Turkey.

1,500 years old, a cathedral then a mosque then a museum then a mosque again — and still one of the most awe-inspiring interiors on the planet. Now an active mosque, so entry is free for the main floor but there's a ticketed gallery/upper section for tourists. Dress modestly, shoes off, avoid prayer times.

Tip: Go at opening or late afternoon to dodge the tour-bus crush. Pair with the Basilica Cistern (5 min walk) and the Blue Mosque (across the square) for a single monument morning.

The six-minaret Ottoman masterpiece facing Hagia Sophia across the park. 20,000 hand-painted İznik tiles give it the blue glow. Free to enter as a working mosque — closed to tourists during the five daily prayers, so time it between.

Tip: Covered shoulders/knees, women cover hair (scarves lent at the door). The exterior at blue-hour from Sultanahmet Park is the shot.

The Grand Bazaar is 4,000 shops under one roof since 1461 — carpets, lamps, gold, ceramics, leather. The Spice Bazaar down the hill is smaller, more local, better for Turkish delight, saffron, tea. Both are a sport: haggling expected, prices start at 3× for tourists.

Tip: Buy nothing on the first pass. Halve every opening price and be ready to walk — they'll call you back. For real value, the shops in the streets AROUND the bazaar beat the ones inside.

The Turkish bath is a must-do once: marble sweat-room, a scrub that removes a layer of you you didn't know was there, a foam massage. The historic tourist ones (Çemberlitaş 1584, Kılıç Ali Paşa, Hürrem Sultan) are beautiful but pricey; neighbourhood hammams are a fraction of the cost.

Tip: The historic tourist baths — Çemberlitaş (1584, the most central), Kılıç Ali Paşa, Cağaloğlu, and the upmarket Ayasofya Hürrem Sultan — charge a premium for the scrub-and-foam works, with the luxury ones climbing well into three figures; prices move with the lira, so check the current rate. For a fraction of that, local neighbourhood baths (like Ağa Hamamı near Taksim, Gedikpaşa near the Grand Bazaar, or Çinili in Üsküdar on the Asian side) do the same job. Agree the exact package and price before you undress, decline the mid-scrub upsells, and tip the attendant 10–20% in lira cash.

The best food day in Istanbul isn't in the old city — it's a ferry ride away in Kadıköy. The market streets around Güneşlibahçe: fish sandwiches, midye dolma (stuffed mussels), Çiya Sofrası for regional Anatolian home cooking, then meyhanes and craft-beer bars after dark.

Tip: Çiya Sofrası is the one food writers fly in for — order the mezze spread and whatever's in the day's pots. Take the ferry from Eminönü at sunset for the skyline on the way over.

Every tout on the waterfront sells a 'Bosphorus cruise'. Ignore them. The public city ferries — Eminönü↔Kadıköy, or the longer Şehir Hatları Bosphorus line up to Anadolu Kavağı — give you the same palaces, fortresses and mansions from the water for a couple of dollars on your Istanbulkart, tea and simit included.

Tip: Sit on the top deck, buy a çay from the onboard steward, throw a bit of simit to the gulls following the boat. Best cheap hour in the city.

Touts inside arrivals steer you to an unmarked car, quote a flat fare 3–4× the meter, then 'have no change' for your note. Only use the official taxi rank, BiTaksi/Uber (dispatches licensed yellow cabs), the HAVAIST bus, or the M11 metro. Insist on the meter ('taksimetre').

Tip: IST airport is far from the centre — a legit metered fare is real money, so know the rough price before you land and never hand over a big note expecting change.

The theatrical Turkish ice-cream vendors near the tourist sites turn handing you a cone into a two-minute yank-it-away comedy bit. Harmless fun — until you're charged three or four times the normal price for the privilege, or a 'small' becomes a stacked A$10 cone. It's a photo op, not a bargain.

Tip: Fine to enjoy once — just agree the price and size FIRST, and know that maraş dondurma from a normal shop is a fraction of the tourist-strip price.

A shoe-shiner drops his brush ahead of you; you pick it up, he insists on a 'thank-you' shine and then demands a fortune. Or a warm, perfect-English local befriends you, walks you to his cousin's carpet shop / a bar, and you get a bill for hundreds. Both run on Aussie politeness.

Tip: You don't owe strangers your afternoon. Politely decline the shine, and never let a new 'friend' pick the bar — the rakı-bar bill shakedown (padded bill, menu-less, muscle at the door) is the expensive version of this one.
