If you walk for a certain distance from the dolphin nose through a narrow path, you will reach echo rock.
This rock provide you the 360 degree view of the beautiful mountains. But this is so dangerous and extremely risky. I could not climb on top of the rock as it was extremely scary for me. If you guys are going for it, please be very careful and cautious.
Once you reach the starting point of the trek, there is a n Altafs cafe. It offers wonderful view of the different layers of these mountains. We could not watch the sunrise here. If it's possible, you guys go for it. And you can have some amazing food here as you will be exhausted after the trek.
How to reach there
We were travelling from Bangalore. Hence we travelled by train until kodai road, from there we hired a cab until kodaikanal. It costed around 300 per person from there. It takes around 3 hours to reach kodaikanal from here. It's a ghat section, please carry some tablets if you have motion sickness. You can travel from dindigul as well. There are buses also from kodai road/dindigul as the villagers said and it would be cheaper. But we went by cab while going. However while returning from kodaikanal to kodai road, we came by bus. There are buses at certain timings. Please check with the localites and they will provide you with all the information.
Regarding the stay, we stayed at highland Paradise. The hotel was gud, it offered beautiful views. But the only thing is it's quite far from the kodaikanal bus stand. So you can choose hotel accordingly which is near to the city. Else you have to pay extra for the cab. We visited in the month of January and it was very cold. So please make proper arrangements.
