Recommended Anchor Alarm Radius
50m
50m in sheltered Biesbosch creek anchorages in 1–3m. Excellent mud/clay holding — anchors set immediately in soft freshwater mud. Tidal range only 0.5–1m — minimal scope adjustment needed. Quiet, sheltered, and beautiful.
Setting Your Anchor
- Check tidal height for tidal locations (Hoek van Holland, Scheveningen, Biesbosch); Grevelingenmeer and Veerse Meer are non-tidal
- Plan arrival at HW for tidal locations; non-tidal lakes can be entered at any time
- In Rotterdam waterways: monitor VHF CH 67 and stay in designated small craft areas at all times
- Set your anchor alarm immediately after anchoring — before going below or sleeping
About This Anchorage
The Biesbosch is one of the largest freshwater tidal areas in Western Europe — a 9,000-hectare labyrinth of waterways, reed beds, willow forests, and tidal creeks in the former Rhine-Meuse delta. Created by the St. Elisabeth's flood of 1421 (which drowned 33 villages), the Biesbosch was farmland converted to wetland overnight. Today it is a National Park and one of the finest wildlife areas in the Netherlands: beavers (reintroduced 1988, now >150), ospreys, white-tailed eagles, kingfishers, otters, and an extraordinary variety of migratory birds. The freshwater tidal system (the only one in Western Europe) creates a gentle tidal range of 0.5–1m. The network of creeks (killen) is navigable by shallow-draft vessels up to 1.5m. Many areas are motor-free zones — sails and paddles only. The Biesbosch Visitor Centre at Drimmelen is the gateway to the park.

Anchoring Rules
- Anchoring fee
- Free in designated anchorage zones; mooring pontoons available in some areas (€8–14/night)
- Permit required
- No
Restrictions: NATIONAL PARK: no-motor zones strictly enforced (6 km/h speed limit, or motor-free entirely, depending on creek); no disturbing wildlife; no anchoring in reed-bed areas or wildlife sanctuaries; overnight anchoring permitted in designated areas only — check Staatsbosbeheer current access map; some areas closed for nesting April–July.
Hazards
- !No-motor zones: strictly enforced by Staatsbosbeheer rangers — fines apply for speeding or using motors in prohibited zones
- !Shallow creek network: many creeks have 1m or less at LW — draft over 1.2m limits access significantly
- !Navigation without updated charts/GPS is dangerous in the creek labyrinth — the system is complex; use dedicated Biesbosch chart supplement
- !Tidal HW access: some creeks only accessible around HW — time entry for flood and plan LW position carefully
- !Wildlife disturbance: beavers, nesting birds, and otter are easily disturbed; maintain distances and keep noise to minimum
Skipper's Tips
- →Hire a Canadian canoe at the Drimmelen visitor centre and explore the creeks at eye level — beavers are regularly visible at dawn and dusk
- →The overnight anchorage deep in the creek network is one of the most peaceful experiences in the Netherlands — silence, kingfishers, and the sound of tide
- →Download the Staatsbosbeheer Biesbosch app before entering — it shows current no-motor zones, wildlife closures, and designated anchoring areas
- →Dawn in the Biesbosch during spring migration (April–May) is exceptional — bring binoculars and a bird guide
- →Dordrecht (gateway to the Biesbosch) is one of the oldest cities in the Netherlands — worth a full day visit before entering the park
