Pedra Lume is an old salt mine located inside the crater of an extinct volcano on Sal Island, Cape Verde. Visitors can float effortlessly in the highly saline waters, which are said to have therapeutic benefits. The site is generally accessible, though the path down into the crater can be uneven; assistance may be needed for those with mobility issues. Both solo and guided visits are common, with guided tours offering insights into the area's history and geology. Year-round access is typically available due to the consistent climate. The cost to enter and float in the Salinas is approximately €5-10. A typical visit lasts 1-2 hours, allowing ample time for floating and exploring the unique landscape.
