Ilves, who is flying in from Latvia, is being hosted by President Tarja Halonen. They are to hold a joint press conference on Monday afternoon. Ilves will then meet with Prime Minister Matti Vanhanen.
Halonen will hold a dinner in his honour at her official residence, Mäntyniemi.
The 52-year-old Social Democrat MEP was elected to the post after winning a vote in the Presidential electoral college. He narrowly defeated the incumbent Arnold Rüütel.
Ilves is a former Estonian Foreign Minister and Ambassador to the United States. He was born in Sweden and educated in the US.
Ilves took office last week. The post of President in Estonia is largely ceremonial. Ilves is the fourth man to hold the job, following Konstantin Päts (1938-40), Lennart Meri (1992-2001) and Rüütel (2001-06).
