The detour to this (small, but nice) waterfall can be reached in about 4 minutes. If you add some time for taking pictures, you will be back at the suspension bridge in just over 10 minutes of pure walking time. For my taste, a worthwhile detour 👍

Here is this tree that has been badly damaged by humans and must be preserved. This can only be achieved if we (humans) leave it alone and stop damaging it with our vanities.
