Silent Valley is a frequent target of Maoist-extremists. While the situation is more stable than it was in 2014 and 2015, Maoist groups are still active in the area and have stolen property and disrupted government operations within the park.
Silent Valley National Park is at Mukkalil, 20 km from Mannarkkad town in Palakkad District, Malabar, Kerala, India.
The park is named Indira Gandhi National Park, and Silent Valley is the name of the place, but it is also called Silent Valley National Park. It is a wonderful place to visit for tourists.
Silent Valley is considered one of the most ecologically diverse areas on the planet.
In the 1950s, the Kerala State Electricity Board wanted to build a dam across the Kunti river, which flowed in the deep forest. Nationwide protests in India by environmentalists and mass publicity by the media led the then prime minister, Indira Gandhi to order the state government to abolish the hydroelectric project. The area was declared a national park.
Tropical evergreen forest, the highest peak is 2,383 m above sea level. Huge trees, thick undergrowth. Heavy rains during the monsoons. Shola grasslands higher up.
The tourists are taken 22 km into the buffer zone and only 1 km inside the core forest. You can see the board 'Silent Valley National Park' at the entrance of the buffer zone. You will see the same board again after 22 km at the entrance of the core forest. The ride back is in the same route.
The park is inhabited by 16 species of birds, 34 species of mammals, 730 species of insects, 128 species of butterflies, and a 1,000 species of flowering plants. The mammals in the park include the threatened lion-tailed macaque, tiger, panther, leopard cat, civet, mongoose, otter, sloth bear, flying squirrel, Indian pangolin, porcupine, wild boar, deer, elephant, giant squirrel, Nilgiri tahr, Peshwa's bat and the hairy-winged bat.
Humid during the rains (June, July, August), otherwise generally hot and tropical.
The nearest railway station is Palghat Junction. From Palakkad, go to Mannarkkad, and from there to Mukkali. KSRTC buses are available every half an hour. If you are planning to stay at Mukkali, reserve rooms in advance at the Forest department resthouse. Or else you can stay at Mannarkkad or Agali Hills and hire a jeep to reach Mukkali by 8AM. Mukkali is about 60 km from Palakkad, with Mannarkkad en route. The visit to the Valley and Kunti river will take only a day, and you can return to Palakkad the same evening.
Another nearby railway station is Coimbatore Junction. From Coimbatore, take the road to Anakatty (around 30 km) and from there to Agali Hills (15 km) and then to Mukkali (20 km). The total distance via the Coimbatore route is only around 65 km. Its almost a straight road drive from Coimbatore to Mukkali. The scenic roadway keeps one captivated all through.
Entry into the valley is allowed only from 8AM to 1PM. The Forest Department deliberately does not allow going to the valley early in the morning to minimize disturbance to the animals. Every vehicle will have a free guide. The vehicle will move slowly all the 23 km and they will stop a few times on the way for five minute photo sessions. Animal sightings are quite rare and the view from the watch tower at the end is quite spectacular. Only 12 adults are allowed into the watch tower at a time. But a lot of Indians ignore this warning and get into it creating a dangerous situation to the fragile structure. This point is 1,050 meters above sea level. You can trek down to Kunthi river and see the hanging bridge. One hour is allowed in this place.
Apart from that, the trip can disappoint you if you are not a tree bum. Thick vegetation of the silent valley evergreen forest is the only attraction. The road is unpaved and the terrain very bumpy. They take a total of five hours for the trip. If you forget to take drinking water, you are lucky, very tasty mineral water is available free behind the parking space at the watch tower. If you are carrying a bottle of commercial 'mineral water', you can empty the bottle and fill it to the brim with this pristine water.
The signboards of the government on the main road outside can mislead you because distance to the park is shown including the 22 km inside the park. So every time you see 'Silent Valley National Park', you have to reduce 22 km. Similarly the distance to 'Attappadi' means that so many km more to finish Attappadi region and not so many km to reach Attappadi. You cannot reach Attappadi because it is not a place but a region. The entire stretch between Mukkali and Agali is called 'Attappadi' and Agali town is also sometimes referred to as Attappadi.
Enjoy the thick jungle, see the birds, you are lucky if you see the big mammals (on the short trek). Mostly you will see the Malabar Giant Squirrel, black langurs and of course many kinds of birds. Trek down to the Kunti river. There is also a watch tower overlooking the jungle. The back of the Inspection Bungalow at Mukkali is a great place for bird watching.
Take a bath in the Bhawani River at Mukkali.
There is one Sairandri restaurant at tree top resort, Chindakki near silent valley where you will get delicious food. And you have one small restaurant at Mukkali junction which is extremely crowded. For better food options, you have to get down to Mannarkkad. One small restaurant is conveniently located in front of the Park office, but they have too many customers and too little staff, and you may not get any attention for a while.
The forest department has a guest house and dormitory at Mukkali. Rooms have to be booked in advance. Rooms are decent, without expecting anything more than what can be expected in remote outskirts. If your focus is nature, then it shouldn't matter. Ensure you are prepared for power cuts, which are very frequent. The forest guest house is at a good, peaceful place, with the Bhavani River just flowing behind the guest house.
More lodges are available at Agali Hills, 20 km.
Tourists are not allowed to stay overnight at the valley; they have to return to Mukkali by evening. You can ask permission from the forest department office if you wish to camp in Mukkali. Or you can camp in Agali Hills or Mannarkkad.
