Can we swim inside Benagil Cave or at other stops?

Swimming is possible at Algar Seco's natural pools and designated beach stops, weather and captain approval permitting. Benagil Cave itself is viewed from the boat; swimming is typically in surrounding waters and natural formations rather than inside the cave.

Is this tour suitable for non-swimmers or people with mobility concerns?

The tour is boat-based, so you don't need to be a strong swimmer to participate. However, access to Portimão's boat launch should be confirmed with the operator. Swimming stops are optional.

What's included in the EUR 500 private tour price?

The price covers the 2-hour private boat journey, experienced captain, access to multiple caves and beaches, and stops for swimming and sightseeing. Confirm what's excluded (e.g., drinks, snacks, insurance) when booking.

How many people can join a private tour?

Private tours accommodate small groups; the exact capacity depends on the boat. Confirm group size limits and pricing for larger parties when booking.

Will we definitely see dolphins?

Dolphin sightings are possible but not guaranteed. The captain will advise on sighting likelihood based on seasonal conditions and sea activity on the day of your tour.

Pack sunscreen, a hat, sunglasses, a towel, swimwear, water, and a light jacket or rash guard. Waterproof bags are helpful for phones and valuables. Bring motion sickness medication if you're prone to seasickness.

our guide Zara really knew their stuff and the bit at the end nobody expects was the highlight. Used it for our summer trip so it wasnt too busy. Worked great for a solo traveller like me, and ran the full 4 hours promised, and last day of the trip. Would book again no question.
