I’ve got no commerical interest in this tour but having just come back from Estonia I can recommend the country and this company. Contact them direct for more information though the tour seems mainly focussed on birds there will presumably be a chance to see a mammal or two
We still have places for a 5-day Autumn tour Wed29Sep – Sun03Oct. The Special price is 500 Euro pp.
