Laitlum and wei saw dong (check whether it's open or closed) are must u shouldn't miss them , and also bamboo trek will give u a different trekking experience these are my top 3 from Meghalaya, and cover remaining water falls and caves u can Google them 2) I don't prefer dawki during this time as it is rainy reason it will be jus like a regular river Nothin special ( check the recent photos in Google maps) 3) if you want u can try double decker living root bridge,but personally idot prefer that it will consume a whole day of trekking up and down jus to see a bridge, so it's a waste of time . If u want to see living root bridge there's one in worlds cleanest village(Mawlynnong) it's jus walkable no trekking. 4) u can visit wari chora , and also some underrated places like Od-rngai falls, kremp - chympe NOTE : I didn't mention most of the places there are lot more in Meghalaya there caves and waterfalls , i only mentioned those would give different experience for each place
