Accommodations are limited. Most hotels, restaurants, and businesses in Puerto Penasco have English-speaking personnel. Fresh seafood, brought in daily, is on every menu, as well as Mexican specialties. You can buy fresh shrimp and seafood to take home at fish markets along the ocean front in the Old Port. Some of them have small outdoor restaurants.
Shopping is plentiful.
There are grocery stores, fruit stands, hardware stores, and of course, lots of curio shops. Puerto Penasco has beautiful beaches open to the public. The best swimming is from May through October. Boating, sunbathing and water sports are the popular activities. It's not necessary to convert your dollars into pesos since virtually all businesses use U.S. dollars.
