Colliery Dam Park

We always want to keep our information up to date. If you see any information we're missing, let us know at


This park is one of Nanaimo's larger destination parks popular especially in the summer as a fresh water swimming spot (no lifeguards on duty). It is also a dog walking destination as the trail around the upper dam is a designated dog off leash area- open during regular park hours. There are some steep trails and narrow bridge crossings along the upper dam trail.

There are two parking lots one along Nanaimo Lakes road which will lead you directly out to a bridge between the two dams. The second is at bend in the road where Wakesiah becomes Sixth Street.

Accessibility notes: Best wheelchair access is main entrance off of Sixth Street within paved parking lot. Hard-packed and level asphalt path takes visitors to the first lake. Access to upper lake requires crossing a gravel parking lot. Trails range from easy to quite steep. Washroom doors are 86 cm wide.

Colliery Dams are a rare link with Nanaimo’s industrial heritage. Built in 1910-11 by the Western Fuel Company to supply water for coal washing and for use by miners, mules and horses in the mines, the water system quickly developed an important secondary use. Homes near the pipeline were allowed to tap the line for domestic uses and eventually this water was carried to most of the homes in South Harewood.
