What to Pack for San Carlos: The List Mr. Playas Wishes He'd Had Earlier
The Sonoran desert meets the Sea of Cortez in San Carlos. That combination means intense sun, warm water, rocky terrain, and temperature swings between 95°F afternoons and 65°F evenings in winter. Packing for San Carlos requires thinking about all of it.
Sun Protection — Non-Negotiable
- SPF 50+ sunscreen — bring more than you think. San Carlos stores carry sunscreen but selection is limited and the price is triple what you pay at home.
- Reef-safe sunscreen specifically for snorkeling — mineral (zinc/titanium) options only in the water.
- Wide-brim hat or surf hat with UPF protection.
- UV-blocking sunglasses — polarized preferred for water activities.
- Long-sleeve rash guard or UPF shirt for extended time on the water.
Clothing
- Two swimsuits minimum — one dries while you wear the other.
- Light linen or synthetic fabric shirts and shorts.
- A light jacket or fleece for November through March evenings (temperatures drop to 55–65°F).
- One pair of closed-toe shoes with grip for hiking Cerro Tetakawi and Nacapule Canyon.
- Water sandals or Tevas for rocky ocean floor at Piedras Pintas.
Water and Outdoor Gear
- Reusable water bottle — minimum 32 oz.
- Snorkel mask and snorkel — essential for Piedras Pintas.
- Dry bag for boat excursions and kayaking.
- Headlamp for sunrise hikes or sunset Tetakawi descent.
- Waterproof phone case for water activities.
Money and Documents
- Mexican pesos in cash. Many restaurants are cash-preferred or cash-only.
- Passport — required for the US-Mexico border and Isla Tiburón permits.
- Mexican auto insurance documentation if driving.
- Tourist Vehicle Permit (TIP) if driving a US-registered vehicle beyond the border free zone.
- Credit card for hotels, marina restaurants, and dive operators.
What to Buy There, Not Bring
Bottled water (buy cases at the Guaymas Walmart on the way in), beer and drinks, local food, snacks.
What to Leave Home
Formal clothes — San Carlos is casual, full stop. Lots of books — you will not read as much as you think. Excessive luggage.
Every year someone arrives in San Carlos in February thinking winter means mild sun. The altitude is sea level, the reflection off the water is intense, and SPF 15 is not a plan. The best sunburn stories from San Carlos involve people who thought they were fine. Pack SPF 50+, pack a lot of it, and apply it before you leave the room. .
