Paddle estimates follow mapped lake shapes around shores and islands, excluding portages. Missing lake paths remain labeled straight-line. Mapped trail distances follow trail bends; unmapped hiking connections are unknown, not lake crossings. Paddle or hiking mileage, conditions, closures, and campsite availability must be confirmed before departure.
1. Check feasibility
Review each carry and the total carry burden, especially if you plan to double carry.
2. Choose camps
Reserve named sites on lakes along the route; a route does not guarantee campsite availability.
3. Confirm conditions
Wind, ice, closures, landing conditions, and daylight can override a mathematically short route.
