This large heart-shaped "tepui" (flat-topped jungle mesa) is most famous as the site of Angel Falls, the highest waterfall in the word. The 900-meter high cascade plunges over a cliff on the western side of the great canyon that almost bisects the tepui.
There is a tourist route that attains the top of the mesa via a weakness in the cliff walls on the south, conveniently near the highest point. Trekking companies offer week-long jungle treks to this remote and alluring location, but the highest point marked on some tourist maps does not match the highest location from SRTM (Shuttle Radar) data.
Note that the Google Terrain map's elevation contours are a couple hundred meters low, based on other reliable sources.
