Canoeing on the River Gruda is scheduled for Saturday, Kubilius says.
"We have a great opportunity to have informal communication during such informal meetings, discuss current affairs, but no decisions are made during them. Cooperation of the three Baltic states on very important strategic projects is very intense, and of course, we'll talk about that too," Kubilius said.
"But we'll also talk about the upcoming canoe trip on the River Gruda. We faced that challenge in Estonia several years ago," Kubilius told journalists on Friday.
Lithuanian Prime Minister Andrius Kubilius, Latvian Prime Minister Valdis Dombrovskis and Estonian Prime Minister Andrus Ansip and their spouses will stay in Druskininkai until Sunday.
The heads of government will be introduced to the resort, visit a local snow arena and monastery, will be informed about investments made in Druskininkai.
The prime ministers are also scheduled to discuss economic issues and joint energy projects, Jarda Paukštienė, spokeswoman for the Lithuanian prime minister, told BNS.
Such informal meetings are traditionally held in one of the three Baltic states.
