Oregon's second largest lake, Waldo Lake is one of the wildest and prettiest of Oregon's mountain lakes to tour by canoe. Hundreds of thousands of migrating birds fill the skies above the marshy shores of Oregon's largest lake. Mt. McLaughlin’s snowy cone stands like a pyramid to the west. Herons build huge nests high in the cottonwoods of gravely islands where the swift waters of the McKenzie and Willamette Rivers braid together.
