Cultus Lake is about an hour from Burnaby. I have never been, but Robert said it is nice.
It is clear water and with a nice dock for people to walk on and jump off, it is nice. Parking sucks at $7 an hour I think it was. We got early so we could choose a good spot because these places do get crowded.
One thing that did suck about this place was there wasn’t any showers.
