Destinations:

Guadalajara, Jalisco (Approx. 1.5 hrs from Jalos)

Leon, Guanajuato (Approx. 1 hr from Jalos)

Aguascalientes, Aguascalientes (Approx. 45 mins from Jalos)

We'd recommend flights that land in Mexico during the day for ease of transportation to Jalos and safety. As well as traveling in groups, it will make it easier to arrange the transportation from the airport to Jalos (and make it fun).
