As we prepared to (finally!) leave Mexico, our friend Van took us on an excursion to the Agua Termales (hot springs) in Puertecitos about 90 km south of San Felipe. We drove about an hour south from the house, paid the 200 pesos entrance fee and turned into a pretty shabby looking settlement of houses and outbuildings. As we drove up to the springs we had a gorgeous view of the Sea of Cortez.
The springs themselves are a carefully created set of pools, built into the hillside, each slightly higher than the last. The hot springs feed directly into the top spring, bringing the water temp to a scalding level. This scalding water feeds down into the lower pools and finally directly into the ocean.
At low tide each of the pools are isolated from the ocean water and are thus all quite warm. As the tide rises the pools begin to fill with sea water and the thus become cool enough to sit in and enjoy. The trick is to move up the hill to each successive pool thus staying in the balmy water.
As noted, the highest pool which is fed directly from the hot springs and is scalding hot. The only time you can sit in this pool is when the tide is at is peak and washing enough cool water in to make the temperature manageable and it is lovely.
As you might have already guessed, as the tide turns and begins to go out, the top pool gets increasingly hot and eventually you are forced to move back down the hill to more suitable temperatures.
Since it was a full moon, the tides were very dramatic while we were there. We hopped from pool to pool while enjoying a cool beverage and, in general spent a lovely day in the Agua Termales!
Adios, Mexico y hasta la vista Sam!
