Arcomagno Beach is generally safe for swimming when seas are calm, though space is limited in this small cove beneath the natural arch. The beach becomes very crowded during peak summer, which can make swimming less comfortable and finding a spot on the sand challenging. Access involves steps and can be slippery, requiring caution, especially with children. Water depth increases quickly, so supervise young swimmers closely. The confined space means that on busy days, the beach reaches capacity quickly. Visiting early morning or late afternoon, or during shoulder seasons, provides safer, more pleasant conditions with ample personal space.

For photography, visit Arcomagno Beach early morning or late afternoon when lighting enhances the natural arch and turquoise water while avoiding harsh midday sun. Late May, June, and September offer the best combination of good weather and manageable crowds, crucial for this small, famous cove. July and August see the beach packed with visitors, making it difficult to capture the iconic view without crowds. Weekdays are always preferable to weekends. The morning light particularly illuminates the arch beautifully, and arriving early ensures you'll secure a spot in this tiny, highly sought-after beach before tour groups arrive from surrounding towns.
