Why Bangkok (and Why Now)
Bangkok is the gateway to Southeast Asia, but it's also a destination in its own right. The city is a blur of gold temples, neon lights, and the smell of pad thai. And it's cheap—if you know where to look. A meal from a street cart runs 40-60 baht (about $1.50). A decent guesthouse with AC costs $15-25 a night. You can do three full days, including entry fees and transport, for under $100. That leaves room for a few overpriced beers on Khao San Road, if that's your thing.
Day 1: The Grand Palace and Wat Pho
Start early to beat the heat and crowds. The Grand Palace (500 baht entry, ~$14) is the big-ticket sight. Dress appropriately—shoulders and knees covered. It's gaudy, glittering, and worth every baht. Next door is Wat Pho, home to the reclining Buddha. Entry is 200 baht (~$6). The statue is 46 meters long, and its feet are inlaid with mother-of-pearl. Don't skip the on-site massage school; a 30-minute foot massage is 260 baht (~$7).
For lunch, walk to Tha Maharaj, a small riverside mall. Grab a boat noodle soup at the food court for 60 baht. Then cross the river for free on the pier ferry (4 baht) to Wat Arun. Climb the steep prang for a view of the river. Entry is 100 baht (~$3). End the day at Soi Rambuttri, a chill street near Khao San Road, for cheap pad thai and people-watching.
Day 2: Markets, Canals, and a Rooftop Sunset
Skip the touristy Damnoen Saduak floating market (overpriced and packed). Instead, take the BTS Skytrain to Saphan Taksin, then the express boat to Tha Kha floating market (only open on weekends). It's local, less crowded, and you can snack on coconut pancakes for 20 baht.
Back in the city, explore the Chatuchak Weekend Market (if it's a Saturday or Sunday). It's massive—over 15,000 stalls. Find vintage tees, handmade soaps, and the best mango sticky rice in town (50 baht). If it's a weekday, head to the Pak Khlong Talat flower market instead—it's open 24/7 and smells incredible.
For sunset, go to the Octave Rooftop Lounge at the Marriott Sukhumvit. Drinks are pricey (300+ baht), but you can nurse one while watching the city light up. Or skip the drink and take the free elevator to the observation deck at Baiyoke Sky Tower—just buy a juice at the café.
Day 3: Ayutthaya Day Trip
Take the train from Hua Lamphong station to Ayutthaya (15 baht for third class, ~$0.50). It's a 1.5-hour ride through the countryside. Rent a bicycle (50 baht) and explore the ancient ruins—a UNESCO World Heritage site. The main temples are Wat Mahathat (famous for the Buddha head in tree roots) and Wat Phra Si Sanphet. Entry to each is 50 baht. Hire a guide for 300 baht if you want depth, or just wander—the history is palpable.
Return to Bangkok by late afternoon. For your last night, eat at the famous Thip Samai for the best pad thai in the city (150-200 baht). Line up early; it gets busy. Then walk to the nearby Giant Swing and take in the night lights.
Where to Sleep and How to Get Around
For budget digs, book a private room at Lub d Bangkok Siam or a hostel like Here Hostel. Both are clean, central, and under $20 a night. Use the BTS Skytrain and MRT subway—they're cheap (16-40 baht per ride) and avoid traffic. Avoid tuk-tuks unless you enjoy negotiating; always agree on a price before getting in (short rides 50-100 baht). For river crossings, use the public ferries (4-15 baht) instead of tourist boats.
Money-Saving Rules That Actually Work
Eat where locals eat—if a stall has a line, join it. Drink from 7-Eleven (they sell water and iced coffee for 20 baht). Skip the tourist menus; they're double the price. Use the Grab app (like Uber) for taxis—you'll pay metered rates without haggling. And always carry small bills; vendors won't break a 1,000-baht note. With these rules, your $100 budget will stretch to cover everything, plus a few splurges.
The Bottom Line
Bangkok is a sensory overload, but it's also one of the most affordable cities in Asia. For under $100, you'll see world-class temples, eat food that ruins you for home, and ride the chaotic streets. Just pack light, wear comfortable shoes, and bring an appetite. Your wallet—and your Instagram—will thank you.
