Ruby, Alaska (PARY / RBY). Either direction. Picture a ski jump, then at the other end of the jump, have the terrain continue at the same rate as the other side. That's Ruby. We tend to take off downhill and land uphill. On landing you clear the top of the hill and drop the power about to idle to catch up to the terrain and the runway (or many times to idle, especially with a tail wind, this with a B1900). On takeoff you rotate just as you get to the bottom of the dowhill portion and get to start outclimbing the terrain.
Close secong is Nulato, Alaska. (PANU / NUL). Sloped runway. Lower end has a cliff, upper end has a good sized hill. Just a really cool sight picture, winds can be tricky (get some good sinkers with the cliff sometimes), but mainly just the picture when you are looking down the runway coming in for landing and this hill that now looks like a mountain is directly at the other end. The cliff drops directly to the Yukon River.
Both of those top two are gravel runways as well. It gets more fun in winter when they are icy.
The Knik 6 departure in Anchorage coming off of the 7s is cool. Puts you over downtown Anchorage and overtop Elmendorf AFB. You're also pointed at some rather large mountains on takeoff. The Highway Visual to 25s is kind of nice, but not as exciting once you've done it a dozen times or so.
The LDA approaches into Juneau and some others look really cool, but we don't operate down there on a scheduled basis so I haven't done those myself.
And the NDB-DME approaches are neat to do just because they are so rare these days.
