Benagil Cave 2026: Rules and How to Visit It Properly
8 min read
Benagil Cave (the Algar de Benagil, in the municipality of Lagoa, Algarve) is one of the most photographed sights in Portugal: a cavity in the cliff with a small sandy beach inside. Precisely because of that, since 2024 it has had strict access rules, issued by the Harbour Master’s Office of Portimão: you may not swim in, you may not land on the sand, and visits are measured in minutes.
This guide sums up what the official edicts say (each one linked), what is allowed and what is not, and how to plan a legal, safe visit. It is not legal advice: if you will operate a boat, always check the current text on the National Maritime Authority’s website.
Which rule applies, and to whom
The visit is governed by Edital 019/2024 of the Harbour Master’s Office of Portimão (30 July 2024), amended by Edital 009/2025 (2 July 2025). According to the text itself:
- Area: the Benagil cave system, between Vale do Lapa beach and Albandeira beach, and the adjoining water.
- Who it affects: the general public, maritime-tourism operators, recreational vessels and any navigation that comes within 500 metres of the coast in that area.
- Why it exists: the edict cites the risk of cliff falls (the inner beach lies inside a risk strip), congestion of boats and kayaks, accidents between them, and protection of the Algarve Reef – Pedra do Valado Marine Natural Park, where the caves lie.
What is prohibited
For motor boats and for kayaks, boards and canoes alike:
- Landing on or using the beach inside the algar (or any similar cave).
- Entering the algar by swimming or with flotation aids.
- Diving, with a tank or freediving, inside the caves and their access areas (except authorised research).
- Fishing, from shore or from a boat, near or inside the cave.
- Night navigation (between sunset and sunrise).
- Access in visibility below 1,000 metres.
- Renting or using kayaks, SUPs and canoes without a guide in this area (the ban on unguided rental was added by Edital 009/2025).
How long and how many: the limits
| Motor boats | Kayaks, SUPs and canoes | |
|---|---|---|
| Time inside the algar | 2 minutes | 8 minutes per group |
| Simultaneous | Up to 5 boats at a time (Edital 009/2025; previously 3, or 1 if over 12 m) | Up to 14 craft at a time (previously 7) |
| Entry and exit | West (poniente) side only | East (nascente) side only, in single file with a U-turn |
| Organisation | Skippers assess conditions and may abort the visit | Groups of 6 craft with 1 guide (with first-aid and basic life support training) |
Other obligations in the edict:
- Life jackets for the whole visit, and helmets near the rock-fall risk strips.
- Reduced speed when approaching the coast and a course perpendicular to the shoreline; avoid several boats piling up in one place.
- Unregistered paddle craft may only operate between 100 and 300 m from the water’s edge.
- Kayak guides must carry a whistle, a knife, a first-aid kit, a tow line and a means of communicating with shore.
- Companies running these trips must be recognised as tourist entertainment («nature tourism») under Portuguese law.
What changed with Edital 009/2025
Edital 009/2025 (2 July 2025) amended the 2024 text in four ways that matter to visitors: it raises the simultaneous limit (up to 5 motor boats, previously 3, and up to 14 paddle craft, previously 7), requires paddle craft used in maritime-tourism activity to carry the company’s name and a sequential number on both sides (inflatables may be identified through their life jackets), bans tours and rentals of paddle craft without a guide, and adds a separate fine bracket for private individuals who do not use protective equipment (see below).
How much the fines are
The edict does not set a single figure: each infringement has its own range. These are the ones in the official text (Instruction 7 of Edital 019/2024, as amended by 009/2025):
| Type of infringement | Fine |
|---|---|
| Most prohibitions and obligations: swimming in, landing, access in poor visibility, diving, night navigation, fishing, using the wrong entrance, and life jackets and helmets when an operator or crew member breaches them (our reading) | €2,200 to €44,000 |
| Not using protective equipment (life jacket and, near rock-fall risk, a helmet) when done by a private individual (bracket added by Edital 009/2025) | €25 to €20,000 |
| Paddle craft outside the 100–300 m strip from the shore | €300 to €12,000 |
| Kayak guide without a means of communicating with shore | €300 to €7,480 |
| Operating without recognition as tourist entertainment (minor environmental offence) | €200 to €36,000 |
| Serious environmental offence (for example, excess noise) | €2,000 to €216,000, with possible additional penalties |
You often read that «the fine is up to €216,000» for swimming or landing: that is not what the edict says. That maximum belongs to the serious environmental offence; the bans on swimming and landing carry a range of €2,200 to €44,000.
Limitation: Edital 009/2025 only reproduces what it amends (the rest appears as «(…)»), so the exact allocation of each infringement to a bracket should be checked against the Harbour Master’s consolidated text.
How to visit the cave legally
The two ways the edict provides for:
- By boat, with a maritime-tourism operator. The visit inside lasts 2 minutes and is made without landing.
- By kayak or SUP with a guide, in a group, entering through the east side for a maximum of 8 minutes.
Before booking, ask the operator: whether it is authorised as tourist entertainment, whether it provides life jackets (and helmets where needed), whether the group size respects the maximum of 6 craft per guide, and what happens if the day does not allow the visit.
Avoiding misunderstandings when you book
The edict applies to every vessel, private or touristic: there is no «exclusive access» to the cave and no extra time for anyone. If the advert for a trip or a charter promises something different, ask before booking:
- What exactly happens at the cave: the boat visit inside the algar lasts 2 minutes and without landing. If the programme includes swimming, snorkelling or paddleboarding, ask where they happen (they cannot happen inside the algar or its access areas).
- Whether paddle craft are used (SUP, kayak): they must go in groups of 6 with a guide trained in first aid.
- Whether life jackets (and helmets where needed) are provided.
- Whether the company is recognised as tourist entertainment.
When the visit is not possible
The edict makes access conditional on weather and sea conditions allowing it and on there being no Notice to Mariners that bans or limits the activity. You also cannot enter with visibility below 1,000 metres. In practice the visit may be cancelled for swell, wind or fog, so keep your dates flexible.

Frequently asked questions
Can you swim into Benagil Cave?
No. Access to the inside of the algar by swimming or with flotation aids is prohibited and fined between €2,200 and €44,000.
Can you land on the beach inside the cave?
No. Landing and using the sand inside is prohibited, for boats and kayaks alike. The beach lies in a rock-fall risk zone.
How long can you stay inside?
Motor boats, 2 minutes. Kayak or SUP groups, up to 8 minutes.
Can I rent a kayak on my own?
Not in this area. Edital 009/2025 does not allow tours or rentals of kayaks, SUPs or canoes without a guide. Groups are 6 craft with one guide.
Can you go at night?
No. Night navigation (between sunset and sunrise) is prohibited in the area.
Why do some websites say «5 to 10 minutes»?
Because they repeat old or approximate figures. The current edict sets 2 minutes for motor boats and 8 minutes for kayak or SUP groups.
How much does breaking the rules cost?
It depends on the infringement: most are €2,200 to €44,000; a private individual not using a life jacket or helmet faces €25 to €20,000; serious environmental ones go up to €216,000.
