Benagil Caves Catamaran Tour from Portimão — Swim & See Algarve Sea Caves
Select participants and date
The catamaran slips away from Portimão Marina just after a low, polite swell nudges the hull—sunlight catches the whitehouses on the river and the Algarve cliffs stand like pages torn from a map. Within minutes the shoreline unfolds: little harbors, chalky ledges, and the first of the caves—arches carved by a patient Atlantic that seems intent on rearranging the coast. Onboard, the guide points out the striations in the rock and the weathered villages that watch the sea like old harbor masters.

Adventure Tips
Arrive Early for Boarding
Plan to be at Marina de Portimão 30 minutes before departure to complete check-in and secure easy boarding.
Bring a Swim Kit
If you want to swim at Praia da Marinha, pack a swimsuit, towel and a dry bag—stops are short (≈15 minutes).
Watch Weather & Cave Access
Cave entry depends on sea conditions and local authority approval; expect possible rerouting or cancellation in rough seas.
Protect Gear from Spray
Use a waterproof phone case and a strap for cameras—waves and wake throw up salt spray even on calm days.
Local Insights
Wildlife
- Audouin’s gulls
- Mediterranean monk seal (rarely visible, more often reported historically)
History
The Algarve’s coastal communities grew around fishing and salt production; many cliffs show old quarry marks from stone used to build regional towns during the 18th–19th centuries.
Conservation
Local operators follow maritime safety and access rules to protect fragile cave interiors and nesting seabirds; avoid littering and respect restricted areas to minimize impact.
