After spending time in Varkala we went to Kovlam beach which is not far from Varkala
You can take government buses from there Kerala is full of greenery so you will see more..
We haveStayed there in Kovlam hotel cost was 700 per person for beach hotel there are so many hotels in Kovlam beach it depends on your budget
Water sport is also there so you can do that activity also.in my experience have a chilled beer in evening and enjoy the sunset and if you are sober then anything chilled will work
And food you can try Kerala thali that will be delicious
And others are like idli vada,dosa depends on your taste
