The advantage of Penasco are: 1. It's beautiful 2. It's close. Are there prettier beaches, yes, but it takes at least a day to get there, and they're expensive. Penasco hits the sweet spot for us in Tucson/Phoenix! First trip to Sea of Cortez- 1970. Purchased land/built home 25 years ago in 1998. With all the great memories with kids, family, friends, no regrets.
