Do I need to carry cash?

Yes. While cities use cards more, rural areas and markets are cash-only. Use a fee-free debit card (like Schwab or Revolut) to withdraw local currency at ATMs.

Is it safe for solo travelers?

Yes. Southeast Asia is generally very safe. Use common sense, keep your passport in a locker, and never leave your drink unattended.

Solo Backpacking Through Southeast Asia: A Step-by-Step Planning Guide

Plan a 3-month loop starting in Bangkok, focusing on a loose itinerary that allows for flexibility. Budget for $40–$50 per day to cover hostels, street food, and local transit while using regional budget airlines for long-distance jumps.

Map your route. Stick to the 'Banana Pancake Trail' (Thailand, Laos, Vietnam, Cambodia) for your first trip. It is well-trodden, safe, and makes meeting other solo travelers easy.
Secure the right visas. Research entry requirements for each country 30 days before departure. Use official government e-visa portals rather than third-party agencies to save $20–$50 in service fees per visa.
Book the first three nights only. Book your arrival hostel in Bangkok or Hanoi. Don't book the rest of your trip in advance; you will meet people in hostels who will suggest better routes and group trips.
Pack for laundry cycles. Carry enough clothes for 7 days. Laundry services are available on nearly every street corner in Southeast Asia for roughly $1–$2 per kilo.
