Oscar winner Jared Leto stunned guests at the Resort at Pedregal in Cabo San Lucas, Mexico earlier this week (begs09Nov15) when he opted to scale a wall of the hotel.

A source tells Page Six, the adventurous Dallas Buyers Club star was admiring a rock formation adorning the entrance when he decided it was worth climbing.

"A few minutes later, he was gone," the scource says. "Everyone stopped to watch him scale the rock wall. It was so unexpected. He made it to the top in no time."

Leto was in town for the Los Cabos International Film Festival, where he presented an award to Dallas Buyers Club director Jean-Marc Vallee.
