Sea kayaks offer much of the feel of recumbent bikes and trikes:
--You sit low with your feet out in front of you, and watch the ground or water go by while you are close enough to touch it.
--The non-motorized experience can be very quiet, so you can be attuned to the natural sounds of your surroundings; it can also be adrenaline inducing (e.g. rapid descent, high waves.)
--It is more like wearing your vehicle than sitting on it or in it. Or to use another simile, it is like an extension of your body.
The bike bridge at right, part of the Spruce Railroad Trail, spans a cove on Lake Crescent on the Olympic Peninsula.
Sea kayak heading under the Spruce Railroad Bike Trail bridge
The Spruce Railroad Trail follows the trackbed of a railroad constructed to haul out spruce for building airplanes in World War I. The war ended before the tracks were ever used. Now the bike trail follows uses the old grade along the roadless west side of Lake Crescent.
This bike bridge, a short detour from the railroad bed, spans a deep cove of emerald water. The trail then follows close to the winding water's edge and then returns to the railroad grade. The old tunnel through the rock cliff is currently being refurbished for cycling.
The lake and trail provide a great opportunity to explore this section of Olympic National Park in easy recline, whether in a kayak or recumbent.
(I took these pictures before getting my trike.)
