Weight and bulk usually prohibit boats at highland lakes, but that’s not the case with the Klymit Litewater Dinghy, which weighs only 35 ounces and stuffs to the size of a water bottle. It inflates quickly with a clever pump-less system, can float 350 pounds, and its 210D polyester fabric is plenty durable (there’s a lifetime warranty if you do poke a hole). You’ll want to add an ultralight packable kayak-style paddle, but at this price that shouldn’t be a problem.
The Litewater Dinghy was designed for use on rivers as well and the stuff sack doubles as a pillow for overnighters.
Casting while basically lying down is a little awkward and your butt will probably get wet while getting in, but this boat is a crafty solution to finding new angles to approach high-country trout. Available at Sportsman’s Warehouse; $170.
