Exploring Bangkok doesn’t have to follow the tourist circuit. Sometimes, the city unfolds best when you let your feet and the train lines guide you. Here’s how my day went—told through the places, the food, and the little discoveries that made it memorable.

Starting at Siam Square

My day began at Siam Square. Nothing fancy, just the usual kickstart before heading out to explore.

Backpacker Tip: Coffee shops near BTS hubs open early and make good spots to plan your route.

A Sweet Pink Milk

On my way to Chulalongkorn, I spotted a vendor with a rolling cart selling the Thai classic—pink milk (nom yen). Sweet, milky, and neon bright, it’s the kind of street drink that feels like Bangkok in a cup.

Backpacker Tip: Street carts are worth trying. Drinks and snacks often cost less than 30 THB, and you’ll discover flavors you won’t find inside the malls.

Wandering Through Chulalongkorn University

From Siam, it’s a short walk into Chulalongkorn University. The grounds felt like a calm island within the city—shady trees, wide paths, and buildings with character.

• Faculty of Architecture

• Faculty of Fine and Applied Arts

• The Fountain Plaza – with the Thai and Chulalongkorn flags and the King’s portrait rising in the background.

Backpacker Tip: University campuses in Bangkok are underrated. They’re free to enter, quiet compared to tourist zones, and often ringed by affordable food stalls.

A Practical Stop: 7-Eleven for a SIM Card

On the way toward Chinatown, I ducked into a 7-Eleven to buy a local SIM card. The staff asked for my passport, registered it, and within minutes I had 10 GB of data ready to go. Quick, cheap, and far more convenient than relying on hostel Wi-Fi.

Backpacker Tip: Always buy your SIM at 7-Eleven. It’s straightforward, official, and usually activated on the spot.

Law Faculty & Tuk-Tuks

The Faculty of Law had a more serious air, but what caught my attention was the line of tuk-tuks parked out on the side, waiting for passengers. I grabbed a selfie with them—an instant Bangkok postcard.

Exploring Chinatown

A long walk led me into Chinatown, where the pace shifted again—lanterns overhead, sizzling food stalls, and the hum of trading.

I stopped for a bowl of noodles in a glossy broth, topped with stalks of greens. I never learned its name, but it was hearty and strange in the best way.

Backpacker Tip: In Chinatown, it’s best to just point and order. Most stalls don’t have English menus, but the food rarely disappoints.

The rest of the area was alive with street food, jewelry shops, and souvenir stalls. Perfect for slow browsing before moving on.

Terminal 21 by Train

From Chinatown, I hopped on the MRT Blue Line (Hua Lamphong Station) and connected to the BTS to reach Terminal 21 Mall (Asok Station).
• Fare: about 30–40 THB.
• Travel Time: 20–25 minutes.

📍 The mall is styled like an airport terminal, with each floor designed after a different city. It’s playful and air-conditioned—a sharp contrast to the street chaos of Chinatown.

A Cashless Coffee Shop Surprise

Later, I wandered into a coffee shop, tucked under a major TV station building. This one was different: no cash accepted—cards only. My international card worked fine, but it’s worth noting if you’re used to carrying only cash.

Backpacker Tip: Always keep a card handy in Bangkok. Street food is strictly cash, but some cafés and offices are cashless.

Key Takeaways for Backpackers
• Use the BTS and MRT instead of taxis—faster and cheaper.
• Street drinks like pink milk are cheap, refreshing, and part of the local flavor.
• University campuses are hidden gems for quiet walks.
• 7-Eleven makes SIM card activation easy—bring your passport.
• Chinatown is best explored slowly; eat first, shop after.
• Terminal 21 is a fun mix of shopping and theme-park vibes.
• Be prepared for both cash-only and card-only situations.
