Do I need travel insurance?

Yes. Do not skip this. Ensure it covers motorbike accidents, as those are the most common injuries for backpackers.

Is it safe for solo travelers?

Thailand is extremely safe for solo travelers. Use common sense, keep your passport in a locker, and avoid walking alone in deserted areas late at night.

Planning your first backpacking trip through Thailand

Plan a loop starting and ending in Bangkok to minimize travel time and costs. Stick to a north-to-south route over 21 days to balance cultural cities in the north with island hopping in the south.

Set your route. Stick to the classic 'Banana Pancake Trail' loop: Bangkok to Chiang Mai (North), then fly south to Krabi or Surat Thani for the islands. Don't try to see everything; pick three main regions to avoid spending your whole trip on buses.
Book your arrival. Book a round-trip ticket into Bangkok (BKK/DMK). It is almost always the cheapest hub. Use a flight aggregator, then buy domestic legs on AirAsia or Nok Air separately once your itinerary is set.
Arrange your finances. Notify your bank of your travel dates. Bring a debit card that refunds international ATM fees (like Charles Schwab), as Thai ATMs charge a flat 220 THB (~$6 USD) per withdrawal.
Secure your accommodation. Book your first two nights in Bangkok before you arrive. After that, use apps like Agoda (which dominates the Asian market) to book hostels 24-48 hours in advance as you move.
