Umiam Lake is famous for its lovely little Boathouse by a lake island, the Lumpongden Island. Visitors have to book the Boat House in advance. Only one group of people (6 people maximum) can stay at the Boat House at a time, so the ones needing peace and privacy away from the crowds frequently book this place.
