The pair of mirador lookouts here were closely-located. Bocastiello belvedere had puddles and was muddy. It's boulders nearby had plentiful once-seabed fossils. But the best views of these jagged limestone massifs were from Gratallera. The source of the waterfalls that feed the local rivers is a mountain cave located 1,000 m deep inside the cliff seen here.
