The Johnston Canyon is right by a gas station had that great prices!
The trail is a narrow but fancy boardwalk. There are 2 waterfalls and when you
get to the second one you will see the moss (?) that is growing on some of
the rock.
The hike is an easy hike; 1.1 km to the lower falls and then a total of 2.7km to the upper falls
where you turn around and go back.
