Benagil Cave in 2026-2027: access rules (boats, kayaks, boards, swimming), safety and what has changed

Updated: 10 November 2026

The Benagil sea cave (algar de Benagil), in Lagoa in the Algarve, has a small inner beach and an opening in its roof. It can only be reached from the sea. After years of crowding by boats, kayaks and swimmers, Portugal's National Maritime Authority (AMN), through the Portimão Harbour Master's office (Capitania do Porto de Portimão), issued navigation and access rules that have been in force since August 2024. This guide sets out what we could check on 10 November 2026 in news reports citing the notice and the AMN. We did not open the full text of the notice: anything we have not confirmed is marked "not confirmed". Before you go, check the rules in force on the AMN website or with the Portimão Harbour Master.

The essentials in 30 seconds

According to news reports citing Notice 019/2024 from the Portimão Harbour Master:

You may not land on or use the beach inside the Benagil cave, whether on your own or with a company.
You may not reach the caves by swimming or with any flotation aid.
You may not rent a kayak and go on your own: in the cave area, kayaks are guided only (1 guide kayak for every 6 kayaks carrying visitors).
There are limits on the number of boats and kayaks inside and on visit length. The exact figures: not confirmed.
The practical way to see the cave from inside is a boat trip or a guided kayak tour with a licensed operator, viewed from the vessel.

Notice 019/2024: what it says

What is confirmed by press reports citing the AMN:

Who: the National Maritime Authority / Portimão Harbour Master, based on the findings of the Benagil Caves Working Group (set up in 2023 and coordinated by CCDR Algarve), with Lagoa Council, the Portuguese Environment Agency (APA) and the nature conservation institute (ICNF).
When: published on 30 July 2024, in force ten working days later, on 13 August 2024. Summer 2024 was the first with restrictions.
Where: navigation within 500 metres of the coast between Vale do Lapa beach and Albandeira beach, including the caves and nearby waters.
Why: heavy boat traffic, risk of cliff collapse and protection of the Algarve Reef marine natural park (Parque Natural Marinho do Recife do Algarve – Pedra do Valado).
Fines: from 300 to 216,000 euros, according to Lusa; the highest amounts apply to tour boat operators in the most serious cases.

Kayaks, boards and SUP

What is known about non-motorised craft:

Since 13 August 2024, renting kayaks without a guide is banned in the cave area. Guided tours must have 1 guide kayak for every 6 kayaks carrying visitors.
Earlier, a Portimão Harbour Master notice of 9 September 2023 (in force on 10 September) banned "canoes, kayaks and boards" from launching or landing at Vale Centeanes, Carvalho, Benagil, Marinha, Barranquinho and Albandeira beaches, except for rescues, "until mechanisms are created" to control traffic. Whether it is still in force as published: not confirmed.
Stand-up paddleboarding (SUP): reports mention "boards" and "flotation aids" but do not name SUP. Whether guided SUP is allowed and on what terms: not confirmed. Ask the operator before booking.
In practice: do not take your own kayak or board to the cave without first checking with the Harbour Master.

Swimming and safety

AMN warnings and recent events:

In July 2025 the AMN reminded the public that swimming outside designated bathing areas is banned between Vale do Lapa and Albandeira beaches. Swimming from Benagil beach to the cave is not allowed.
On 23 May 2026 a tour boat capsized at the caves; 12 people were rescued, two with minor injuries, according to the AMN. The Portimão Maritime Police opened an inquiry; the outcome: not confirmed.
Even on a boat: wear a life jacket if the operator says so, follow the crew's instructions and avoid rough seas. If an operator cancels for weather, it is for safety.
Outside the bathing season, do not expect lifeguards at nearby beaches.

Opening times and what may change in 2027

What is not clear:

Access hours for the cave: none of the sources we checked mentions hours set by the notice. Not confirmed. Trip times depend on each operator and on sea conditions.
In May 2025, the Algarve Tourism Board told Lusa that the 2024 rules had worked and that a new notice with minor adjustments was planned: the number of boats inside and lower fines for individuals. Whether it was published and what changed: not confirmed.
In 2023 the working group studied a possible single access fee. We found no decision: not confirmed.
Rules for 2027: not yet announced in the sources we checked. Check again before you travel.

Seeing the coast on foot: the Seven Hanging Valleys Trail

According to Postal do Algarve:

The Percurso dos Sete Vales Suspensos runs about 5.7 km between Praia da Marinha and Praia de Vale Centeanes, passing Praia de Benagil and Praia do Carvalho; about 12 km if you return to the start.
With stops, allow more than two hours. It is not recommended for older people, very young children or people with reduced mobility.
Keep away from the cliff edges: some stretches are not fenced.
The trail does not give access to the inside of the cave: that is only possible by sea with an operator.

Tips for planning your visit and your stay

The practical side:

Book with a licensed tour boat operator and ask whether the trip enters the cave, how long it lasts and what happens if the sea is too rough.
Some trips leave from Portimão and others from elsewhere on the coast; compare sailing time and time actually spent at the caves.
If you stay in Lagoa or Carvoeiro, ask the property how far Benagil beach is, about summer parking and about nearby operators.
Look at the total price with taxes and cleaning and check the local accommodation (AL) registration number; if you can, book directly with the property.

If you run a property in Lagoa or Carvoeiro

What travellers typically ask AI assistants about Benagil:

Whether you can still swim to the cave or kayak there alone (no, under Notice 019/2024).
How far Benagil beach and the start of the Seven Hanging Valleys Trail are.
Total price, summer minimum stay and cancellation policy.
Keeping this clear and up to date on your website and listings avoids wrong answers. Properties in Lagoa and Carvoeiro can list on iQuota with direct booking.

How iQuota helps
