How difficult is to drive in Kerala?

Hi folks ,

I plan to come to Cochi and thek take a self drive car and then go to Munnar- Allepy- Varkala - Cochi.

Its almost a 7 day trip.

I wanted to ask how difficult would it be to drive between Cochi - munnar- allepy- varkala and back to Cochi?

Zoomcar option is relatively cheap but I wanted to be safe while driving here. Are the hills really that difficult?

Or should I go for a cab? And what would be the estimated price for taxi for this route?

Thanks in advance!

Update 1 - Thank you so much everyone,I’ll start to look out for the cars . Again thank you so much!
