The easiest wave to access the standing surf wave at the Bend Whitewater Park is west of the river at Mckay Park, 166 SW Shevlin Hixon Dr, Bend, OR 97702. Mckay Park is currently under construction but you can park on the street and walk along the north side of the construction fencing towards the wave. From there wade across a shallow section of the safe water passage channel then proceed upriver to the second wave from the top, that’s the surf wave. Do not try and access the wave from the east side of the river as that area is the protected habitat channel.
