A moderate walk in the Grampians to the top of Mount Rosea. The walk takes you through forests and up sandstone cliffs to the top of the mountain where you get 360 degree views of the surrounding area, including Lake Bellfield.
There are several different ways you can get to Mount Rosea, parking on either side of the Grampians Peaks Trail. As well, you can camp on either side (or create a longer backpacking circuit from Hall's Gap), staying at either Borough Huts or Bugiga Hikers Camp.
Starting from Borough Huts, you can park in the campground. The trail is marked and starts to the left of the campground. The hike is 8.5 kms each way, offering stunning views of Lake Bellfield as you walk along the Grampians Peaks Trail.
After making your way back, the Borough Huts are a great place to spend the night, though you have to book in advance.
