Thunderhook Fly-ins & Smooth Rock Camp is located north of Armstrong and in the heart of the best Brook Trout fishing in Ontario. They offer multiple fly-in outpost camps to choose from on remote lakes and a fly-in lodge. They offer lakes and streams with great Brook Trout fishing. Brook Trout actively migrate to find food and cooler water as the heat of the summer moves in so you will have to contact Thunderhook for details on where to find Brookies during the summer. In the spring and fall Brook Trout are easier to find. Guests purposely targeting Brook Trout should be able to get 3 to 6 nice Brook Trout on an average day. The trout are most common in the 1 to 2 pound range but 3 and 4-pounders do get caught. They also have outstanding fishing for Walleye, Lake Trout and Northern Pike.
