"Beautiful place to visit after lake Akan. A must visit place to feel like heavenly atmosphere. Cool breeze and beautiful views and nice pictures to be taken. Enjoyed this place but the driving was little winding road so be careful and drive within limits of the speed mentioned. Sharp turns are inclined."
Ravish M
"If you only have limited time around Lake Mashu, head to Observatory 1, where there's a bird's eye view from a high vantage point for the entire lake. Grab an ice cream or pork rice at the cafe and pick up some souvenirs as well."

Understanding Lake Mashu's Mystique
