Buenos Aires

5 Star Route

Remote, rugged natural beauty. Emptiness. Big views. That’s the Buenos Aires National Wildlife Refuge which has 200+ miles of dirt roads, which just screams, “awesome gravel route.” We have to admit, we have long debates on favorite routes. But when we rode this one, there was one major conclusion: this is our favorite ride in the Tucson area. 

You will meander across the grasslands of Buenos Aires National Wildlife Refuge, roll through washes and past old sycamore trees, pass within a klick the Mexican border, grunt up one steep hill that provides just enough elevation for a grand view of the whole area and swing back to the start with Baboquivari Peak off in the distance, just calling you to go further. **Click to Read More

Moderate. There are several short, rocky sections and several short, steep pitches in excess of 10%.

When we like to ride this …

Fall to spring when the skies are clear and the temps are moderate. We would avoid this route in summer as it is very exposed to the sun and could be quite sandy. Wind could also make this route brutal. And … if it has recently rained, give it several days to let the washes run shallower or dry.
