Upset as I was, it took a long time to fall asleep, and I nearly had a heart attack when the hotel’s automatic wake-up call made the landline ring at 4:20 – half an hour before my alarm clock was set. We left around 5:40, and it was cold at that time, though it would get really hot during the day. Around sunrise, we reached our first destination – a caravanserai (kervansaray in Turkish, کاروانسرای, kārvānsarāy], in original Persian). Between the 2nd century BCE and the 15th century CE, Europe and China were communicated through the Silk Road, a network of trade routes frequented by caravans. Caravanserai were roadside inns built alongside those trade routes. They were fortified inns which protected the traders from bandits and weather, providing food and water. In Turkish, they are also called han.

Öresin Han (also called Tepesi Delik Han, “the han with a hole on the roof”) is a restored caravanserai / han. It was built in 1188, according to a plate that was recovered during restoration. The works lasted between 2007 and 2010, saving the building from literal ruins (and the aforementioned hole on the roof). Nowadays, it is a shop and inn for tourists. It has thick walls and a vaulted interior to withstand the weather and possible attacks.

We continued on the road for hours until an early lunch at noon, then drove to the World Heritage Site Hierapolis-Pamukkale, a combination of historical site and geothermal activity. First and foremost, there is the travertine formation. Travertine is a sedimentary rock made out of calcium carbonate which precipitates from fresh water – basically, the material stalactites are made of. Sometimes, in thermal areas, they deposit in cascade form with lakes and waterfalls.

The Pamukkale travertine formation Pamukkale travertenlerinde is a terrace formation around 2,700 metres long, 600 metres wide and 160 metres high. The local thermal water oozes onto the surface at a temperature between 35 and 100 ºC and saturated with calcium carbonate. At the surface, carbon dioxide degasses and the calcium carbonate precipitates into a gel that will crystallise into travertine. Unfortunately, the waterfalls have been mostly drained now to feed pools at the hotels.

Even from the Classical era, the travertines have attracted visitors to the point that a thermal spa was founded around the 2nd century BCE, which eventually became the town of Hierapolis. In the year 133 BCE, Hierapolis was incorporated into the Roman Empire.

We had some time to wander around the place, but way too short to actually see even a quarter of what was on display, which was frustrating – but this would again happen at every archaeological site. Along one of the nice ladies from my group, I saw the Roman baths, then basilica, now museum, which contains the smaller items unearthed – sculptures, friezes, sarcophagi. We then climbed up to the Temple of Apollo Apolion and the Temple of Pluto Ploutonion – which are closed off as the cave underneath them emits asphyxiant carbon dioxide due to the geothermal processes.

There is also a swimming pool on site, and after hiking up to the theatre it might have even been inviting, if not for the fact that you could actually step onto an area of the travertines to experience them first-hand. I of course took the chance, and was surprised at how… non smelly it was, used to sulphur thermal waters in Japan.

I did not understand why we had to leave so early, because then we just ended up at another hotel with nothing around – thinking back, I have reached the conclusion that the guide was overworked, and he kept a schedule of going to sleep early and getting up early too, that is why we were at all the hotels at 18:00 at the latest; not an excuse, but an explanation. We were at Colossae Thermal & Spa Hotel around that time. The hotel did not have a lift, and most of our rooms were on the first floor. The hotel staff brought the luggage up, and we were reassured it would be taken down again the following morning. I… had a feeling it would not.

In accordance to the thermal and spring water reputation of the region, the hotel had a thermal centre. It comprised a swimming pool, a warm pool and a jacuzzi inside. Outside, there was an actual thermal water / mud pool – which was great for relaxing, but at 33 ºC, I could not stay for long (and I tried not to feel guilty as I knew the water is deviated from the travertines). By this time in the trip, too, I had inserted myself into a group of nice people, and made acquaintances with a nice couple, which was good because it’s always useful to have someone telling you that you’re about to get into the shower with your glasses on…
