Currency in Sri Lanka: what to use and how to exchange

The rupee is a closed currency: you cannot buy it before you arrive, and you generally cannot take large amounts out. That makes the airport your first decision point. Arrival-hall exchange counters are convenient but rarely the best rate; a small change of Rs 5,000–10,000 covers the taxi and the first meal, then you exchange the rest in town.

ATMs are the workhorse. Bank-branded machines in Colombo, Kandy, Galle, Negombo and the bigger towns accept Visa, Mastercard and usually Cirrus/Maestro cards. Withdrawals are capped per transaction — often Rs 40,000–100,000 depending on the bank — so a large cash need means several withdrawals and several fees. Use machines attached to a bank branch during opening hours, cover the keypad, and keep the receipt.

For foreign notes, licensed exchange counters and bank branches in cities give better rates than hotels, which are the worst option. Moneychangers on the street are not worth the risk. If you bring US dollars, euros or pounds, ask for the rate before you hand anything over, count the rupees in front of the counter, and keep the slip.

Cards work for hotels, mid-range and up restaurants, supermarkets and larger shops in the cities and the south-coast tourist belt. Elsewhere — hill-country guesthouses, roadside rice-and-curry places, tuk-tuk drivers, national park touts — cash is the only option. Many small merchants that do take cards add a surcharge or quote a worse rate, so ask first.

Budget in rupees, not dollars. A mid-range day of guesthouse, food, transport and one paid attraction sits in the low tens of thousands of rupees; a backpacker day is a fraction of that. Carry a mix of denominations: Rs 5,000 notes are hard to break in a village shop, so keep Rs 100, Rs 500 and Rs 1,000 notes for small purchases and tips.

Withdraw in larger amounts less often to cut fixed fees, but not so much that you carry a week of cash through the hill country. Split money between a day bag, a money belt and your main luggage. Tell your bank you are travelling so the first withdrawal is not blocked, and check what your card charges for foreign transactions — a no-fee travel card can save real money over a two-week trip.

Prices for foreigners are often quoted in rupees with a separate higher rate at attractions; that is normal and not a scam. What is a scam is the tuk-tuk meter that is 'broken', the driver who takes you to a 'friend's' shop, and the unofficial 'guide' at a station who offers to buy your ticket. Agree the fare or use a metered app before you get in.

If you are staying a while, a local SIM and a mobile wallet can handle small payments, but do not rely on it outside the cities. Keep a paper record of what you changed and where, in case a card is later disputed.
