great map. I've visited most of them, Martin's Bay is a really easy one (top of the map - there are 2 strips close to each other), Lake Alabaster and Hollyford Valley are a bit more tricky, but nothing compared to Quintin. Another really good one is the Siberia valley one which is further North (ie west of Lake Wanaka) - don't know the coords, but should be relatively easy to be found using google or google maps.
Ian - using heli's is cheating

Does help in Quintin though. I certainly would recommend the Beaver or Maule, Porter may be even better!
Hmm, time I took my Do27 for a ride - and maybe write up some tours. Or something with the Fletcher...
Cheers,
