I've visited 38 countries. Here are 3 cities I always recommend to other travelers.

As someone who grew up in Singapore with a Thai mother and Irish father, travel has always been a big part of my life.

From visiting relatives around the world to exploring new places as a family, my favorite memories always involve touching down in a new city.

I've been lucky enough to visit 38 countries so far, and when people ask for my travel recommendations, these three cities always top my list.

There's so much to love about Dubrovnik, Croatia

Dubrovnik, Croatia, has everything I look for in a European summer destination: fascinating history, traditional restaurants and bars, and rocky beaches in secluded coves.

Surrounded by the sparkling blue Adriatic Sea, Dubrovnik feels majestic yet quaint: visitors can easily get their bearings around the city in a day or two.

I recommend exploring the historic Fort Lovrijenac, a centuries-old fortress that was also used as a filming location for "Game of Thrones."

A lap of the city walls is also a must for the most incredible panoramic views of the sea.

Bergen, Norway, is perfect for outdoor adventures

Located in Southwestern Norway, Bergen is a charming city with museums and colorful wooden houses on the old wharf. I really enjoyed stopping by the Fish Market near the waterfront for fresh sushi.

Make sure you also dedicate a day to taking the funicular, or cable train, up Mount Fløyen for challenging hiking with stunning views.

The real treat of visiting, though, is the opportunity to take a day trip into the fjords and beyond. I traveled to Flåm, Norway, where I boarded a boat to Nærøyfjord, one of the narrowest fjords in the world.

There's something for everyone in Singapore

I may be biased since I grew up in this Asian city-state, but I consider Singapore a must-visit destination for all travelers.

Growing up here, I didn't appreciate how much it had to offer, but now, I make the most of every trip home to see my parents.

For example, I love exploring the open-air food courts called hawker centers and checking out the new local bars and cafés. I also enjoy exploring the stunning Singapore Botanic Gardens, which is a UNESCO World Heritage site.

If you're looking to work up a sweat, I recommend climbing Fort Canning Hill. Once at the top, stop to explore a historic World War II bunker called the Battlebox.

Whether you're a history buff or a foodie, there's truly something for everyone in Singapore.
