The approach into HNL sounds like it would be gorgeous<(spelling?). Went there many years ago as a pax and was too drunk on free champagne to notice anything out the window.
There is a grass strip here in Ore at a airport called the Flying M Ranch and it is in a box canyon, very tight and unforgiving with a horse corale fence at the end of the rwy so make it right or crunch. It has a short strip, so on t/o you also have to clear the trees. But, it is beautiful to fly into or out of. Try and find it on MSflight sim, if your into it, and give it a go. Do it during the fall for those lovely colors on the mountain sides.
