We were picked up near the hotel at 5:10 AM, and after a break, we had time to enjoy Hierapolis-Pamukkale from around 10:30 AM to 2:00 PM. Those who want to do activities might find this time short, but for us, about two and a half hours was sufficient. Lunch starts around 2:30 PM, which is quite late (though it's a very delicious buffet), so we recommend bringing some snacks. There is one bus transfer each way, but the journey was comfortable, and we were very glad to have been able to visit Pamukkale at this time.
