Discover Sesimbra’s hidden beaches and marine life on a 2.5-hour boat tour featuring snorkeling, scenic views, and unspoiled coastal landscapes.
Exploring Portugal’s coast often conjures images of popular spots like Lisbon or Porto, but Sesimbra offers something a little more secret and special. This boat tour, focusing on unspoiled beaches and hidden bays, promises a relaxed yet adventurous way to see the coast’s lesser-known natural beauty. It’s a well-rounded experience packed with snorkeling, scenic views, and local charm, all at a price that’s quite reasonable considering the quality.
What we particularly love about this tour is its focus on authentic encounters with nature. You’ll get to explore quiet beaches that remain untouched by crowds, enjoy the calm waters ideal for snorkeling, and even sip regional drinks while soaking up the scenery. The one potential consideration? The tour lasts just 2.5 hours, so if you’re after a full-day adventure, you might want to combine it with other activities. Still, for those seeking a relaxing, nature-filled escape, this tour hits the spot. It’s perfect for travelers who enjoy small groups, personalized attention, and discovering Portugal’s coast off the beaten path.
