To explore Rhodes in one day, it’s best to rent a car or hire a taxi to get around quickly and efficiently. There are plenty of rental agencies and taxis available in Rhodes Town, and prices are reasonable. Expect to pay around €50-80 for a full-day car rental or €80-100 for a taxi tour of the island. Keep in mind that parking can be difficult in some areas, so plan accordingly.
If you have more time, consider visiting the Old Town of Rhodes, another UNESCO World Heritage site with beautiful architecture and winding streets. If you have less time, consider skipping the Filerimos Monastery and spending more time in Lindos. Also, be sure to wear comfortable shoes and bring sunscreen and water, as the island can get quite hot in the summer.
