Prästviigi lake is a closing up coastal lake and its springs worthy of visiting are located in its north edge. The lake is an important fish spawn for the fish of the coastal waters and a good source of food for the birds. Also, one can see various species of orchids there.
Good to know: The length of the trail is about 10 kilometres and the time needed for passing it on foot is 5–6 hours and by bike is 3–4 hours. The trail is mostly covered with gravel, hence it is more suitable for cyclists. You can also camp in Hullo and there is a viewing platform near the springs.
