From Istanbul
you can either take D100 or O-4/E80 motorway/toll-road east to Izmit, then head west there along the southern shore of the Gulf of Ä°zmit to Yalova, or take a ferry -which can accommodate cars- to Yalova. Once in Yalova, take D575/E881 highway south to Bursa. After about 30-40 km away from Yalova, you'll arrive in Orhangazi. At Orhangazi, you'll notice the junction of the secondary road lying on the northern shore of Lake Ä°znik there are Ä°znik/Nicaea signs. From that junction, Ä°znik is about a 30-40 min drive away.

If you choose not to take a ferry to Yalova, you also have the option of taking the mountainous road which forks from the main highway about 5 km west of Karamürsel. This road is shorter than the above route, but curvier.

From Bursa
Take D575/E881 highway north to Yalova. Somewhere between Gemlik and Orhangazi, you'll come across a junction with traffic lights. On that junction, you'll notice Ä°znik/Nicaea signs. That road will take you to Ä°znik along the southern shore of the lake in about 30-40 minutes.
