What to Pack for Bangkok

• Lightweight clothing: Bangkok is 32 to 35 degrees year-round with high humidity. Cotton or moisture-wicking fabrics only.
• Modest temple clothing: Shoulders and knees must be covered for temples. Pack a lightweight long-sleeve shirt and pants.
• Comfortable walking shoes: You will walk 15,000+ steps per day. Break them in before the trip.
• Portable charger: Your phone is your map, translator, and Grab taxi app. A dead phone in Bangkok is a problem.
