Cala Monsul Anchorage Guide

The Anchorage

Small bay enclosed by dramatic black lava rock formations. Anchor in 3–5m in the dark volcanic sand pocket in the centre. Rock outcrops on both sides — approach slowly and check sounder. Holding is good in sand but short scope due to limited swinging room. Excellent shelter from Levante.

Setting Your Anchor

The bottom at Cala Monsul is primarily volcanic sand and rock with reliable holding when properly set. Before dropping anchor, check the DONIA app (free, Spanish Government) to confirm you are over a Posidonia-free sandy patch — anchoring on Posidonia is prohibited throughout Spain and fines can reach €600,000. Use the following approach:

1. Check DONIA app first. Open the DONIA app before approaching and identify the sandy patches suitable for anchoring. Posidonia meadows in Almería can be extensive — do not assume any bay is clear without checking.
2. Approach slowly and check your depth sounder on the way in. At 2–6m, deploy at minimum 7:1 scope (42m chain at 6m depth).
3. Drop into the wind or current and pay out chain steadily as the boat drifts back — do not allow chain to pile on top of the anchor.
4. Set firmly in reverse. Apply moderate throttle astern for 30–60 seconds. The chain should tighten and the boat should stop moving back.
5. Take a GPS bearing. Note your position once set and compare to the scope calculator to confirm adequate chain for the depth.

Recommended anchor types for this bottom: SPADE, Rocna, Bruce/Claw. See our guide to anchor types by bottom for detailed comparisons.

Overnight Anchoring & Anchor Alarm

Overnight stays at Cala Monsul are feasible but require monitoring. The anchorage is exposed to W and SW and S winds and swell.

Set your GPS anchor alarm to 55m radius before going below for the night. 55m is the maximum safe radius given the confined bay and rock outcrops on both sides. The cove is small — if another boat is present, reduce to 40m and consider whether there is enough room for two. Do not anchor here in W or SW swell.

On this coast, the Levante (E/NE) can arrive with little warning and accelerate dramatically around Cabo de Gata headland. If you are anchoring in an exposed bay and Levante is forecast overnight, set a conservative alarm radius and be prepared to depart or move to a more sheltered position. The Safety Anchor Alarm app will wake you the moment your boat drifts — giving you time to react before the situation becomes dangerous.

May–July and September–October best for calm overnight stays. August Levante can arrive suddenly — monitor closely. Winter storms make this bay dangerous; suitable for day use only Nov–Mar.

Navigation Hazards

• Rock outcrops on both sides of cove entrance — approach dead centre and slowly
• Very limited swinging room — maximum 3–4 boats; do not attempt if full
• Exposed to W/SW — any swell from this direction makes it untenable; exit immediately
• No night lighting — approach or departure in darkness not recommended

Rules & Regulations

Cala Monsul lies within or adjacent to the Cabo de Gata-Níjar Natural Park (Parque Natural). This is a protected natural area but not a marine reserve — there is no entry fee and free anchoring is permitted in most bays. However, Posidonia protection rules apply in full: anchoring on Posidonia oceanica is prohibited throughout Spain and subject to severe fines.

• Anchoring fee: Free
• Maximum stay: 3 days
• Key restrictions: Within Cabo de Gata-Níjar Natural Park. No anchoring on any Posidonia — use DONIA app. Cove capacity limited; do not anchor if no swinging room.
• Posidonia: Anchoring on Posidonia oceanica is prohibited throughout Spain. Fines up to €600,000 in the most sensitive zones. Use the DONIA app before every anchor drop.

Facilities

• Fresh water: Not available on site — Almería is the driest region in Europe. Arrive with full water tanks. Nearest water: San José (4nm)
• Fuel: Not available — nearest: San José (4nm)
• Restaurant: None — nearest provisions at San José (4nm)
• Provisions: None on site — San José (4nm)

Skipper's Tips

1. Approach from the NE, hugging the 6m depth contour to avoid isolated rocks on the S side of the entrance.
2. Use a bow anchor and stern anchor or stern line to the rocks to reduce swing in the confined space.
3. Snorkel the lava formations — the underwater volcanic landscape is extraordinary; visibility is typically 20m+.
4. Best in the morning before the afternoon Poniente builds — leave by 13:00 if W is forecast.
5. The beach is reachable by 4x4 from San José — mornings are quiet, afternoons can be busier in July–August.
