Cascata da Ribeira do Ferreiro, also known as Poço da Alagoinha, is a stunning natural paradise located on the island of Flores in the Azores, Portugal. It features a series of waterfalls cascading into a lagoon surrounded by lush, vibrant greenery. Accessibility can be challenging, requiring a moderately difficult hike; sturdy footwear is recommended. While solo visits are possible for experienced hikers, a guided tour can enhance the experience and ensure safety. The best time to visit is during the warmer months (late spring to early autumn) when the weather is more favorable and the trails are less slippery. The cost is generally low, primarily involving transportation to the trailhead. A typical visit lasts approximately 2-4 hours, allowing ample time for hiking and enjoying the scenery. Be prepared for potentially muddy conditions and bring rain gear, as the Azores can experience sudden weather changes.
