Blow hill is to be visited during monsoons. One of the best places in Kerala where you can actually witness horizontal rain and winds so strong that if you jump you land few feet back. If you are daring enough you can ride your motorcycle to almost 70% up ,more of a hill cclimb challenge to be frank. But getting your motorcycles downhill is a challenge, moss rocks and loose mud doesn't make the affair smooth. Getting on top is itself a challenge worth contemplating.
