Benito Juarez National Park protects pine and oak slopes above Oaxaca, giving the city a wild edge that is easy to miss from the markets and colonial streets below. It is a good choice when you want fresh air, altitude, and a different view of the valley.
The park works best for walkers who are comfortable arranging transport and checking current access locally. Treat it as a nature outing rather than a polished urban attraction, and carry water; the climb and sun can be tougher than the distance suggests.
