Ojstrica

From this point you have the best view of Lake Bled, the castle, and the island (postcard panorama). At the lookout point is also a bench from which the wonderful view can be enjoyed.

The viewpoint from the summit Velika Osojnica is beautiful. Since there is a lookout further down the mountain, you are mostly completely alone at this vantage point on the summit.
The way up there is a beautiful forest path and the extra meters are absolutely worth it.

Be aware of muddy and steep trails - especially during or after rain(!)
The view is great!

Nice view of the lake. However, quite busy.

I loved this monster staircase

Bled; Olympic competition site for rowing and canoeing, embedded in the nature.

Best viewpoint on Lake Bled.

Best viewpoint on Lake Bled.

The high east side is very beautiful and recommendable. The west side down is less beautiful but ok as a round trip. View is very nice!

While you're here, also visit Mala Osojnica, the view from there is even better IMHO.
