Looking for a good challenge in MSFS? Here's one: New Zealand. Use the Cessna 208. Start at Queenstown NZQN. Fly Northwest to,Martin's Bay Aerodrome KZMJ, and make a landing. Beware the high terrain enroute, and be ready for the white-knuckle adventure awaiting you and your passengers when you arrive! I'll let you figure out your own approach. It might not seem possible, but I assure you it CAN be done. You may find, like I have, that New Zealand offers both grand scenery and an endless array of challenges.

I watch Kiwi Mace's flights on YT and he does go to some amazing places in NZ.
