Recommended Anchor Alarm Radius
50m
50m alarm radius is tight — appropriate for the narrow sound. Rock bottom means anchor can foul easily; use an anchor buoy and trip line. If holding feels doubtful, use a longer scope on chain or move to mud patch in the eastern part of the sound.
About This Anchorage
Bullerö is a nature reserve in the southern Stockholm Archipelago managed by Stockholm County as a protected landscape with old-growth forest and rich birdlife. The anchorage in Bullerösund gives access to the reserve's walking trails and the famous Bullerö naturalists' station, which has hosted Swedish naturalists and artists since the 1890s. The painter Bruno Liljefors worked here, and the station is now a museum. Anchoring is possible but rock bottom requires care. The beauty of the location and its protected status make it a special stop worth the effort of careful anchoring. Landing is permitted under Allemansrätten with nature reserve rules applying.

- →Marked trail around the main island takes 2 hours and passes through old-growth forest
- →Bring all water and provisions — nothing available on the island
- →Excellent birdwatching in the surrounding skerries — oystercatchers, eiders, and red-breasted mergansers
- →Quietest anchorage in the southern archipelago — rarely more than 3–4 boats even in peak season

Best Months & Season
June, July, August
Open all year in theory but only practical June–August. Nature reserve is most rewarding in late June–July when nesting birds are active (observe from a distance). Autumn colours in September are exceptional but anchorage is exposed.
Recommended Anchor Types
Set Your Anchor Alarm to 50m
In the Stockholm Archipelago's tight granite coves, wind shifts from overnight thunderstorms can drag anchors rapidly. Safety Anchor Alarm monitors your GPS position continuously.
