What you need to cross at Lukeville and drive to Rocky Point (Puerto Peñasco) - passports, the FMM tourist permit, Mexican auto insurance, and what still trips travelers up.
To drive to Rocky Point you need three things: a valid U.S. passport book or passport card, a Mexican auto insurance policy and an FMM tourist permit. You do not need a vehicle import permit (TIP), because Puerto Peñasco sits inside the Sonora Free Zone.
Rocky Point is the closest saltwater beach to Phoenix and Tucson, which makes it one of the easiest international trips in the Southwest. It is roughly an hour south of the border once you clear the crossing at Lukeville. Easy, though, is not the same as no paperwork. Here is exactly what to bring, what has changed recently, and where travelers still get tripped up.
Your U.S. or Canadian auto policy does not provide the liability coverage Mexico requires. Mexican law requires liability coverage issued by a Mexican insurance company, and if you are in an accident without it, you can be held financially responsible on the spot, regardless of who was at fault.
If Rocky Point is a regular trip for you, look at the Baja & Sonora Saver first. It is our discounted six month and annual policy built for frequent travelers and residents, and it covers Sonora as well as the entire Baja Peninsula. That means it works whether you are heading to Puerto Peñasco this weekend or down Highway 1 next month. There are no travel club fees, coverage comes from 'A' rated carriers, and it pencils out for anyone spending more than about two to three weeks a year in Mexico.

Keep a printed copy of your policy in the glove box and a photo on your phone. Sonoyta traffic officers and Guardia Nacional at highway checkpoints will occasionally ask, and a printed policy ends the conversation faster.
Every traveler, including children, needs a U.S. passport book or passport card, a Canadian passport, or another accepted travel document. Two notes are worth knowing:
Practically speaking, the document matters most on the way home, because CBP requires it to re-enter the United States at Lukeville.
The Forma Migratoria Múltiple (FMM) is the tourist permit issued by Mexico's Instituto Nacional de Migración (INM). Mexican immigration law requires it for every foreign visitor entering Mexico. There is no "tourist zone," no 72 hour exemption, and no free pass for a weekend beach trip.
| Length of Stay | Cost | Maximum Stay |
|---|---|---|
| 6 days or less | Free | 6 days |
| 7 to 180 days | $983 MXN (~$55 USD) | 180 days |
Here is where travelers get confused. Enforcement at Sonoyta has historically been inconsistent. Mexican officials announced stepped up FMM enforcement for Rocky Point travelers back in 2025, and INM staffs an assistance team at its Sonoyta office, but whether you are asked for the permit still depends on the officer and the day. That inconsistency has convinced a lot of people the permit is optional. It is not. Highway checkpoints exist, and showing up without a valid FMM can mean being turned around, or being logged in the system as a repeat offender.
Our full walkthrough covers the online application, the border procedure, multiple entry rules, and what happens at checkpoints. Read it here: Guide to the Mexican Tourist Card (FMM).
Apply online in advance, print the form and receipt, then get it stamped at the INM office in Sonoyta, just west of the highway after you cross. An unstamped FMM is not a valid FMM.
Puerto Peñasco is inside the Sonora Free Zone, so no Temporary Vehicle Import Permit is required to drive there. The same is true for Caborca, Magdalena, Santa Ana, Hermosillo, Bahía de Kino, Guaymas and San Carlos.
You only need to think about a permit if you are heading deeper into Sonora or on to mainland Mexico. If you are staying in Sonora but traveling beyond the free zone, you will want a Sonora Only permit. If you are crossing into mainland Mexico, you need a standard TIP. Both are explained here: Vehicle Permits for Mexico and Sonora Only Vehicle Permits.
Toys count too. Trailers, ATVs, side by sides, boats and jet skis are a big part of a Rocky Point trip, and they need their own coverage. Add them to your policy when you request a quote.
Nearly everyone drives the same way. Head south on Arizona State Route 85 through Why, Arizona, to the Lukeville Port of Entry, then into Sonoyta, Sonora, and south on Mexico Federal Highway 8 straight into Puerto Peñasco. It is roughly 60 miles from the border to town, about an hour, and about three and a half to four hours total from Phoenix.
Lukeville is not a 24 hour crossing. It typically operates 6 a.m. to 8 p.m. daily, with occasional extended hours around holiday weekends. Plan your return with that in mind, and check current hours and wait times on CBP's Border Wait Times site before you leave. An 8 p.m. closure means a long detour if you miss it.
This one surprises first timers. Cell phone use is strictly prohibited in the Mexican customs inspection area. It is not discouraged, it is banned. Put the phone down and out of sight before you reach the inspection booths, and tell your passengers to do the same. Officers will call it out, and it is an easy way to turn a 30 second wave through into a full inspection.
Northbound at Lukeville you will need your passport or passport card and a declaration of what you are bringing back. Shrimp is legal and worth the cooler space. Certain fruits, vegetables and plants are not. See Returning to the U.S. for the current list.
| Item | Required? | Notes |
|---|---|---|
| Passport book or passport card | Yes | The card is fine for land crossings |
| FMM tourist permit | Yes | Free for 6 days or less, and get it stamped |
| Mexican auto insurance | Yes | U.S. and Canadian policies are not valid |
| Vehicle import permit (TIP) | No | Sonora Free Zone |
| Current vehicle registration | Yes | In your name or an immediate family member's name |
| Lender letter of permission | If financed | Requires proof of Mexican insurance |
| Coverage for trailers, boats, ATVs | If towing | Add them to your policy |
Yes. A U.S. passport book or passport card is required to re-enter the United States at Lukeville, and you will need it to obtain your FMM in Mexico. A passport card is sufficient for driving.
Legally, yes. Mexican immigration law requires an FMM for all foreign visitors regardless of trip length. For stays of six days or less entering by land it is free, so there is no financial reason to skip it. Enforcement at Sonoyta is inconsistent, but a highway checkpoint without a valid permit is not a problem worth having.
No. Puerto Peñasco is in the Sonora Free Zone, so no Temporary Vehicle Import Permit is required. You would only need one to travel beyond the free zone or into mainland Mexico.
No. Mexico requires liability coverage from a Mexican insurer. Some U.S. policies extend limited physical damage coverage a short distance into Mexico, but none of them satisfy the Mexican liability requirement.
A short term policy for a weekend is inexpensive. If you go more than a couple of weeks a year, the Baja Saver six month or annual policy, valid in Sonora and both Baja states, usually costs less than buying trip by trip.
Lukeville generally operates 6 a.m. to 8 p.m. daily and is not open 24 hours. Verify current hours before you travel, especially if you are planning a late return.
No. Phone use is prohibited in the Mexican customs inspection area. Put it away before you reach the booths.
Yes, and no import permit is needed within the free zone. Do insure them, though. Towed units and watercraft need to be listed on your Mexican policy to be covered.
