It's not my kind of sports (I don't really know if it may be classified as sport) but the lovers of naturism may enjoy a spot unusually close to the city centre.
The north side of the cape is wild, and naked people use it without any kind of problems, except the difficulty to enter the water.
Directions: along the coast
I was alerted that driving and parking in Piran was restricted, and that I should leave the car in the modern park, built a few hundred meters from city centre, at the end of the bathing area.
Seeming a bit far, I risked to drive as close as possible, and, as a matter of fact, I could park closer to the historic center.
Leaving the city I verified that the mentioned parking lot is not a bad solution, because they have a free shuttle to town.
Next time, I will already know!
