We are snowbirding on Vancouver Island and spend a month in Victoria before moving up island to Nanaimo.
Victoria has 2 full service RV parks open all winter. Fort Victoria RV Park is located beside the main highway through the city. It has the usual services but it is noisy. C$42 per night for a short stay is expensive. Check their web site for longer term stays. When we were investigating snowbird sites, we found them to be too expensive so decided to stay at the WestBay Marine & RV Park located on the inner harbour across from the Empress Hotel.
Much smaller RV park with a great location right on the ocean but it is still basically a parking lot with hookups. There are great walking paths and it is only a few minutes drive to downtown. No road noise but you do hear seaplanes and helicopters regularly. We would stay there again.
In Nanaimo, we have been in the Living Forest RV Park mentioned by another Greg here on this thread. This is a friendly, family owned and run private campground that looks like a Provincial Park. Lots of trees, site separation, paved interior roads, walking trails, clean bathrooms, showers, laundry and lounge. It is at least as nice as their web site shows. Rates are excellent. We will be back for another winter's stay.
FWIW, we took the toad up Island to check out other campgrounds and none come close to Living Forest. It all depends on what you are looking for, of course.
We have been on Vancouver Island since December 28 and have seen only 4 or 5 overnight low temperatures that hit the freezing mark. No snow (woo hoo!) but at least some rain on about half the days. Sure beats the stuffing out of an central Alberta winter!
