Introducing the Eco – Try Dive Experience in Sesimbra
If you’re considering dipping your toes into the underwater world without committing to a full certification, the Eco – Try Dive offered by Anthia Diving Center in the Setubal District, Portugal, is a fantastic option. Priced at around $103.18 per person, this roughly 4-hour introduction to scuba diving is perfect for beginners or those curious about eco-conscious diving.

With a consistent rating of 5 stars from 8 reviews, it’s clear this experience resonates with many travelers.
What I love most about this experience is the dedication to safety and professionalism—each instructor is paired with just two participants, ensuring personalized attention and peace of mind. Plus, the focus on environmental preservation gives this activity a meaningful edge; you’re not just exploring marine life but actively contributing to its protection. A second highlight is how Sesimbra’s waters offer remarkable clarity and a diverse abundance of species, making it a visual treat.

However, keep in mind that this experience is tailored to those with moderate physical fitness and able to follow basic safety instructions.
