Can I Travel the World Solo with $25k? Realistic?

Hey everyone! So, I recently inherited some money, and I’ve been saving up while working because I’m planning to quit my job and embark on a long-term solo travel adventure in 2026. I’m from New York, so I know I can snag some great flight deals. When I travel, I always stick to one bag – a carry-on with a maximum weight of 12 kg. But I’m wondering, is this feasible for extended solo travel?

I’ve set aside $25k for this trip, and while I don’t necessarily intend to spend it all, I want to make sure my plan is realistic. As a US citizen who only speaks English, I’ve got my international phone plan and trusty iPhone in tow. Safety is my top priority as a solo female traveler, which is why I prefer staying in hotels over hostel dorms these days.

Having visited cities like Auckland, Seoul, Tokyo, and Paris, among others, I have some international travel experience under my belt. However, this will be my first extended solo journey. My rough itinerary includes starting in Europe, then moving on to Southeast Asia before finishing up in Latin America. I’m a bit concerned about visa runs, especially in Southeast Asia, and I’m seeking advice from seasoned travelers on budgeting, safety, and overall wisdom for a trip of this scale.

I’m debating between planning for a 6-month or 10-month adventure to give myself a financial cushion. Am I crazy for attempting this? Any tips on places to visit, essential items to pack (remember, I’m only taking one bag), and general advice on long-term travel would be greatly appreciated.

And just to clarify, while I appreciate financial advice, I’m covered in that department as I work in finance and studied math in university. My main worry is my physical safety since I don’t know how to drive. So, if you’ve embarked on a similar journey or have insights to share, please chime in. Thanks in advance for your help!
