You could ride down to Wawawai
Canyon on an almost entirely flat course by riding to Red
Wolf, crossing the bridge and taking a left past the Port
of Wilma . Wawawai is 30 miles from Southway. There
are restrooms and water in the park but you have to climb
up to get into the park and up again to get out of the park.
Instead you might choose to
turn around at Steptoe Canyon about 12.5 miles down.
You’ll know it because the road crosses a bridge and
splits going up the canyon. Or go a couple of more miles
to Nisqually John’s Landing. There is a public
restroom at the landing but no running water. That should
be a 30 mile round trip. The traffic should be light west
of Red Wolf. I don’t recommend riding East from
Red Wolf on the Whitman county side during the week. Too
much truck traffic.
