Can I Take My Dog to Thetis Lake?

Yes, you can take your dog to Thetis Lake, and October is the best month of the year to do it. Dogs are welcome on the park's forest trails, there is a designated off-leash dog beach where they can swim, and the summer beach restrictions lift after September 15. The one thing to check before you go is blue-green algae.

Ziggy's favourite swim of the year happens here every fall. Once the summer crowds clear out, Thetis turns back into a local lake, and the off-leash dog beach on Upper Thetis gets the shoreline mostly to itself.

Where can my dog swim at Thetis Lake?

West Beach, on the north side of Upper Thetis Lake, is the park's designated off-leash dog beach. You reach it off the Upper Thetis Lake Trail, and it is the one spot in the park where dogs can run and swim free. It is open year round.

From June 1 to September 15 the main Thetis beach and the Prior Lake beach and dock area ban dogs entirely, except to pass through on a leash without stopping. Once that window closes, dogs can use them under the normal leash rules, which is exactly why fall is the season.

What are the leash rules on the trails?

Outside the off-leash zone, dogs must stay on a leash and under control, and everyone must stay on the designated trails. The park protects sensitive Garry oak and wetland habitat, so the off-trail shortcuts you see in summer are the thing getting people fined. CRD fines for off-leash outside a designated area run $100 to $300.

What are the trails like for a dog walk?

The trail network circles Lower and Upper Thetis through second-growth forest, roughly a 6 km loop around the two lakes if you link the shore paths. It is gentle, mostly shaded, and dry enough under the canopy even in a wet fall.

The Galloping Goose and the E&N Rail Trail are both minutes from the park, so you can pair a leashed distance walk with an off-leash swim in a single outing. That combination is hard to beat anywhere in the region.

Is the water safe for dogs right now?

Blue-green algae is the real risk at Thetis. The CRD posted an advisory at the Lower Thetis main beach this summer, and blooms can appear into the fall. The toxins can kill a dog, so check the CRD blue-green algae alert page before you let your dog in the water, and do not let them drink lake water anywhere in the park.

Our guide to blue-green algae explains why the blooms are so dangerous and what the warning signs look like in a dog.

What is it like to live near Thetis Lake?

The park straddles View Royal and Langford, and the housing on each side is different. On the View Royal side you get compact homes and townhomes with the trailheads a short drive away. On the Langford side you get bigger yards, newer builds, and the same lake access.

For buyers with dogs, we treat proximity to Thetis as a real feature. A year-round off-leash swim spot within ten minutes changes how you live with a dog, and it is one of the first questions we ask when a family says they want to be near the water. Our View Royal guide and Langford guide cover both sides of the park.
