Salto do Cavalo is a mountaintop N-E of Furnas with an elevation of 805 m.
But this is not your goal!
Just before the top you'll find a very fine miradouro with great panoramic views.
This is your goal!
The cache is located on a lower platform on the east side of the miradouro.
It is not a crowded place, but many a times there may be other viewers => take your time please!
