Go up the Formentor Road to the Mirador point where there are lots of parking spaces on the left, and a few on the right. Its usually very busy. There is a turning on the right where the parking spots are. Drive past the cars up the narrow road. You can see the tower on the top of the hill. Its not very far but quite hairy. The road winds up for a small while (sorry - not very good with distance! ? mile or so ?) Right near the top is a small turnaround area where a few cars can park, or also on the road before you reach the area. That was the bit that did for me, there are hardly any barriers, and you have to keep the car in tight! You then walk further up the road and round the corner to the tower. A few cars drove the extra distance, and you can turn around in a very tight space at the top, but the road is narrow with no barrier whatsoever and a VERY long drop! I certainly wouldn't attempt it. When you gvet up there, the view is fantastic.
