İnönü Plateau, located at an altitude of 1050-1130 meters at the foothills of the Samanlı Mountains in Kocaeli's Başiskele district, is a free natural area suitable for camping and picnicking, with vast meadows surrounded by pine and fir forests.
İnönü Plateau is located within the borders of the Başiskele district, affiliated with the Kocaeli province, close to the Sakarya-Kocaeli border. Stretching approximately 1050-1130 meters above sea level, the plateau is surrounded by dense forests of pine, fir, and oak trees. This wide plain, about 500 meters wide and several kilometers long, has become a popular spot for visitors from Istanbul and Kocaeli to breathe fresh air on weekends.
A small cave is located on the western side of the plateau; the clouds drifting above you with the wind make this place visually very impressive. Approximately 12 kilometers from Tepecik village, the plateau offers a suitable natural area for those who want to camp, picnic, and explore hiking routes. It continues to be one of Kocaeli's most accessible plateaus for those looking to escape the city crowds.

Guide's Note
İnönü Plateau, with its pine forest surroundings, clean air, and cool climate, is a natural area preferred by those who want to camp or escape the city noise. Visitors particularly appreciate the clean water sources, the cool air that necessitates campfires even in mid-summer nights, and the relatively uncrowded environment. Morning temperatures are reported to drop to 8 degrees Celsius even in July; therefore, a sleeping bag and warm clothes are essential.
The plateau is completely natural; there is no entrance fee, facilities, market, mosque, or electricity. Clean water is available. The likelihood of encountering crowds on weekdays is low. Campfires and barbecues are allowed; wood can be found in the forest. Visitors particularly emphasize preferring previously used fire pits and taking their trash with them.
Some points to consider regarding the road and accommodation are frequently repeated in comments:
- Road condition: The Yuvacık-Tepecik route is quite rough and potholed; some visitors state that their vehicles got stuck on this road. The Çilekli or Sultaniye-Hüseyinli route is suggested as a better alternative. In winter conditions, coming without a 4x4 vehicle is risky.
- No phone signal: GSM signal is absent or very weak throughout the area; come prepared accordingly.
- Night gunshots and loud music: More than one visitor has expressed discomfort with gunshots and loud music continuing late into the night.
- WC: There are either no toilets on the plateau or they are unusable; trash containers and toilets are available in nearby villages (e.g., Çilekli).
- Trash problem: Many visitors draw attention to the trash left in the area; you are expected to take your trash with you.
Best Time to Visit
The most suitable period to visit İnönü Plateau is the summer months, extending from early June to late September. During this period, the plateau meadows take on a lush green appearance, and the weather is cool and refreshing. While scorching heat is experienced in the city, temperatures around 20-22°C on the plateau provide great relief.
In October, the forests turn yellow and orange, gaining a special charm for photography enthusiasts. As snowfall and road closures can occur in winter, it is necessary to check road conditions before going during this season.
How to Get There?
The most practical way to reach İnönü Plateau is by private vehicle. Located approximately 30-35 km from İzmit city center, the plateau can be reached by taking the D-130 highway to Başiskele district, and then proceeding in the direction of Tepecik village. Since road signs may be insufficient, it is recommended to search for "İnönü Yaylası, Başiskele" on your navigation app.
Direct access by public transport is not possible. For those coming from Istanbul, after crossing to Kocaeli via the TEM Highway, follow the Başiskele direction. As you approach the plateau, the roads narrow and become more winding; therefore, preferring a high-clearance vehicle will make the journey easier.
What to Eat, Where to Eat?
The plateau itself does not have a permanent restaurant or cafe infrastructure. The vast majority of visitors bring their own food for a picnic or set up a barbecue. Eating outdoors in the plateau environment becomes one of the most enjoyable parts of the visit.
For those who want to go prepared, there are markets and small restaurants in Başiskele district center or surrounding villages where you can meet basic needs. It is recommended to complete your shopping at these points before heading up to the plateau.
Photography Spots
İnönü Plateau offers several different shooting opportunities for photography enthusiasts. Panoramic shots taken in the wide grassy areas of the plateau create a strong contrast with the rising pine forests in the background. Layers of fog and clouds covering the plateau in the morning hours create dramatic landscapes.
The small cave on the western slope also stands out as an interesting shooting spot. In October, when the forests change color in autumn, it is possible to capture plateau views framed by yellow-orange foliage. The golden hour light before sunset adds a soft tone to the meadows and treetops.
How Many Days to Allocate?
For those planning only nature walks and picnics, half a day to a full day is sufficient. You can start early in the morning, arrive at the plateau, have lunch in nature, and return by evening.
For those who want to stay overnight by camping, 1-2 nights would be an ideal duration. This way, you can experience the morning fog of the plateau, the night starry sky, and its atmosphere at different times. Those who want to explore the forest roads and nature routes in the vicinity should also plan at least one night's stay.
Things to Pay Attention To
Since there are no permanent facilities on the plateau, it is important to carry drinking water, food, and first aid supplies with you. As cellular signal may be weak, it is recommended to download and save important numbers and map data in advance.
When lighting a campfire, extreme caution should be exercised against the risk of forest fires; the fire should never be left unattended. Since there is no trash collection service on the plateau, it is of great importance for visitors to take their trash back with them to preserve the natural beauty of the area. In winter months, it is necessary to follow the road condition announcements of Kocaeli Metropolitan Municipality before setting off.
Route Suggestion
For those departing from Istanbul or İzmit, the following route can be suggested: Complete your shopping in Başiskele district center, then follow the Tepecik village route to ascend to the plateau. Upon arrival at the plateau, first explore the wide grassy area on foot, then make a short climb to the cave on the western slope.
After having a picnic lunch on the plateau, you can explore the surrounding nature by following one of the forest trails. Those who want to extend their day can try hiking routes that extend to points near the Sakarya border. Stopping for dinner in Başiskele or İzmit city center on the way back would be a nice conclusion.
