As we drove inland toward the lakes northwestern shore, red dust kicked up off the rutted dirt road.

At 12,500 feet above sea level, the air felt thin and crisp.

On the horizon, the Andes Mountains reared up into the sky.

After the traffic-choked streets of Arequipa, the first thing I noticed was the quiet.

The interiors are decorated in a contemporary style and accented with wood-and-cowhide chairs and wool rugs.

The water below us was cold and clear.

It was a quiet, eerie place.

The next day we left Titilaka around noon, taking the hotel van to a port north of Puno.

Do you think people could have sailed across the Pacific on one of these?

(Cars arent allowed on the island; people get around on steep stone footpaths.)

As we walked, we saw farmers working the terraced hillsides with hand tools.

In the evening, we hiked to Las Velas,an unassuming, candlelit restaurant that overlooks Kona Bay.

Chef Pablo Callsaya steamed whole lake trout inmuna,which he called the special touch.

We arrived in Yumani just in time to catch the ferry to Copacabana.
