Garner Lake - closst accomodation is at the Beresford Lake Campground - from there is a relativily short paddle to Garner.

Wallace Lake - another provincial campground - then east to Siderock Lake and then into WCPP through Crystal.

As for a combo of wallyes and lake trout - not on the west side I'm afraid.  You would have to journey to Carroll LAke, down the picturesque Haggart R., for walleye (no trout here) or east of Haggart Lake to Glenn, Mexican Hat or Rostoul or Hansen for walleye (some of these have trout too).

Don't tell anyone but if you are coming in from Crystal, I would paddle (dragging a surface line if you are coming in the spring) through Broken Arrow, Haggart, Triangle, Welkin, Bulging, Aegean. If you have any arms left from catching and releasing all those trout, then head over to Mexican Hat for a quick walleye shorelunch before heading back.
