Lagoa Azul is one of many clear warm lakes along the cearensese coastland.
This one is near (1 hr) Jeri.

It has some "restaurants" along the shore.

Pedra furada.......... must be said, probably the most overrated ridiculous "tourist attraction" on earth.
I thought they were joking but some local guides and jeri-enthusiasts sincerely consider this rock to be a
one of a kind, super fantastic world class site the like of which does not exist anywhere else in the world.
Heartbreaking to tell them that they really should get out more and that there are literally thousands
far more impressive rock arches around the globe and that almost every country has them.

It's a nice diversion in any case in this otherwise attraction starved environment,
something to do....

It's a half hour trail along the coast to the east.
