Turkey's Best Attractions
The essentials: Hagia Sophia in Istanbul (around €25 for the foreign-visitor upper galleries; it's an active mosque, so it closes during the five daily prayer times); the Blue Mosque (free, same prayer-time closures apply); Topkapi Palace (the Ottoman sultans' seat of power, with an extra-fee Harem wing); and Pamukkale's white travertine terraces near Denizli (around €30, includes the Hierapolis ruins, best combined with a Cappadocia or Aegean-coast leg of the trip since it's a detour from Istanbul).
Turkey's biggest attractions come with rules that catch first-timers off guard — prayer-time closures, euro-denominated entry fees, and mosque dress codes among them. None of it is complicated once it's spelled out, so here's the honest version: what things actually cost in 2026, when to show up, and what to skip.
Hagia Sophia, Istanbul
Once a Byzantine cathedral, then an Ottoman mosque, then a museum for nearly a century, Hagia Sophia was reconverted to a working mosque in 2020. The ground floor is reserved for worship; foreign tourists visit via a separate upper-gallery route, with an entry fee of around €25 (children under 8 free). It closes to visitors for roughly 90 minutes around each of the five daily prayer times, with the longest closure around Friday midday prayer — check the schedule before you plan your day around it.
The Blue Mosque (Sultan Ahmed Mosque), Istanbul
Directly across the square from Hagia Sophia and free to enter, the Blue Mosque is named for the thousands of handmade blue İznik tiles lining its interior. Same prayer-time closures apply as Hagia Sophia. Modest dress is required: shoulders and knees covered, and a headscarf for women — loaner scarves and wraps are available free at the entrance.
Topkapi Palace, Istanbul
The primary residence of Ottoman sultans for roughly 400 years, with courtyards, the Imperial Treasury (home to the Topkapi Dagger and an 86-carat diamond), and a separate-ticket Harem section that's genuinely worth the add-on rather than a tourist upsell. Book a timed-entry ticket online in peak season (May–September) to skip a long queue.
Pamukkale's travertine terraces
Pamukkale ('cotton castle' in Turkish) is a set of gleaming white mineral terraces formed by calcium-rich hot springs, near Denizli in southwestern Turkey. Entry (around €30) includes the adjacent Hierapolis Roman ruins and a small archaeology museum; a dip in Cleopatra's Antique Pool costs extra. Shoes come off to walk the terraces themselves. From Istanbul, it's most efficiently reached by a short domestic flight to Denizli followed by a roughly one-hour drive, or as part of an organized multi-day tour combined with Ephesus.
What to skip
- Unlicensed 'guides' who approach near the Blue Mosque or Grand Bazaar offering an impromptu tour for cash — stick with a licensed operator booked in advance.
- Carpet-shop 'free tea and a look, no obligation' invitations near the major sights — they're a well-known soft-sell funnel, not a genuine cultural exchange.
- Skipping the Harem at Topkapi Palace to save the extra fee — it's consistently rated as one of the most interesting parts of the whole palace.
