The park's tangles of waterways offer access to remote areas inaccessible by road or trail; here are some of the most pristine and secluded mountain scenes on the continent. Bring your own kayak and you can launch from any boat ramp or beach; otherwise, companies in several nearby towns and Seattle suburbs offer kayak and canoe rentals, portage, and tours. The upper basin of Lake Chelan (at the park's southern end) and Ross Lake (at the top edge of the park) are two well-known kayaking expanses, but there are dozens of smaller lakes and creeks between. The Stehekin River also provides many kayaking possibilities.
