There aren't too many interesting things to do in Caracas, especially for tourists that don't know their way around and could get into trouble. The teleferico is worth the visit as the views are pretty spectacular. There are a few restaurants up there...nothing to write hoe about, but it is good for an afternoon. Bring a sweater, it gets cool up there 3000 meters above sea level. Don't carry too much cash and no jewelry at all. All of Caracas is dangerous and people have been held up.
