I have been to Wayanad 3 times and every time enjoyed to the fullest.
The drive from bangalore to Wayanad is fun and full of adventure as it passes through the Wayanad sanctuary. You can find lot of elephants, deers, peacocks and many more on the way.
Food is somewhat okay not that great in the hotels on the highway. The best attractions are siji pura waterfall and kuruva islands but in kuruva islands , most of the islands are closed. The eddekkal cave is also good attraction for one time visit.
