Zumaia Anchorage Guide

The Anchorage

Anchor in 2–5m on mud and sand inside the Ría de Zumaia, S of the road bridge. The ría formed by the Urola river provides excellent shelter from virtually all directions once inside the entrance. The entrance passes the dramatic Flysch cliffs (UNESCO geopark) — timing the entrance for mid-tide or above avoids the shallowest sections of the bar (minimum 1.5m at LWS). Call Zumaia harbour master VHF Ch 09. Tidal range 4–4.5m. The ría is relatively narrow — anchoring space is limited; ferry and fishing traffic use the quay area. River ebb current can reach 1.5 kt at springs.

Setting Your Anchor

The bottom at Zumaia is primarily mud and sand with reliable holding when properly set. Note: depths given are above chart datum — with a 4–5m spring tidal range on the Cantabrian coast, always calculate your actual depth at the target tide state before entry. No Posidonia seagrass restrictions apply on this Atlantic coast, but seagrass may be present in some estuaries — anchor on bare sand or mud where possible.

1. Verify depth at target tide state — with 4–5m tidal range, charted depth alone is insufficient. Calculate HAT (highest astronomical tide) and your target entry depth using tide tables or an app.
2. Call harbour master on VHF Ch 09 — for ría and bar entries, always call before approach. Bars shift seasonally and harbour masters know current depths.
3. Drop into the current and pay out chain steadily. In tidal waters with strong river ebb, anchor into the current — not the wind. The boat will swing to the current.
4. Deploy 8:1 scope minimum — Atlantic swell and 4–5m tidal range demand more scope than Mediterranean conditions. Use 8:1 as your starting point; increase in any swell or if staying overnight.
5. Set firmly in reverse — 30–60 seconds moderate throttle astern. On mixed bottoms (sand/rock), snorkel to verify anchor is buried in sand.
6. Take a GPS position — note coordinates once set and check your swinging circle accounts for tidal current direction reversals.

Recommended anchor types: SPADE, Rocna, Delta.

Overnight Anchoring & Anchor Alarm

Overnight stays at Zumaia are feasible in stable conditions but require active monitoring — the anchorage is exposed to SW winds and swell.

Set your GPS anchor alarm to 80m radius before going below. 80m for 2–5m on mud/sand. Excellent holding inside the ría. Tidal range 4–4.5m — plan depth at LWS; ría is narrow so swinging circle matters. River ebb 1.5 kt at springs.

Tidal & Atlantic note: With a 4–5m tidal range and Atlantic groundswell that can build overnight without warning, the Cantabrian coast demands a reliable GPS anchor alarm at all times. Your boat will swing significantly as the tide reverses direction — ensure your swinging circle is clear of other boats, mooring lines, and the shore at all states of tide. The minimum recommended scope on this coast is 8:1; in any swell, increase to 10:1.

June–September. Bar crossing and narrow ría require care year-round. The Flysch cliff scenery is at its most dramatic in winter but conditions are too severe for anchoring.

Navigation Hazards

• Bar at ría entrance — call VHF Ch 09; cross at half-tide rising minimum
• Narrow ría — limited space for swinging; verify swinging circle
• Tidal range 4–4.5m — river ebb current 1.5 kt at springs
• Flysch cliffs: do NOT anchor or approach cliff base — rockfalls occur; underwater rock hazards at cliff foot
• Game of Thrones tourism brings sea kayak tours along cliffs — keep clear of kayak groups near cliffs

Rules & Regulations

• Anchoring fee: Free
• Key restrictions: Bar entry: call VHF Ch 09; cross at half-tide or above. Keep clear of fishing boat quay and ferry berth. Speed 3 kt in ría. Narrow ría — anchoring space limited; confirm swinging circle clear of other vessels.

Facilities

• Fresh water: Available
• Fuel: Not available — nearest: Zumaia town (0nm)
• Restaurant: Pintxos bars and seafood restaurants in Zumaia. The Basque pintxos (small bar snacks) here are excellent.

Skipper's Tips

1. The Flysch cliffs are best seen by dinghy or sea kayak along the cliff face (in calm conditions only — no swell).
2. The Zuloaga Museum above the cliffs holds one of the finest private art collections in the Basque Country — worth a 2-hour visit.
3. The Playa de Itzurun beach (below the Flysch cliffs) fills with Game of Thrones fans in summer — best visited at dawn.
4. Getaria (4nm W) is an easy day sail if you want to move between sites along this extraordinary coast.
