Erickson Lake from Island Lake

I'm considering a trip to Erickson Lake this weekend. I have never been there, but I am considering going from the Crystal Lake trailhead to Island Lake, and from there connecting with a pack trail that branches off of the Smith Morehouse trail west of Island Lake. I saw this pack trail on an online map, but know nothing about it. I will be going with my 13 year old son, with the intent to fish at Erickson, and any place interesting along the way. Does anyone have any recommendations for a route to Erickson? Is this route something that will work for us? any info/advice welcome.


Thanks.
