Yes

This place is famous for its Rock climbing,and trekking. Water fall is there but not a big one... Nobody baths here, people just enjoy trekking on the rocks.

After Monsoon wud be the best for Kerala Based Water outlets. Summers are very hot, humid and sultry.

JayantSathe has answered your question above - check with the park authorities regarding current water levels.

As far I remember,it opens till 5 or 5 30,try to be there by 3 pm. If you don't plan to take bath, the time is more than sufficient,

This is located near Banasura Sagar Dam (~2.5 kms away). First two stages are OK/moderate and last stage is little complex to trek. There are ropes installed using which people can climb up the rocks. Note: Do not expect falls in full swing (atleast the case in Dec16).

yes you can but not at the top.after walking one km from the gate you can.
