What Travellers Say
Reviews Summary
Visitors are impressed by the unique, almost spiritual atmosphere of the São Domingos Pomarão Trail, highlighting the striking toxic lagoon and fascinating abandoned mine ruins. It's described as an oasis and an apocalyptic yet beautiful scene, perfect for peaceful exploration outside peak season. However, the beach bar's ambiance and musical selection received criticism, and the lagoon's toxicity means swimming is not an option.
"Impressive place. It's a must to visit"

"Childhood memories and an oasis in an unexpected arid place. Invites us to slow down from the fast pace of life and stay still, feeling and sensing everything that surround us: the crickets in summer warm nights, the beautiful night sky filled with stars, the refreshing water of the lagoon, walking and feeling the scent of eucalyptus. A truly peaceful experience, almost spiritual.
The only setback is that in July and August the lagoon is far too crowded ad well as the beach bar ( which needed a different style both in decoration and musical selection)"

"The strangest archaeological site I have ever visited. An abandoned copper extraction mine with an apocalyptic scenario of ghostly buildings and a large toxic lagoon where the acidic waters display shades of red and yellow."
