“Solo traveller. This tour was absolutely fantastic. I went for the 12:30 appointment in the second week of October and the dolphins were still there. We were able to see common dolphins and bottle nose dolphins! Our skipper (Diogo) and our marine biologist (Rui) were absolutely fantastic! They allowed us to see everything and the weather was great. I would recommend bringing a light jacket or something with you as you are whipping over the sea at great speed so it does get a bit cold. The Seacret team were great and check in was really easy. I’d highly recommend going on this tour! It’s well worth the money! 10/10”
