While Pertosa can be visited year-round, the best time to go is during the spring (April to June) and fall (September to October).During these months, the weather is pleasantly mild, making it ideal for exploring the Pertosa-Auletta Caves, the main attraction. Temperatures are comfortable for walking and outdoor activities, and you'll experience fewer crowds than in the peak summer months. This period is particularly suitable for couples and families looking for a relaxed trip without the intense summer heat.Summer (July and August) is also an option, especially if you plan to combine your visit with other destinations in Campania. However, temperatures can be quite warm, and the caves might be busier.
