Personally I would say your better off fishing Spencer. Its mostly stunted walleye but should keep your lines busy. An excellent place to unload is right before Siebert lake. There is a small staging area with a quad ramp. If you decide to go to Pinehurst instead you can easily go there from that same staging area.
Note of caution... If you head into Spencer take the legal access along the range line on the north west corner of Seibert. Word is wardens have a few trail cameras on the shorter illegal creek access on the north east corner of Seibert and people have been getting tickets in the mail.
Here is a link to the park map. There are several other better versions out there.
