Reservations are required for Madeira’s Classified Hiking Trails managed by IFCN (Instituto das Florestas e Conservação da Natureza). This includes popular routes such as PR1 Pico do Areeiro – Pico Ruivo, PR8 Ponta de São Lourenço, PR9 Caldeirão Verde, PR10 Levada do Furado and PR11 Vereda dos Balcões. Not every walking trail on the island requires a reservation, so always check the official trail status before setting out.
