If you're looking for an invigorating workout outside, this is the place to do it. There are various trails you can take and different levels of intensity. The walk here from the Phoenician is a bit of a hike but just be sure to bring water.
We didn't reach the top but we had quite a nice hike and it's even more interesting trying to get down (especially if you're short and realize how tall the rocks are the you climbed up to begin with).
Beware of rattlesnakes... I'm about 90% sure I heard one in a bush under a rock and totally freaked. But the hike up is totally worth it for the beautiful pictures. Give it a whirl. And go in the morning before it's too warm! :)
