one can use other start point to reach the golden beach (like the paved road of rumeli feneri)

Rumeli Kavagi - Rumeli Feneri - optional Garipce (by Dogus CICEK) After leaving Rumeli Kavagi, a paved forest route will take the riders to the point where the Bosphorus and the Black Sea joins. There is a place (cafe/restaurant) to eat/drink and re-stock supplies at Rumeli Feneri. The Fener is a historic lighthouse which has a small exhibit about it's past and the view from the seaside is beautiful. Riders can also ride west from the Rumeli Feneri to reach a seaside hotel called Golden Beach consisting of several bungalows of mid-high luxury (beware of the high prices though). Riders can visit "Garipce" on the way back or before Rumeli Feneri, which is several miles south of Rumeli Feneri. Beware that the road turning into Garipce from the forest road you came may be gravel or dirt so road bike riders better be cautious. Garipce is a fishing village with a restaurant. And of course the best place to visit while in Garipce is the ruins of an old castle and redoubt which is located just at the north-side of the village. (You have to go one floor underground to walk in the redoubt - beware that the redoubt is uniluminated so better go in during daytime) Garipce is said to be razed to the gorund in the years to come because of the plans to build a third bridge across the Bosphorus so it is a great time to see the place before is destroyed.
