Buenos Aires – Arivaca

Development Route

Given this route is still a development route, this slide deck represents most of the route, but not all of it.

This route is an extension of the 5 Star Buenos Aires route. At mile 22, the route turns right towards Tres Bellotas Ranch / Arivaca on FS 216 instead of continuing straight as on the original route.. At the town of Arivaca, mile 28, you can refuel and get water. The route then heads west on an undulating, Arizona paved road with little traffic. Many will find this section of road riding enjoyable and a nice break from the gravel. We drove this portion, we did not ride it.

At ~ mile 36.5 the route heads south on gravel reconnecting with the original route at ~ mile 41. We have not ridden nor investigated this section with “boots on the ground”. Thus, the designation of the route as a Development Route.

We believe, that 40 mm tires will work well on the route.

The route comes very close to the border with Mexico and parts of the route are actively patrolled by Border Patrol. When we come across them for the first time in the day, we stop and ask if “there’s anything we should be aware of” and we also give them our route for the day. We saw no Border Patrol on our ride.

The Dirty Freehub Team has not ridden this route, thus the Development Route designation. If you do the route, please give back to the gravel community by (a) leaving us a comment below or, (b) better yet, by completing the Share Your Route form.
