This was a very nice walk with great views from the top - as others suggested give yourself extra time at the top, it's nice to hang out look around at some of the bunkers etc. Be sure you go to the very top - not just the viewing area. It would have been nice to go down and see the lighthouse closer up, but you can't. Definately take water - it gets really warm at certain spots where there is no breeze on the walk.
