RV Dump Stations In Sonora -- Find Sani-Dumps Online

Sonora is the Mexican mainland destination most American and Canadian RVers actually visit, because it hosts the coastal towns of Puerto Peñasco, San Carlos, and Kino Bay that sit inside the Sonora Free Zone and skip the temporary vehicle import permit hassle entirely. We track several dump stations across the state, with some of them free and the remaining a portion% charging a fee. Like the rest of Mexico, the network is built around private RV parks rather than municipal facilities, so most of the paid sani-dump stations are bundled with overnight stays at established parks.

The sanitary dump station landscape here concentrates in three coastal areas. Puerto Peñasco (Rocky Point) is the closest Mexican beach town to most US snowbirds, just 100 km south of the Arizona border, and has the densest cluster of RV parks and sani-dumps in the state. San Carlos on the Sea of Cortez further south is the established expat beach town with mature RV infrastructure. Kino Bay is quieter and more rustic. Inland options are limited; Hermosillo has basic services but isn't really an RV destination.

The Sonora Free Zone is the critical advantage for Sonora travel. It covers the western part of the state from the border south to Empalme (just south of Guaymas), bordered inland by Highway 15. Vehicles staying inside this zone do not need a temporary vehicle import permit, which saves you a bureaucratic headache and a deposit requirement. Cross that boundary and you need a TIP, which is why most RVers stick to the coastal corridor.

Border crossings and access matter. The Mariposa crossing on Highway 189 (Exit 4 from I-19) near Nogales is much easier for large RVs than the downtown Nogales crossing. The Lukeville crossing from Arizona on Highway 85 drops you right into the route to Puerto Peñasco. Cross early in the morning to maximise daylight driving time because the golden rule in Mexico is never drive at night. Mexican auto insurance is mandatory; US and Canadian policies are not valid once you cross. Fill fuel at every Pemex you see on the way south. The listings below cover the dump stations across the state with notes on the free zone boundary.

Of the several dump stations we track in Sonora, some (a portion%) is free while a portion% charge a fee. The paid-heavy ratio is standard for Mexican RV travel because the network is built around private RV parks rather than municipal facilities. Site fees at coastal RV parks in Puerto Peñasco, San Carlos, and Kino Bay typically run 15 to 35 USD per night, with dumping included. Mexican auto insurance adds around 22 USD per day for short-term coverage, and you need it by law. Propane is cheaper than in the US, typically half the price, and mobile propane vendors visit coastal RV parks on a regular schedule. Fuel is roughly comparable to US prices.
