As spectacular as it can get. Exceptional views of Sperlonga and the sea. The nice thing: definitely an easy climb averaging not more than 5-7% and the descent is wonderful. Best time is early morning or sunset.

Panoramic point from where you can see the islands of Zannone, Ponza and Palmarola. The square in front is on a dirt road. To get there you have to climb up to San Felice Circeo, about 1.5 km with gradients of over 12% and the other that takes you back to the town (the lighthouse is on a dead-end road) of 1.5 km of pedaling, with the last 3/400 meters at 10/11%.
