Hartland can be really fun. There is some great tech stuff. If you have a couple of hours here is your loop:
up regional trail north, down trillium for a warm up -> up sidewinder to Northridge -> Jelly roll and then up breathless (yes it will make you this and not because of the view) -> huge ribbon (baller trail!) -> left on southridge and down hot cherry (double blacks were OK on a fully rigid hardtail) -> fire drill to little face and down small craft warning to inventive to mother hucker and out.
If you don't have as much time climb switchback for bragging rights and go across dave's line (another classic) then take some of the double blacks back to the car.
There is another area in Victoria called partridge hills which is fun but I see that the trails were taken down off of trailforks which makes it hard to navigate this rat's nest. I think Oak bay bikes has a weekly group ride here - you could try calling them.
Finally, take a day and go to duncan and do maple syrup on maple mountain. Best 2 hours you will spend on your bike in a long time.
