Yes, I have camped at the site you are referring to and it is an excellent site, with firewood at the back of it.  Mind you, this was back around 2002.  And yes you can access the ski trails from this site with a little bit of bush whacking.  There is a stream at the back of the site that flows into Pinetree.  If you follow this stream up to where it forks (about 10 minute walk), take the right fork and it will take you to Leaf Lake.  From here there is a nice trail that will take you right up to Bud Lake and around it to Highway 60.

​I managed to get to the ski trail from this site pretty easily (although an uphill climb).  Also, at back of your site, there is another trail to your left that takes you to a lookout that is pretty amazing.  From this spot you can see all of Pinetree Lake as well as other parts of Algonquin Park.  It is a pretty steep uphill climb though, again about a 10 minute climb.
