Ponmudi is, indeed, one of the most beautiful hill station in kerala, I was taken aback by its scenic beauty and serenity of the place . unlike other hill station that are either over crowded with people, ponmudi is calm and peaceful, there are not many shops and hotels
if I had to put in one line, I would say ponmudi is not a place to tourists: its a place for travelers, if u happen to visit ponmudi, make sure you go all the way to cliff, and take some time around to gaze the beautiful open farms .there are no points in the hill station, its just the experience thats amazing.
you could literally feel and watch the clouds floating besides you, the air is amazingly cool and if you happen to go around October-December, you can also feel the mild drizzle.
make sure u wear shoes with rubber sole, or the ones that have solid grip .Also, if you are too tightly wound, take an umbrella(i advice against it though), have enough water, since the uphill climb can get tiring .
you can hire a cab or if you are in a group, you can get a local bus from trivandrum station, it takes around 2 to 2.5 hours to reach ponmudi depending on the weather and traffic.
