Take the bus to the end of the road and you have arrived at Boca De Tomatlan . . . we think that meant Tomato Land, but we did not see any tomatoes. What we found was a bay in a small village and an awesome beach with a seaside cabana to laze around all day long.
The staff at the cabana will serve you all day long, bring you drinks, food, whatever you wish while you lay around by the shore.
This was an awesome find. We had a great time down there. We had fresh fish cooked over an open fire with chips and salsa and you could order a variety of drinks, I kept mine in a bottle -- Pepsi as this was away from the main city so you don't quite no about the water . . .
We never did have any problems with Montezuma's Revenge, so they must do a pretty good job of sanitization down there.
