Hello Every body,
I am masterofscience and I dive most of the time in Chile. Frequenly I go to Los Molles (three hour from Santiago) or Quintay (one hour and half from Santiago). Chile is a very large country, so there is a lot of beachs. The problem of the ocean is the temperature of the water, because is very cold. Normally we use wet suites of 7mm thickness (13 mm in the trunk) or dry wet (only the people who dives every weekend).
There is a lot of place to dive, but the good one are far away from my home (Easter Insel, Playa Blanca, etc)
Best Regard
