Swim in San Alfonso del Mar’s Lagoon | Chile
Look across an artificial lagoon so long that swimmers share the water with small boats. San Alfonso del Mar in Algarrobo held the world record for largest swimming pool by area when it opened, although larger pools have since taken that title. The original name survives in bucket lists, but the current experience deserves the accurate history. This is a private residential resort rather than a public attraction with a simple day ticket. Access normally comes through staying in or renting an apartment, and swimming zones, maintenance periods and resident rules may limit how the lagoon is used. The Pacific beside it is scenic but cold and entirely separate from the controlled pool. Confirm in writing that a specific booking includes guest access to the lagoon and ask which areas permit swimming during your dates. Treat accommodation cost as the admission route and avoid turning up expecting to pay at a gate. Add this to your list and swim across a record-breaking piece of Chilean resort engineering.
