One of our favourite hiking trails we have ever done! The hike to the lake & back is 22KM which can be done as a day hike but we decided not to go all the way to the lake after speaking to some people who camped there overnight. They said its a lot of up and down mountains to get there and will easily take 8+ hours to do. Instead we opted to go for the Mount Monolith Viewpoint which can be seen on the map at the start of the hike. That is 6KM round trip and took us 6 hrs with stopping for lunch. The views are just incredible.
