π‘οΈ Safety
Colombo
Colombo is generally safe for travelers, with violent crime against tourists being uncommon. Petty theft, tuk-tuk scams, and overly persistent touts are the main annoyances. The city has made major safety improvements since the end of the civil war in 2009.
Lhasa
Violent crime against foreign tourists in Lhasa is extremely rare β the city is heavily policed and tour operators are responsible for their clients. The primary risks are altitude sickness (which can be life-threatening), intense UV at 3,656 m, and the unusual constraints of travelling in a politically sensitive region where photography of security personnel, any political statement, or any mention of the Dalai Lama in public can cause serious problems for your Tibetan guide and operator, even if not directly for you.
β Ratings
π€οΈ Weather
Colombo
Colombo has a tropical monsoon climate with high humidity year-round. Two monsoon seasons bring rain at different times, but the city rarely experiences an entirely dry month. Temperatures stay consistently warm throughout the year.
Lhasa
Lhasa is classified as a high-altitude semi-arid plateau climate β thin, dry air year-round with over 3,000 hours of sunshine annually (one of the sunniest cities in China). Daytime is warm in summer and cold but sunny in winter; nights are always cold because of the altitude. The monsoon brushes the plateau in July and August, bringing short afternoon showers but rarely all-day rain, making Tibet considerably drier than the Himalayan regions to the south. Wind and UV are intense year-round at this elevation.
π Getting Around
Colombo
Colombo's traffic is notoriously congested. Tuk-tuks are the quintessential way to get around, but ride-hailing apps provide more predictable pricing. The city bus network is extensive but chaotic. A new light rail system is under development.
Walkability: Walking in Colombo is possible but challenging due to broken sidewalks, heavy traffic, and intense heat. The Fort and Galle Face areas are the most walkable. Carry an umbrella for sudden rain and use sunscreen year-round.
Lhasa
Lhasa is small and manageable β the old town around the Jokhang and Barkhor is entirely walkable, and most tour itineraries use a private vehicle with your assigned driver and guide for the outlying monasteries (Sera, Drepung, Norbulingka, Potala). Independent public transport is possible within Lhasa city itself for short distances, but no foreign tourist should be taking long-distance buses or taxis alone β your Tibet Travel Permit requires you to be with your guide for essentially all sightseeing.
Walkability: The old Tibetan quarter around the Jokhang is wonderfully walkable β narrow whitewashed lanes, prayer-wheel corridors, and a flat grid you can cover in a morning. The Potala, Norbulingka, Sera, and Drepung are all too far to walk and sit at awkward angles from the centre; your tour vehicle or a taxi is required. Altitude makes walking feel slower than it looks on a map for the first 48 hours.
The Verdict
Choose Colombo if...
you want Sri Lanka's gateway β Galle Face sunsets, Pettah bazaars, curry-and-hoppers, and trains south to Galle + Ella tea country
Choose Lhasa if...
you want Tibetan Buddhism's holiest city at 3,656m β Potala Palace, Jokhang Temple, Barkhor kora, and the world's highest railway β requires Tibet Travel Permit
