Si vous parlez du temple de la colline aux singes à Hua Hin, pour y aller prendre le Green bus jusqu'au terminus et après 15 minutes à pied en suivent la route qui passe par le port de pêche.

No entrance fee and definitely worth the trip. Take heed of other advice here by all means, but don't let it put you off going - go to the top temple, great views. Also go down to the Chinese temple, it is very peaceful. Buy food for the monkeys, it is about 50 baht a bucket, but leave handbags etc. in the car.

OK, I am not sure what you mean by "Monkey Island", some people call it Monkey Mountain, but if you go up the steep, steep winding road all the way to the top to where the steps to the Temple on the very top of the mountain is located, there is a maybe 30 car/pick-up truck parking lot surrounded by small food and gift shops. There is additional parking up a dirt road at the back of the parking lot that goes to a plateau where you can stand on the cliffs looking out over the water. There is also a shrine to a famous monk on this plateau and when I was there, a number of discarded Buddha statures - probably waiting until they are installed in a future shrine. So yes, there is parking.
