If you decide to launch at the end of the Temagami Lake access road be sure to take at least 2 gallons of water with you to leave in the car. This is for when you come back to your vehicle, that will be parked about 2 miles down the road from the launch, to get the dust off your windshield so you can see to drive. If you park in a residents #'d parking spot or the reserves private lot on the North side you will be ticketed, towed or worse by the owner of the stall you took.
This may also be the last year for non residents/tax payers to use the ramps for free, or park for free. Most bring everything with them and don't even know the way into town so add no economic value to the Municipality and the majority have had enough. The Municipality and Band Council are currently working together to form a corporation to control the end of the road.
The better approach IMHO is to come into town, forget the 45 minutes of beating your stuff up on the road to the hub. Launch your boat for free beside Temagami Outfitters (turn left at the gas station, then 2 buildings over). Tie your boat to the far end of the dock, go park your truck/trailer over the tracks behind the train station, walk back and hit the LCBO and grocery store on the way back to your boat via Wildflower Drive that will take you right back to the ramp.
