The Haeska observation tower is one of Matsalu’s most popular bird-watching spots, with up to 128 bird species sighted 24 hours a day. For a while, it was even a record in Europe. It is worthwhile to visit Haeska to see birds as early as the end of March; the wonderful bird-watching season lasts until the beginning of November.

The Haeska observation tower provides a good view of both Matsalu Bay and the beach meadow nearby. Every spring and autumn, the shallow bay and open beach meadow with low grass attract hundreds of waterfowl and waders. In March and April, Haeska provides an excellent observation point for Northern swans. In May, huge flocks of barnacle geese and ruffs in beautiful nuptial plumage can be seen at the lookout tower. You are very likely to see a white-tailed eagle in Haeska. In autumn, many ducks and geese stop at Haeska.
