Changes

Get the 629 bus west. The bus travels along Avenida Vallarta and over the ring road junction to the highway Guadalajara-Tepic. Get off when you see the "Guadalajara Technology Park" complex on your right. Walk for 5-10 mins more in the same direction and you will find a reasonably sized petrol station with shops and restaurants. If you walk back on yourself you will find another petrol station with an OXXO but it is smaller than the one up ahead and you will find it is where many people stop just on their way to the Technology Park.
