I wonder.... is it actually a salt water pool, with water circulated from the ocean? It's hard ot believe it would be a freshwater pool.... the filtration system would have to be gigantic.

What I found interesting is that it cuts the property off from the ocean. If you want to get to the ocean you could have up to a half kilometre to walk just to put you toes in the ocean. I assume that there is some reason swimming in the ocean isn't appealing.

Yes.

Chile's monster pool uses a computer- controlled suction and filtration system to keep fresh seawater in permanent circulation, drawing it in from the ocean at one end and pumping it out at the other.

From Wikipedia (http://en.wikipedia.org/wiki/San_Alfonso_del_Mar):


San Alfonso's pool is 1,000 meters (3/5th mile) long and up to 35 metres (115 ft) deep. The pool covers an area of 7.7 hectares (19 acres) that holds 250 million liters (66 million gallons) of seawater.[2] (http://en.wikipedia.org/wiki/San_Alfonso_del_Mar#cite_note-rec-1)[3] (http://en.wikipedia.org/wiki/San_Alfonso_del_Mar#cite_note-2)[4] (http://en.wikipedia.org/wiki/San_Alfonso_del_Mar#cite_note-deep-3) The pool, developed by Chilean company Crystal Lagoons (http://en.wikipedia.org/w/index.php?title=Crystal_Lagoons&action=edit&redlink=1), uses water pumped, filtered, and treated from the Pacific Ocean (http://en.wikipedia.org/wiki/Pacific_Ocean) to supply to the pool.

That's amazing. It looks like (in essence) they dammed off the cliff face in front of the hotel, cement-faced the interior (or with something impermeable) and filled it up. Quite a project, especially the 35 meters depth. The water pressure down at the bottom there must be significant. I wonder if it leaks?

Shamrock Hilton in Houston, TX has, or had a pool big enough to water ski in.
Larchmont YC has a (smaller) salt water pool, affectionately called The Bay of Pigs.

I wonder if the depth comment meant width and not depth as we think of it...there is consistent water color and not the deeper color I would expect as the depth increases.

According to this web site:http://www.earthdocumentary.com/san_alfonso_del_mar_chile.htm They keep it 9C above the ocean temp.
