For most popular hiking spots, yes! Réunion boasts excellent network infrastructure, especially in developed areas. You'll likely enjoy strong 4G/5G signals at key viewpoints like the Piton de la Fournaise volcano and within the main villages of the 'Cirques,' such as Cilaos or Salazie. However, as with any mountainous terrain, deep valleys or very remote trails might have patchy service. It's always a good idea to download offline maps before venturing into the most secluded areas.
