9.Sesimbra: Arrábida and Espichel Caves Tour and Snorkel

★★★★★★★★★★4.5 · 20 reviews · 2.5 hours

Set out from Sesimbra with a local guide such as Mariana or Tiago to see the Tamboril and Frade grottoes, Arco da Pombeira, marine-eroded rock, and quiet bays. You will have time for swimming and snorkeling, then finish with a taste of local Moscatel wine.

“Super skuffet over at snorkelstoppet på en halv time var 10 minutter et sted hvor vandet var helt uklart og man ingen ting kunne se. Det var et badestop - men ikke til snorkeling. Desværre var snorkeling den primære grund til at vi havde booket denne tur. Grotter har vi set masser af gange før. Vi sejlede endda forbi flere steder som guiden specifikt udpegede til at være fantastiske snorkelsteder. Også skuffet over at turen hed lille gruppe - maks 8 personer, vi var 9 i en båd som slet ikke lignede den på billederne, og hvor man sad meget dårligere.”
