What an absolute treat

My friends and I had an absolutely fantastic afternoon sailing along the Barcelona coastline earlier in the month. Dave was a brilliant and knowledgeable host, extremely welcoming and we couldn't have asked for better weather. It was such a treat being able to swim in the clear waters alongside the boat. I would highly recommend this experience to all as it was the highlight of my Barcelona adventure. Thanks again Dave!

Highlight of our honeymoon!

My wife and I had a lovely evening sailing with Dave. He was very accommodating and friendly. The boat itself is very charming and easy to find in Port Olimpic. The views of the Barcelona shore are unreal at dusk. Make sure you bring some food and drink for your trip. Dave even let us swim out in the open ocean as the sun set over the city. If you plan on making it out to Barcelona, do not skip this opportunity. I can't say enough about how amazing this experience was. Thank you Dave!

Lovely way to spend a couple of hours

Our group of 11, including 6 children aged 9-12, had a wonderful trip. Captain Danny was very friendly and let all the kids have a go at skippering the boat, which was one of their highlights of visiting Barcelona!

You want to go sailing? Classic Sail Barcelona is the perfect provider!!

I wanted to surprise my fiancée for her birthday - the booking of Gemini with Skipper Dave was the perfect gift and an incredible experience. We took the Sunset Tour which was a picture perfect trip with blue sea, a romantic sunset and a refreshing swimming stop. Gemini is a beautiful and very well maintained sailing boat, with a nice history (built in 1947). Skipper Dave couldn't have been a nicer host with a friendly smile and loads of cool insights into sailing.

Private Sunset Cruise

Booked this for our anniversary, and had a really amazing evening. The boat is beautiful and skipper Dave is really helpful and friendly, all we had to do was enjoy the trip. My girlfriend was amazed by the experience and it was the perfect way to celebrate a romantic evening and escape the city.
