I stumbled upon this park during an impromptu blizzard in Lyon, and even the freezing cold weather didn't stop me from loving it. You can rent bikes (one of the great things about Lyon - their bike rental system is fantastic) and take a ride around the lake. There is a beautiful botanical garden and even a small zoo at the eastern end of the park (though, like most zoos, it's slightly depressing). If you're looking for somewhere to jog or get a nice walk in, this is the perfect place !
