Road signs also indicate to slow down so as not to run over amphibians. It's funny.

This must-see was a little sad during my visit. The pond does not seem to be maintained and the vegetation is taking over the footbridge as well as the small pontoon which was not passable. Too bad because this place can be very nice!

This very pretty pond has a wooden bridge which allows you to observe the fauna and flora without disturbance. Road signs also indicate to slow down so as not to run over amphibians. It's funny.
