Most of the open country in Eravikulum National Park was closed to hiking as of last year. There are so many medicinal plants in these high range meadows, and people were picking them clean. So now there is just this one section you can walk in, and they want you to stay right on the road, as the sign says. The second part of the sign is in Malayalam, the local language here in the state Kerala.
As you can see in the second photo, even the birds obey the signs! Not sure if it read the sign in English or Malayalam. (Although it looks like a small meadowlark, the bird is a Nilgiri pipit, a species found only around here).
