Hi Raga,

I have never been to Sequoia NP before and know nothing about the terrain. However, I did find a couple of links that I thought were helpful...this one in particular:

http://www.americansouthwest.net/california/sequoia/national_park.html

The second link talks about Kings County Park - apparantly adjacent to Sequoia.

I hope this helps. I wish that I could be of better service to you.

Sincerely
James
