How to avoid snakes in Sri Lanka?
In the context of Sri Lanka, being an integral part of its natural environments, the presence of snakes is very rarely experienced in general and is more rarely experienced in natural or other sites visited by tourists. Most snakes are very often seen in forests and rural areas.
It would be good to see that you do not push your way through bushy places or places after dark with poor lighting. It would be good to wear closed shoes and long trousers, especially when one is walking through the wild or rugged terrains, watching one's step.
If you decide to stay in or around a forest, bear in mind to keep all doors & windows securely locked; and whatever you do, never leave food outside in the open. Follow these simple steps, and the probability of a brush with these snakes is by all means minimal, thereby giving you a comfortable chance to enjoy your holiday in peace.
