A Bit of History

The dams at this park are a rare link to Nanaimo’s industrial and coal mining heritage, and as of 2002, recognized and registered as one of Canada’s Historic Places.

The Harewood Colliery Dam was built in 1910-11 by the Western Fuel Company as a place to wash coal. It was also used by the miners, mules and horses in the mines, and as a water line to nearby homes. The water system was eventually carried to most of the homes throughout South Harewood until another dam was built in 1932.

The lakes created by the dams are now a popular swimming and fishing location.

The Trails at Colliery Dam

The outer trails of the park form a figure 8 around the two small lakes, with a few interconnecting pathways. The area also connects to the Parkway Trail, a 20 km paved path connecting several of Nanaimo’s beautiful parks.

Within Colliery Dam, the trails are varied in topography as well as difficulty. You will find paved sections, a few bridges, walkways with stairs, bridges built specifically for mountain biking, as well as mulched wooded trails. These wooded trails have a few beautiful large trees scattered throughout.

Colliery Dam Park is a great destination for families. The 2.3 km loop around the park is easy to navigate and well maintained. And if you like waterfalls, two can be found here!

Finding the Waterfalls

The first waterfall is actually a spillway from the dam, but still quite pretty to view.

Heads towards the first bridge as you follow the paved path to your left when leaving the parking area off Wakesiah Avenue. The spillway you see under this bridge is the first waterfall. Take the dirt path down the hill on the left hand side of the bridge and follow the spillway to the bottom. This path is quite steep and out of park boundaries.

Chase River Falls, or better known as Granny Falls, is the more significant waterfall found at this park. However, it’s a bit more hidden.

To find Granny Falls, you first need to find the large culvert that allows Chase River to flow underneath the Parkway. It’s so large, in fact, there is a wide concrete walkway inside the culvert. And if you enjoy graffiti art, this tunnel is full of it (both good and not so good)!

You’ll find the culvert by heading to the highest point in the park and also where the wooden pedestrian bridge and walkway is found near the upper lake. On the parks map, this upper lake is called “Middle Colliery Dam”. After crossing the wooden walkway, locate the culvert ahead of you. Walk through the culvert and continue to follow the dirt trail for a short distance to Granny Falls. If these directions don’t work, find Chase River within the park and follow it upstream.

Dog Park

The dog park is located at the upper lake, AKA “Middle Colliery Dam”. The trail that loops around this portion of the dam is an off-leash area. Many families enjoy walking their dogs in this section.

The parking area closest to the dog park is off of Nanaimo Lakes Road. This parking area also leads you directly out to a bridge between the two dams.

Wheelchair Accessibility

The best wheelchair access is from the parks main entrance off of Wakesiah and Sixth Street. This paved parking lot gives you access to a hard-packed and level asphalt path that leads you to the first lake.

Negatives about this Park

I’d be remiss if I didn’t mention a few of the negative aspects of this park.

  • Although the city is trying to update this “University District”, Harewood is a well-known high crime area (petty crime). Please don’t leave anything of value in your vehicle when you park.
  • The park is surrounded by busy roads, including the Parkway (Hwy 19). This means that vehicle traffic noise is quite evident throughout most of the park.
  • In saying both of these points, I still believe it’s a worthwhile location to explore.

  1. We’ve been visiting these falls through “the painted tunnel”, as it’s fondly known in our family, for years. I especially appreciated the short loops when the kids were very small — sometimes on a longer hike you hesitate to let the curious young children stop for lengthy periods to explore freely because in the back of your head you’re thinking “shoot we still have such a long way back to the car…” but these loops are perfect for the youngest meandering walkers to stop at every bit of interesting thing. You’re never so far that you can’t just pick them up and head back even if there’s a meltdown at the furthest point 🙂
