I was recently doing some practice flights around Switzerland, and found this freeware ORBX Airport pack LSGK (if you have Global Base or LC Europe) https://orbxdirect.com/product/lsgk and wow I've never had this much fun trying to land a small aircraft! There are some ways into the strip but it's unconventional and you really need to be aware of your surrounds at all times!
Do you have a favorite "difficult" airport? If so, do tell where!
