Missing Link offers some fun fishing for brook trout and rainbow trout. Snipe has a few trout, as well as bass and northerns. You can make a short loop out of this by using the Cross Bay entry point to begin or end your trip. Because the Missing Link Lake entry point is generally used to access the mile long Tuscaroraportage, it is often available when other permits are taken. The far eastern campsite is just enough off the main travel route to give you the solitude you are looking for.
Brant is a shallow lake with pike, perch and bass.
Spend some evenings in the southwest arm of the lake and you are sure to see some of the lake's resident moose. You are within an easy day trip of lakes with brookies and lakers in them too. And, if you head north towards Bingshick Lake, you can spend some time hiking on the Kekekabic Trail. As is the case with other routes I've mentioned, you're never far from the car in case of an emergency. Now that you've got a few places to go, don't forget the most important thing.
