K2S night trek is a difficult trek and it will test your patience and stamina. As the name suggests it’s a night trek and you have to walk around 15 km to reach the Sinhagad. The Katraj to Sinhagad Night trek starts from the Old Katraj Tunnel. You need to pass 15 small and big hills. The last few hills are very challenging. The trek starts at evening and you will reach the Sinhagad in the early morning. I will suggest you go with the team or with your friends. There are many K2S night trek organizers in the city. The K2S path is confusing even for the experienced trekkers and you will not get a proper network in the area. Although it is a difficult trek, I still recommend you to go. The views of an entire city from the top of the hills are marvellous. It’s a once in lifetime experience.
