San Alfonso del Mar

San Alfonso del Mar is the world's second-largest swimming pool, with an area of 80,000 m2 (860,000 square feet). When it was completed in 2006, it was ranked first. In 2015, however, the largest swimming pool was won by Citystars Sharm El Sheikh in Egypt.

There are a few things to keep in mind if San Alfonso del Mar is on your bucket list. For starters, despite the fact that it is heavily advertised to foreigners, you may only use this pool if you are staying at the resort.

San Alfonso del Mar is an apartment complex with privately owned condos, rather than a hotel with rooms. So, if you want to come, you'll have to rent one of the condominiums from the owner directly. Second, the enormous pool here is not suitable for swimming. In actuality, it's a place where you can rent paddleboards and kayaks for water activities.
