Tres Rios (the new name for Estrella Mountain Golf) is a favorite of our group. We like the conditions of the greens and fairways. We think that the conditions are one of the best in the west valley. Also, we find the fees to be a value. The course tends to be 'flat' and straight. Also, it is not unusual for errant balls to come into your fairway as the holes are close to each other. Many greens are slightly raised and sloped. Best for the long - straight hitter who has great touch around the greens and bunkers.
