
By 1955, the land was officially subdivided and incorporated, transforming into the tight-knit summer village it is now. Today the community is still self-governed, with its own summer village council overseeing the 18 cottages that line the shoreline.
Can You Actually Visit Castle Island?
The short answer is no, not in the way you might visit a provincial park or a public beach. Castle Island is a designated municipality, but its tiny footprint consists entirely of private cottages and narrow residential lanes. Census records count only 9 of the island's 18 dwellings as occupied year-round, which explains why the streets feel empty outside of peak summer weekends. There are no public beaches, picnic tables, or commercial facilities on the island itself.
Driving across the short causeway is possible, but you will quickly find yourself at a dead-end surrounded by private driveways. Parking is virtually non-existent for non-residents. The best way to appreciate Canada's smallest summer village is from the water. A slow cruise past the island by boat gives you a great view of the shoreline properties without encroaching on the residents' privacy.
Things to Do Around Lac Ste. Anne
Since the island itself won't take up your afternoon, the surrounding Lac Ste. Anne area easily fills the rest of your itinerary. This eutrophic lake spans over 50 square kilometers and serves as a massive playground for water sports and summer recreation.
Fishing and Water Access
Lac Ste. Anne is highly active with boaters, windsurfers, and anglers. You can launch your watercraft from several public boat launches on the mainland. Fishing here targets northern pike, yellow perch, and burbot.
Walleye populations have faced heavy pressure over the years, so you need a special harvest license to keep them. Always check current Alberta fishing regulations before casting your line, as local conservation efforts are strict.
Nearby Alberta Beach
Just a short drive along the lake's eastern shore brings you to Alberta Beach. This is where you find the public amenities Castle Island lacks. The sandy shoreline is perfect for a family afternoon.
You also have access to the Beach Wave Park, local farmers' markets from May to October, and plenty of spots to grab a quick lunch. It makes the perfect anchor point for your Lac Ste. Anne day trip.
How to Get to Castle Island
Reaching the causeway is a straightforward drive from Edmonton. Head west on Highway 16, then take Highway 43 north towards Lac Ste. Anne County. You will eventually connect to the Lac Ste. Anne Trail (Highway 633), which wraps around the eastern edge of the lake.
The trip takes about an hour in good traffic. Keep an eye out for local fire ban signs as you enter the summer village zones, as the municipalities here enforce strict fire protocols to protect the heavily wooded shorelines. If you are hauling a boat, map out your launch point at Alberta Beach or West Cove beforehand, rather than pulling your trailer down the narrow Castle Island causeway.
