Tourism brings both benefits and drawbacks to Mira de Aire, Portugal. It provides income for the local economy but also increases pollution, traffic, and noise. The town is home to the largest caves in Portugal, the Mira de Aire Caves, which were discovered in 1948 and opened for tourism in 1974, with 800 meters accessible to visitors. Other attractions include the Aquagruta water park open from June to September, the 15th century church now converted to a museum, and the 4 km long Mira de Aire forest.
