Thanks hubbs, that is very helpful actually. Especially the web page re charts. At the minute not sure the routing, however have done a bit of flying in high terrain. Its more the weather that would be my concern flying around those mountains!
Current plan would be to do the round trip in approx 6 / 7 days. Would be 2, possibly 3 of us sharing the flying. Once we look at the charts and routes, will have more realistic figure of how long we would need to do it. and think it would be more flying than seeing the sites, however would like to get some sites in too whilst over there. But ultimately all depends on cost really.
Ego, thanks for video link, never seen that - looks like they had a great time, although they seemed to have more time we will have unfortunately
Many thanks
