Neither fully Europe nor entirely Asia,

but a city perched right on the border of both.

From the moment I chose Istanbul as my travel destination,

my heart started fluttering with excitement.

It was absolutely wonderful when I went with a friend,

but in 2027, I'm heading back to Istanbul

with my parents!

I'm seriously so excited...!

Using my past experience as a guide,

I've been researching where to take them.

Today, I want to share the absolute must-visit spots:

My curated list of the BEST 4 Things to Do in Istanbul.

If you're currently planning your own Istanbul itinerary,

use today's post to plan the perfect, action-packed trip!

1. Hagia Sophia

When planning an itinerary for Istanbul,

there is one place that simply must be at the very top of your list.

It is, of course, the iconic "Hagia Sophia".

It served as a cathedral during the Byzantine Empire,

a mosque during the Ottoman Empire,

and later a museum for a long time.

Today, it is operating as an active mosque once again.

Seeing centuries of Christian and Islamic heritage

layered together under a single, breathtaking dome

truly makes you feel like you are looking at

the entire city of Istanbul captured in miniature.

The only downside is that while visitors used to be allowed on the ground floor,

tourists are now restricted to viewing the interior from the second-floor gallery.

Turkey is an incredibly mystical and beautiful place,

especially with how seamlessly East meets West.

Since the exterior looks like a cathedral, yet the interior

is deeply infused with rich Islamic culture,

this is an absolute non-negotiable stop on your trip.

Just keep the strict dress code in mind!

Women must cover their heads with a scarf,

and both men and women should avoid clothing

that exposes shoulders or knees.

Be warned: the visitor lines here are unimaginably long.

Plus, if you try to buy tickets on-site,

they often try to upsell you on museum combo passes that you might not need.

I highly recommend booking your tickets online in advance! :)

2. Basilica Cistern

Located right next to Hagia Sophia,

making it incredibly easy to visit both together,

is the "Basilica Cistern" (Yerebatan Sarnıcı).

Though it translates directly to "Subterranean Palace,"

it is actually a colossal underground reservoir

built during the Byzantine era.

The scale of this place is so massive that you can't help but go, "Wow..."

It feels absolutely mystical and grand.

The most famous attraction inside

is the stone-carved Medusa head placed upside down at the base of a pillar.

It's tucked away deep inside the cistern,

so make sure you don't miss it!

If you see a crowd gathered with cameras,

that's exactly where Medusa is.

Some sections of the floor can be wet and damp,

so wearing non-slip shoes is highly recommended.

I wore sandals once and almost slipped and fell...

Here's a pro-tip...!

Instead of buying separate tickets for

Hagia Sophia and the Basilica Cistern,

booking them as a combo is a much better deal.

You can skip the long ticket lines and save money,

so if you're planning to visit both in one day,

I highly recommend booking a combo ticket

in advance.

3. Topkapi Palace

This is Topkapi Palace, the actual residence of

the Ottoman Empire's sultans.

If the Hagia Sophia and the Basilica Cistern represent

religious and historical symbols, Topkapi Palace was

the absolute heart of power

back in the day.

The grounds are massive, with gardens, the Harem,

the treasury, and mini-museums

scattered all over. To properly explore it,

you'll need to budget at least

three solid hours.

My absolute best recommendation for visiting

is to book a guided tour! :)

The Harem section usually requires a separate ticket,

but wandering through the quarters where the sultan's wives and concubines lived

really paints a vivid picture of palace life back then.

Personally, I highly recommend adding the Harem tour to your visit!

Before coming to Istanbul,

I was obsessed with a manga series

all about the imperial harem.

Actually visiting Topkapi Palace made me realize,

"Ah, so that's why there was so much political scheming!"

It made the whole experience so much more intriguing and fun.

Plus, the breathtaking, panoramic view of the Bosphorus Strait from Topkapi

is reason enough to put this place on your bucket list. :)

4. Dolmabahce Palace

Built right along the shoreline of the Bosphorus,

Dolmabahce Palace is often called the "Palace on the Sea."

Said to be modeled after the Palace of Versailles,

it has a much more European flair than Topkapi Palace.

Its crowning jewel is without a doubt

the world's largest collection of Bohemian crystal chandeliers.

Many tourists line up immediately at the first gate inside to take photos,

but if you walk just a bit further, there are identical gates all along the side.

So don't waste your precious time waiting right at the entrance! :)

Unfortunately, photography is strictly prohibited inside,

but it is the absolute definition of pure, unadulterated luxury...

The interior is mind-blowingly gorgeous.

Legend has it that when James Cameron, the director of *Titanic*, saw Dolmabahce,

he desperately wanted to shoot the movie right here.

However, the palace officials turned him down, so they had to build

a replica set of the Grand Staircase from scratch.

Wow... if you've seen the opulent interiors in *Titanic*,

just imagine this place being even grander and more dazzling!

Since the weather was a bit gloomy when I visited,

I've bookmarked this as a "must-revisit on a sunny day" spot.

I highly recommend you don't miss out on this stunning masterpiece!

Most of Istanbul's iconic attractions require paid entry, and the lines can be incredibly long.

If you try to buy tickets on-site at every single spot,

you might end up spending more time waiting in line than actually sightseeing.

That's why my friend and I found a better way:

booking guided tours!
