My wife and I have done a number of running tours - but this was by far the best. We signed up for the personalized tour (2 hours), and within a few hours Yovo emailed us and asked us which tour we would like.
He showed up the next morning at our hotel lobby to pick us up at 6:30 am and we were off to Diamond Head.
We parked and started the run. He was extremely polite, provided a lot of history, and even provided us with drinks and rain coats (it didn't end up raining that day).
He led us up the crater, with frequent stops for some historic tidbits and some water breaks.
We reached the top and he took us to a nice spot where we sat and had a bit of a picnic. He went ahead and cut us up some fruit, granola bars etc. It was really an amazing experience. He also took photos of us throughout the tour so that we could commemorate the event.
I suggest doing this tour and if possible, as for Yovo!
