Washington snowbirds have a decision that BC and Alberta drivers mostly don't: Baja or the Sonoran coast?
The I-5 run south to Tijuana is about 1,300 miles from Seattle — shorter than the BC trip and about half the Alberta one. But Washington sits far enough east and inland that the Arizona routing to Rocky Point is also realistic, and a meaningful share of Washington drivers head there instead of the peninsula.
That choice determines which insurance territory you buy, and getting it wrong is the costliest mistake on this page. Neither covers the other.
The insurance decision, first
Baja Bound's FAQ says your Washington policy is not considered proof of financial responsibility under Mexican law, even if your US insurer claims limited Mexico coverage. Mexican federal law requires every vehicle on a federal highway, road or bridge to carry insurance covering injury and damage to third parties (Ley de Caminos, Puentes y Autotransporte Federal, art. 63 Bis), and it's enforced at accident scenes and traffic stops.
Which Mexican policy depends entirely on where you're going:
Baja Bound's quote form asks one territory question — "Are you only traveling to Baja or Sonora?" — and quotes either a Baja & Sonora policy or one for all of Mexico (Baja Bound lists a Baja & Sonora Saver discount; see the dated record on the price table).
Baja & Sonora — Baja Bound's FAQ says Rocky Point (Puerto Peñasco), San Felipe and the Cabo area all fall within its covered territories (Baja Bound FAQ).
All of Mexico — the above and everything else.
Baja Bound quoted $424.31–$530.70 for an annual (Baja Saver) policy on 4 October 2026, for full coverage on a $30,000 vehicle (2022 Toyota RAV4), Baja and Sonora only. See the price table.
The regional policy stops at the edge of Baja and Sonora. Rocky Point is in Sonora, so Baja Bound's Baja & Sonora policy covers it; Puerto Vallarta and the rest of the mainland south of Sonora need the all-of-Mexico policy. Mazatlán, for example, is in Sinaloa, which the US State Department's Mexico travel advisory lists as Level 4: Do Not Travel, and Sinaloa is outside the Baja & Sonora territory. A driver on the regional policy who crosses into Sinaloa is not covered by that policy.
If you intend to see both Rocky Point and the peninsula in one season, the Baja & Sonora policy covers both. Buy the all-of-Mexico policy if the season might continue further south.
Our Baja & Sonora vs all-of-Mexico guide covers this distinction in full.
Route A: I-5 south to Baja
The straightforward option, and the same corridor BC drivers use.
The I-5 route runs Seattle → Portland → Medford / Ashland (including the Siskiyou climb) → Redding / Sacramento → Los Angeles (through the Central Valley and over the Grapevine) → San Ysidro / Otay Mesa. Plan two long days or three comfortable ones.
Check road conditions on your route before you go, and check Oregon and California DOT conditions for the Siskiyou segment specifically before your Portland day.
Crossings: San Ysidro is the main one and sits right at Tijuana. Otay Mesa is east of it, usually less congested, and generally better on CBP's border wait times site for a loaded vehicle or a trailer.
Permits: whether your route needs a Temporary Vehicle Import Permit is covered in what you need before you drive into Mexico. The FMM visitor permit is issued by INM (INM); check its rules for a season-length stay.
Route B: I-5 to I-10 to Rocky Point
The Sonoran option, and it's a genuinely different trip.
The route runs I-5 from Seattle to Los Angeles, then east on I-10 to Buckeye, then south on SR-85 through Gila Bend and Ajo to Lukeville and on to Puerto Peñasco on Federal Highway 8. That is several hundred miles more than the Baja run.
Los Angeles → Phoenix. About 370 miles east on I-10.
Lukeville's hours: check current hours before planning a late arrival.
Permits on the Sonora route: whether this route needs a vehicle permit is covered in what you need before you drive into Mexico. Insurance is required on federal roads regardless (art. 63 Bis).
Our Rocky Point driving guide and Phoenix to Rocky Point guide cover the destination in detail. If you're drawn to Sonora but want somewhere quieter, San Carlos is the alternative.
Which route suits which snowbird
Choose Baja if: you want a long season in one place, you want the peninsula's variety (you can drive from Tijuana to Cabo on one policy), you like being able to run back to San Diego for anything you need, or you want warm winter weather in Baja Sur.
Choose Rocky Point / Sonora if: you like the RV park culture, you're bringing a boat and want Sea of Cortez fishing, or you have an existing Arizona connection and are stopping in Phoenix or Tucson anyway.
Choose the all-of-Mexico policy if: you're not sure, or the season might continue south of Sonora. The Baja & Sonora policy already covers both the peninsula and the Sonoran coast.
Where Washington drivers actually stop
On Route A (I-5 to Baja), two or three nights:
- Night one: Medford or Ashland, Oregon. Positions you to take the Siskiyous first thing in the morning, which is how you want to handle that section in winter.
- Night two: Sacramento or Bakersfield. The Central Valley day is fast and dull.
- Night three (optional): the Los Angeles or San Diego area. Skipping this means arriving at the border late, which is worse than an extra night.
- Cross in the morning for daylight driving south.
On Route B (I-5 to I-10 to Rocky Point), three nights:
- Night one: Medford or Ashland.
- Night two: Bakersfield or the Los Angeles area.
- Night three: Phoenix or Gila Bend. Positions you for a morning Lukeville crossing; check the crossing's hours.
- Cross in the morning, then it's a short drive to Rocky Point.
What a season costs to drive
Rough planning numbers, separate from accommodation:
Route A (Baja): fuel for the round trip, two to three hotel nights each way, tolls, insurance, the FMM fee, and any vehicle permit fee or deposit your route calls for (see the checklist).
Route B (Rocky Point): fuel for the longer round trip, three hotel nights each way, insurance, the FMM fee, and any vehicle permit fee or deposit your route calls for.
If you want both: Baja Bound's Baja & Sonora policy covers the peninsula and Sonora. Compare it with the all-of-Mexico quote only if the season might continue south of Sonora. It can be less costly than discovering mid-season that your policy doesn't cover where you drove.
Travel medical insurance is separate and, for a multi-month stay, frequently costs more than the auto policy. Price it early — it's the coverage that matters most if something serious happens. Get a quote from IMG if you want it; the US State Department says: "We highly recommend that you buy travel insurance before you travel" (advisory).
The honest comparison between the two routes: Baja is roughly 900 miles shorter round trip. Rocky Point wins if you want the Sea of Cortez, an RV park culture, or a stop with Arizona family built into the trip.
Timing and weather
Pick your departure date with the Siskiyou Pass forecast in mind, and check road conditions on the whole route before you go.
If you're taking Route B through Arizona, the I-10 corridor east of Los Angeles is a desert route and essentially never has winter weather problems. The consideration there is distance, not conditions.
The northbound spring trip in March or April is straightforward on either route.
Vehicle prep
You're looking at 2,600 to 3,500 miles round trip plus months of sitting in coastal salt air.
- Service before departure.
- Tires: real tread, correct pressures. The temperature range from Washington October to Baja Sur January is substantial.
- Battery: have it tested before you leave.
- Carry registration, proof of Mexican insurance, passport, and FMM together.
- Photograph the vehicle's condition before crossing.
- If you're towing a boat or trailer, verify separately that both the trailer and the watercraft are covered. Baja Bound's watercraft policy is liability cover only; physical damage and theft of the boat are not covered (Baja Bound watercraft page).
Staying connected over a long stay
Four months is long enough that phone and internet stop being a travel detail and start being infrastructure.
Your US carrier's Mexico coverage. Several major US carriers include Mexico in their domestic plans, which is a genuine advantage Washington snowbirds have over Canadian ones. Confirm the specifics before you leave, including how the plan treats extended time abroad. A plan that works for a week in Tijuana may behave differently in month three.
A local SIM or eSIM is inexpensive and worth having as a backup regardless, particularly if you'll be in areas with patchy coverage from your home carrier's roaming partner.
Internet at the rental. Ask specifically about speed and reliability, not just whether wifi exists. If you're working remotely or doing video calls with family, this is worth confirming before you commit to a season.
Coverage on the road. Download offline maps for your route before you leave, and don't build a breakdown plan that assumes a working phone.
Banking access. Notify your bank with dates, and have a second card stored separately from your wallet.
The rest of the checklist
Travel medical insurance. Your US health plan almost certainly provides little or no coverage in Mexico, and Medicare provides essentially none outside the US. Baja Bound's auto policies list medical payments for the driver and passengers, which is not the same as travel medical insurance. This is a separate purchase and it's the one people most often skip; the US State Department says: "We highly recommend that you buy travel insurance before you travel."
Prescriptions. Full supply, original labelled packaging, copy of the prescription.
Banking. Notify your bank, know your foreign transaction fees and ATM limits.
Mail and household. A four-month absence needs mail handling, and if you're leaving a house in the Pacific Northwest through winter, freeze protection and someone checking on it.
What Washington snowbirds get wrong
Buying a policy that doesn't name Sonora, then driving to Rocky Point. Baja Bound's regional policy names Baja and Sonora together; if you buy elsewhere, verify the policy names Sonora.
Driving past Sonora on the regional policy. It stops at the Sinaloa line.
Assuming their US policy extends into Mexico. It doesn't.
Assuming the vehicle permit rules decide the insurance question. They don't; federal law requires liability insurance on federal roads regardless.
Not checking Lukeville's hours. Check before a late arrival.
Not checking the Siskiyou forecast. Check conditions before you go.
Skipping travel medical insurance. Different product, and the one that matters most if something goes wrong. The US State Department says: "We highly recommend that you buy travel insurance before you travel" (advisory).
Assuming a towed boat or trailer is covered. Verify each separately.
Buying insurance at the border booth. Buying online first lets you compare terms.
If something happens
Stay at the scene, call the claims number on your policy before moving the vehicle or agreeing to anything, don't admit fault, don't sign Spanish-language documents you can't read. Baja Bound's FAQ says claims must be filed in Mexico before returning to the US (Baja Bound FAQ).
- Ask your insurer what roadside assistance the policy includes. Baja Bound's auto policies list roadside assistance and towing (Baja Bound auto page).
- Keep a printed copy of your policy in the vehicle.
Frequently asked questions
How far is Seattle to the Mexican border?
It is a multi-day drive from Seattle to the Tijuana crossing on I-5. Plan two or three days.
What Mexican insurance do Washington snowbirds need?
It depends on the destination. Baja Bound's quote form asks one territory question — are you only traveling to Baja or Sonora? — and quotes either a Baja & Sonora policy, which covers the peninsula plus Sonora including Rocky Point, or one for all of Mexico (Baja Bound quote form, 4 October 2026; see the price table).
Does a Baja policy cover Rocky Point?
No. Rocky Point is in Sonora, on the mainland. A policy from another seller that names only Baja California leaves you uninsured there. Baja Bound's regional policy names Baja and Sonora together, so it covers Rocky Point; so does the all-of-Mexico policy.
Does my Washington auto policy cover me in Mexico?
No. US policies are not valid in Mexico. Mexican law requires liability coverage from a Mexican-licensed insurer, purchased separately.
What is the route from Washington to Rocky Point?
I-5 south to Los Angeles, then I-10 east through Phoenix, then south to Lukeville and across to Sonoyta. It adds significant distance compared with the straight I-5 run to Tijuana.
Do I need a TIP for Baja or Rocky Point?
Whether your route needs a Temporary Vehicle Import Permit is covered in what you need before you drive into Mexico. Both destinations require Mexican liability insurance on federal roads, and the FMM visitor permit is issued by INM (INM).
When should Washington snowbirds leave?
Pick your departure date with the forecast in mind. The Siskiyou Pass area in southern Oregon is the main winter weather chokepoint on I-5, so check conditions before you go.
Can one policy cover both Baja and Rocky Point?
Yes. Baja Bound's Baja & Sonora policy covers both the peninsula and Sonora, including Rocky Point; an all-of-Mexico policy also covers both. Buy the all-of-Mexico policy if the season might continue south of Sonora.
The third option: the Pacific mainland
Baja and Rocky Point are the two obvious choices from Washington, but there is a third. For the mainland Pacific coast, see driving to Puerto Vallarta and driving to Mazatlán; Mazatlán is in Sinaloa, which the US State Department's Mexico travel advisory lists as Level 4: Do Not Travel. Both are outside Baja and Sonora, so both need all-of-Mexico coverage, the vehicle permit question is covered in the checklist, and both add days to the drive.
