Istanbul
You just can't visit Turkey without a trip to Istanbul. The city offers a huge amount, so ideal to allocate a couple of days. The architectural beauty of The Hagia Sophia and Blue Mosque are not to be missed. Closely followed by the iconic Galata Tower and the unique underground Basilica Cistern. For photographers, the Grand Bazaar is the place to be for those colourful market seller shots, which will lead onto a walk through Sultanahmet Square. As sunset approaches, hop on a boat to cruise the Bosphorus Strait, where you'll cross between the continents of Asia and Europe, as Istanbul straddles both.
Cappadocia
Cappadocia is regarded as the number one spot in the country for spectacular landscapes and it's easy to see why. I was driving from the airport to Goreme, where I was staying, and I must've stopped 3-4 times en route, as I was in awe of the landscapes. If you're limited with time, definitely visit Goreme Open Air Museum where you've got rocky landscape combined with churches carved into the rock faces, which is fascinating to see. The other spot would be Love Valley, which was my personal fave due to the unique fairy chimney rocks, which you can also hike down to. You're essentially viewing the valley from a ridge, which operates as a large viewing platform. Final recommendation is to spend an hour in Uchisar where you have traditional houses stepped up into the landscape, along with Uchisar Castle in the background which offers great panoramic views.
Note: The hot air balloon is a huge draw, but mine was cancelled, so I can't give a review on this aspect.
Antalya
In my opinion, Antalya has a great blend of the old and the new. I stayed in the old city within walking distance of the marina. You have quaint cobblestone streets with local carpet sellers, then cafes overlooking the marina, combined with the historical site of Hadrian's Gate and Antalya Saat Kulesi. A couple of recommendations outside the city would be the Expo 2016 site which is still in relatively good condition, then further afield is Köprülü Canyon National Park, which offers spectacular beauty. There's a stone bridge overlooking the canyon where you can admire the turquoise colour water and watch the water rafting day trippers pass by.
