It's very hard to miss the landing place. It's big enough.
Just go landing, where it's intended.
Be careful when you land in Talloires. If you miss the landing site, you land on the land of a very disturbed, agressive farmer. When this happened to me, the madman drove with his tractor over my pent and pulled it for 50 meters over the meadows. Other villagers will not help you. Be aware and try to avoid these guys.
