India

India's rail network is one of the largest and busiest in the world -- book ahead through the official IRCTC system for popular routes, and consider a higher class for overnight journeys.

Domestic flights are increasingly affordable -- IndiGo, Air India, and several budget carriers connect every major city.

Within cities, app-based rideshares (Ola, Uber) are widely available, while auto-rickshaws remain a cheap, iconic way to get around short distances.

India is generally safe for travelers who take sensible precautions, though it's an enormous, varied country and risk factors differ significantly by region and by traveler.

• Scams targeting tourists are common in heavily touristed areas -- overcharging, fake "government approved" shops steering commissions to touts, and unlicensed taxi/rickshaw drivers quoting inflated fares. Use registered prepaid taxi counters at airports/stations, agree on a fare or insist on the meter beforehand, and be skeptical of unsolicited "helpful" strangers near major sights.

• Solo women travelers should take extra precautions -- avoid traveling alone late at night, dress conservatively, and prefer registered transport over hailing anything on the street; India's own tourism boards and most guidebooks specifically address this given real, documented incidents.
• 
  
• Food and water safety is a genuine everyday consideration -- stick to bottled or purified water, be selective about street food (busy stalls with high turnover are generally safer than empty ones), and expect some adjustment period for a system unused to local food and water.
• 
  
• Traffic is a significant hazard in itself -- India has one of the world's highest road fatality rates, and crossing streets or renting a vehicle requires a level of defensive awareness well beyond what many visitors are used to.
• 
  
• Border and conflict-sensitive regions, including parts of Jammu and Kashmir and the northeastern states, may have travel restrictions, permit requirements, or elevated risk -- check current government advisories before planning travel to these areas specifically.

• Emergency number: 112 works nationwide and connects to police, fire, or medical services.
