Portugal Salto do Cabrito

A little waterfall just upstream from an old power station.

A wide angle lens will be needed to capture "enough" of the scene. Take a tripod since the place is likely to be in shade. You might also need it for long exposures

Parking available 500m from the waterfall. A 10min walk down to the waterfall is the easy part. Getting back up the steep street might take longer. You can also park further down and closer to the spot, just beware that the road is really steep and some small engined rental cars might struggle.
You can also swim under the watertfall if you like (2017), so take something for swimming. Not spectacular but still fun.
