Recommended Anchor Alarm Radius
60m
60m inside the river in 3–5m sand/mud. Excellent all-round shelter once inside. The APPROACH is the key risk — only attempt in calm conditions at half-flood via the S channel. River current can be strong — set anchor into the current direction and use extra scope (7:1 minimum).
About This Anchorage
Caminha is a beautifully preserved medieval fortified town at the mouth of the River Minho — the border river between Portugal and Spain. The town's 15th-century Gothic parish church, medieval walls, and waterfront squares are among the finest in northern Portugal. The anchorage inside the river provides excellent all-round shelter once the bar is safely crossed, but the entrance is DANGEROUS and must only be attempted in calm weather, at half-flood, using the S channel past the river mouth island. A cross-border ferry links Caminha to A Guarda (Spain) across the river — a fascinating short excursion to Galicia. The river can be explored upstream by shallow-draft vessels — Tui (Spain) and Valença (Portugal) are approximately 15nm upriver with anchorage options near both medieval walled towns. This is the northernmost safe anchorage in Portugal and a natural end-point for a northern Portugal cruise.

Setting Your Anchor
Scope: Use 7:1 scope minimum in Atlantic conditions — river currents and overnight swell demand extra chain. In river estuaries, set anchor into the current direction.
Swell Assessment: Check swell buoy data (Leixões, Sines, or Figueira da Foz buoys on onda.pt or windguru.cz) before anchoring at any exposed Douro North Coast location. Residual Atlantic groundswell is present even in calm E winds.
Bar Crossing Protocol: For all river and estuary entries (Douro, Rio Lima, Rio Cávado, Rio Minho): contact the relevant port authority on VHF Ch 16 before approach; enter only at half-flood with swell below 1m; never attempt on an ebb tide or with breaking seas on the bar.
Tidal Planning: Spring tidal range 3–4m. Calculate tide height against draft for marina approach at Viana do Castelo (entrance obstruction 2.5m LWS). Factor strong ebb current into anchoring — set hook into the current.
Anchoring Rules
- Anchoring fee
- Free
- Permit required
- No
Restrictions: INTERNATIONAL RIVER: Portuguese territory on the S bank, Spanish territory on the N bank and from the midline of the river. Both Portuguese GNR Maritime Police and Spanish Guardia Civil monitor the river. Standard entry reporting to Portuguese Maritime Authority applies. The channel is subject to sand movement — always use the latest chart. CRITICAL: DO NOT ATTEMPT ENTRY in swell above 0.5m on Moledo beach, or on an ebb tide.
Hazards
- !DANGEROUS BAR: The Rio Minho entrance bar is one of the most hazardous on the Portuguese coast — breaking seas have damaged and sunk vessels; ONLY attempt in genuinely calm conditions at half-flood via the S channel
- !Sand bank migration: the channel configuration changes seasonally and with storm events; always use the most current IHPT chart and take local advice
- !River current: spring tidal stream in the river can reach 2–3 knots — set anchor into the current direction and use extra scope
- !INTERNATIONAL BORDER: The midline of the Minho River is the Portuguese–Spanish border — do not cross without proper formalities completed on both sides
- !ORCA ZONE: The Minho estuary approaches are within the northern edge of the Iberian orca interaction zone — monitor orcas.pt when sailing offshore
Skipper's Tips
- →Phone the Caminha harbour authority (+351 258 921 130) or call VHF Ch 16 for current bar conditions before approaching — they know the channel state and will advise on the best time
- →Timing is everything: enter at half-flood (rising tide), swell below 0.5m, no breaking waves visible on Moledo beach; if in doubt, Viana do Castelo (12nm S) is the safe alternative
- →The upriver exploration to Tui/Valença is outstanding for shallow-draft vessels (draft <1.5m) — two ancient walled towns facing each other across the river, a unique medieval atmosphere
- →The cross-border ferry to A Guarda (Spain) runs frequently — a half-day excursion to Galicia without moving the boat; A Guarda has a spectacular hilltop Celtic settlement (Castro de Santa Trega)
Facilities
Excellent restaurants in Caminha town — traditional Minhota cuisine, fresh Atlantic fish, regional lamprey (lampreia) in season, good Vinho Verde wines. The waterfront restaurants overlook the Minho and the Spanish coast of Galicia.

Best Months & Season
May, June, July, August, September
May–September. Entry only in calm conditions at half-flood — good summer high-pressure windows in June–August provide the best opportunity. Autumn (October onward): NW swell increases dramatically; the bar becomes very dangerous and the river should only be entered in absolutely perfect conditions.
