The site where the Colossus once stood is a momentary stop, but Rhodes offers plenty of other history. Ascend the Acropolis of Rhode, which rises above the port. Or stroll through the scenic Old Town, where you can climb the clock tower for a bird's-eye view of the city.
Take the 20-minute drive to Phileremos. It's a moderately difficult hike to scale the hill here. At the summit, you'll encounter a priceless panorama and a peaceful monastery lined with cypress trees.
