Sun Island can be visited throughout the year, but the ideal time to experience this stunning destination is during the dry season from May to September. During this period, the weather is most favourable, with clear skies, minimal rainfall, and moderate temperatures, making it perfect for hiking, sightseeing, and exploring the island’s historical sites.

The average temperatures on Sun Island during the dry season typically range from 16°C to 17°C (60°F to 63°F), providing a comfortable climate for outdoor activities without the intense heat or heavy rain often associated with the wet season. Whether you're visiting the Inca ruins, hiking the scenic trails, or relaxing by the lake, the dry season offers the best conditions for enjoying everything Sun Island has to offer.

One of the things that tourists must remember when visiting Sun Island is that there are no vehicles on the island. Therefore, visitors are limited to hiking along rocky trails (some are now paved in Inca style) or traveling by boat. Of course this all great news as long as you are up for a little bit of adventure and physical activity.

The main ports are at Pilko Kaina, the Escalera del Inca in Yumani and near the Templo del Inca and Chincana ruins at Cha’llapampa.There’s also a small port at Japapi on the southwest coast.
