Santa Cruz de la Sierra is a sleepy village 15 minutes’ drive from Trujillo, set against a mountain towering above the landscape. That mountain almost asks you to be climbed. There are several (weakly marked) routes, but even if you lose track to the top, it is a nice slope to walk on, with unexpected pools with frogs and water conduits from the time of the Romans. The cows that sometimes block your way, will fill the valley with the sound of their bells, until long after they have decided to let you pass. The views (to Trujillo) are beautiful.
Upon return, the village offers two restaurants for lunch or dinner. More than an hour to het to the top and more than an hour before the return trip.
