Foreign Currency Regulations
Visitors to Sri Lanka bringing in more than US$10,000 should declare the amount to the Customs on arrival. All unspent rupees converted from foreign currencies can be re-converted to the original currency on departure as long as encashment receipts can be produced.

Sri Lanka's Currency
The local currency is the Sri Lankan Rupee, divided into 100 cents (you rarely come across cents today). Currency notes are Rs.5,000, Rs 2,000, Rs 1,000, Rs 500, Rs 100, Rs 50, Rs 20 and Rs10. Beware of mistaking the Rs 500 note for the somewhat similar Rs 100 note. To check whether notes are genuine when not given at a bank, look for the lion watermark. Coins, should you receive them, will be in denominations up to Rs 10.

Time Difference
Sri Lanka Standard Time is five and a half hours ahead of GMT. (Allowance should be made for summer-time changes in Europe)

Electricity
230 - 240 volts, 50 cycles AC. If you travel with a laptop computer bring a stabilizer.

Local Health Care
Minor health problems can always be treated by doctors with practices in the resorts and elsewhere in the country. If you have a more serious problem, Colombo now boasts a selection of modern, well-equipped private hospitals offering the latest in conventional medical and surgical therapies. A growing number of foreigners are taking advantage of affordable, high quality private healthcare in Sri Lanka, and combining it with the chance to take a holiday.
