Cubs / Scouts Sandboarding at Lake Wainamu June 10, 2018August 19, 2018admin 1114 views Our Scouts invited the Cubs for a walk around Lake Wainamu, near Bethels Beach. It was very muddy! Our Scouts BBQed some sausages for lunch, then we had a fun time sandboarding down the Giant Dunes. Everyone got filthy, but had a great time.
