The Tehuacalco Ruins tour was the highlight of our trip. This recently and partially excavated site is about an hour and a half from Acapulco. It's high in the mountains and cooler than in Acapulco. Our van driver and guide Rubin, while in his 70's, was chipper and faster than any of his guests. The walking is not recommended for anyone with mobility problems but if you get tired there is no problem with stopping any where along the route. You can wait until the group returns. Water was provided but no food is available so you might want to bring along a snack. The tour was longer than advertised but we saw much more of Mexico than those who chose to shop in town. It's a highly recommended tour.
