Puerto Peñasco lies about 400 km from Hermosillo, a 3.5 to 4 hour drive via Federal Highway 15 to Santa Ana and then Federal Highway 8 north through Caborca, or a similar-length trip on a direct Tufesa coach. The town sits on the Sea of Cortez near the Gulf of California's northern reach and serves as the gateway to the El Pinacate y Gran Desierto de Altar Biosphere Reserve, a UNESCO World Heritage site of volcanic craters and towering sand dunes about an hour inland. Given the driving distance, an early departure from Hermosillo is essential; a full day covers a morning stroll along the Malecón Kino and Playa Bonita, then a stop at CEDO (Centro Intercultural de Estudios de Desiertos y Océanos) to learn about the upper Gulf's marine ecosystem, followed by an afternoon at the El Pinacate visitor center exploring the Cerro Colorado crater rim trail or the dune fields near El Elegante crater. Food options include fresh shrimp and fish at the Malecón's seafood market and restaurants along Boulevard Kino. Because of the round-trip distance, an overnight stay in Puerto Peñasco is strongly preferable to attempting both the coast and the biosphere reserve in a single day, and October through April avoids the harshest desert heat for hiking around the craters.

Tips for visiting
- Rent a car for the trip, since reaching the El Pinacate visitor center requires driving beyond town
- Book a Tufesa coach from Hermosillo's Central de Autobuses if not driving, though it adds travel time
- Plan an overnight stay rather than attempting the round trip and the reserve in one day
- Bring plenty of water and sun protection for the crater rim trails, which have little shade
- Check the El Pinacate visitor center hours in advance, as reserve access closes at a set time each afternoon
