Cascais: Open Water Swimming and Hiking Experience — A Genuine Adventure in Portugal
Imagine spending a day exploring Portugal’s stunning coast and natural parks, swapping the usual sightseeing for a more active, authentic experience. That’s exactly what the Cascais Open Water Swimming and Hiking tour offers. It’s a six-hour journey blending the thrill of swimming in the crystal-clear Cascais Bay with the serenity of hiking in the Sintra Cascais Natural Park. The tour is thoughtfully designed to showcase some of Portugal’s most beautiful landscapes, all led by knowledgeable guides who make safety and fun their priorities.
What I love about this experience is how it balances adventure with authenticity. First, the certified swimming coach makes you feel confident whether you’re a seasoned swimmer or trying open water swimming for the first time. Second, the scenic lunch with views of the sand dunes in Cresmina is a genuine highlight, offering a peaceful moment to relax and take in the natural beauty. The only caveat? If you’re not comfortable in open water or have mobility challenges, this might not be suitable, as it’s geared toward active participants comfortable in water and on foot.
Another aspect worth considering is timing—since the experience varies depending on availability and the group’s pace, it’s wise to check the starting times and book in advance. Overall, it offers a memorable mix of physical activity, scenic sights, and local flavor that’s hard to beat.
