One of the most fascinating places on Vormsi is the Huitbergi limestone hill in a spruce forest in the middle of the island. The hill is over 400 million years old and a coral reef polished by ice. The limestone outcrop is covered with moss, but fossils can be seen in places where there is no moss. Protected ferns have found their place there.
The circular trail is marked with wooden signs.

The aim of Vormsi Nature Protection Area is to protect rare landscapes, heritage, culture and plants. The two internationally important bird protection areas on the coast of Vormsi – bays of Hullo and Sviby – and Hari strait with coastal meadows and islets are named research areas of the Royal Society for the Protection of Birds.
Interesting places: Hullo bay – a nesting and a stopping place for birds. In spring you can see thousands of scaups, long-tailed ducks, ducks, barnacle geese and woodcocks there. Rumpo peninsula is the habitat of the rare lichens characteristic for tundras, but rare in Estonia. Also take a look at Rälby bog, Dilby peninsula, Saxby beach and Prästviigi Lake.

A 6,7 km hiking trail runs from Rumpo village on Vormsi island to the tip of a peninsula bearing the same name. There are platforms along the trail affording a great view of the Hullo and Sviby bays and islets that are marked nesting and migration spots for water birds. Additionally, Rumpo peninsula is a habitat for rare lichens from tundras.
