We took the gondola to the highest point and it was so beautiful. The hike is not that great, but the views are gorgeous. Make sure you hike to all sides. Each one has unique views. From one side we could see all the lakes. From another we had the views of the city.
It was the first week of August and it was windy and kind of cold. I suggest you to take a wind breaker or hood. even on a hot summer. Not sure if it is cold all the time.
We saw many mountain bikers also taking the gondola. It must be marvelous going down these mountains.
The lunch there was just OK.
Look for discounted tickets from the hotel you stay.
