bigfin:

You've picked a really nice area to introduce your dad to. We stayed on Emerald 3 years ago in September at a site on a point on the southeast side of the lake, immediately south of where the portage from That Man Lake comes in from the north (site IP5 on the database). It is a nice, flat, grassy site with a view of Emerald towards the east (looking at the ridge to the south from the campsite one can still see the effect of the great blowdown of 1999 at the very top of the ridge but it doesn't detract from the site).

Emerald is nice, secluded, quiet and a pretty lake to explore.

Have a great trip!
