Its varied nature makes Antnäs-Börstskär an island well worth visiting. The types of nature on the island include large-growth forest, pine moor and rock formations. Antnäs-Börstskär has one of the best night harbours in the archipelago. You are almost always sheltered from most winds, except northwesterly winds.
If you take a short evening stroll up to the heights on Sörskäret, you get a good view to the west, towards Kunoön Island and the mainland. The western inlet is the most visited area on the island. Practically the whole bay has a sand bottom and is well-suited for bathing. The best moorings are by the flat rocks on the north side of the bay. The depth here is good right up to the shore, and there is a floating jetty with room for ten boats (guest marina), sauna, tourist cottage, toilet and two grill sites.
