Nelson has good MTB. Check with the local bike shop. Camp at Kokanee creek PP, drop off the trailer, drive up to Kokanee glacier PP for good hiking.
Another option from what SideHill has suggested is to drive to New Denver from Nelson, camp at the municipal CG and drive to the hiking areas in the Valhalla PP. Do a search for hiking trails on the BCParks website.
Drive to the Arrow Lakes(too bad you don,t have your canoe) and cross at Fauquier. Continue onto Vernon where there are a number of PP CG locally.
MTB Kalamalka Lake PP and Ellison PP. Good flowy biking. This area can get busy and hot during the summer but there are plenty of lakes to cool off.
Drive to Kelowna. Get a trail map for Smith Creek trails for MTB in the West Kelowna area. Lots of trails.
Lots of camping in the area but can be busy in summer.
Drive to Penticton and get directions to 3 Blind Mice MTB area.
After you are totally thrashed from riding, hopefully not too much blood is spilt, drive to Princeton and then to the EC Manning PP for some great hiking. There are camping areas around at various PP. From Here, Vancouver is only a 3 hour drive.
Have a nice summer.
Dave.
