Welcome to Lake Geneva!
I think kitesurfing has existed on the Vengeron spot for more than 20 years. Back in the days of the first Wipika 2-line kites around 1998-1999, you could already see the first kiters from Team Force 5, with Yvan leading the way, doing their first attempts and crossing the small lake.
The Vengeron spot is very nice, you rig your kite on the grass, the wind blows full force on the launch area, if it wasn't for that damn water entry, the spot would be perfect! But once on the water, the slightly tricky passage through the rocks is quickly forgotten! One thing to note is that the small lake is forbidden to kites from the (virtual) line Vengeron-Square Tower. So once on the water, don't forget to quickly head upwind.
For after your session or if you need advice, the Force 5 refreshment stand on the spot is a must-visit to discuss everything and recharge your energy. If you have any kite questions, ask for Yvan.
