Is Cambodia safe for solo travellers?
Cambodia can work well for solo travellers on the main tourist route, but the useful margin is practical: secure transfers, late-night decisions, bag and phone care, backup payment and connectivity, and current official advice for any border or security changes.
Answer
Solo Cambodia is easier when the ordinary logistics are settled before they become tired decisions: know how you are leaving the airport or bus station, avoid unnecessary late-night transfers, keep phones and bags secure, and carry backup cash and connectivity. Siem Reap is often the softer solo base; Phnom Penh asks for more city sense; islands add ferry and isolation considerations. Border and security conditions are a separate current-facts question, not routine travel friction, so check official advice before building a route around them.
