Thailand

Thailand's banana pancake trail supports over 35 million annual visitors with $5 massages and overnight train beds for $10—30% cheaper than similar services in #6 Scotland. Its 1,000+ backpacker hostels average $8 per night with included breakfast, faster than the typical rival in Southeast Asia. The country's safety record, with 0.3 violent incidents per 1,000 tourists, rivals Japan's benchmark for solo female travelers. No other destination matches Thailand's combination of affordability and developed solo infrastructure.
