The UK is followed by Germany (39,718), France (38,780) and Spain (23,068) in current 2022 visitor numbers, according to new data from the Costa Rica Tourism Board (ICT).
The organisation said the country has seen a "massive increase" of UK arrivals since 2021 and is now close to reaching pre-pandemic arrival figures (41,810 UK visitors in 2019).
Rob Wilson, UK representative of ICT, said: "We are delighted that Brits are returning to Costa Rica and to see how the UK has moved from last year’s travel restrictions to becoming Costa Rica’s largest source market in Europe at the moment.
"This is especially important bearing in mind that direct flights from the UK to San Jose, the country’s capital city, don’t run all year round at present."
