The path is very exposed to the sun. Therefore bring enough water with you. The last drinkbale water can be found when you start from the Kocha v Krnici just after you exit the forest and enter the rocky path, on the right. The stream is very loud usually and therefore not difficult to find.
Further up, there are two - three additional summits. Gamsova Spica has a nice forrest good for a break. Be very silent there because you can see gams (gams = mountain goat). Also, there is a splendid indentation in that particular summit with a great view.
Still necessary to cross Lipna Spica and Lipnica before the summit pyramid itself.
The path from the Kocha v Krnici is excellent for the ascent and the path via Kachji Greben is excellent for descent.
Also, if you wish to enter excellent walls of Shkrlatica, Rogljica, Rakova Spica, Mala and Velika Ponca you can start from the Kocha v Krnici and thereafter leave the path to Shpik on your left and come to Bivak I which is a good starting pointing for further alpinistic explorations.
