The easist route is, as mentioned in the text, from the south along a long grassy ridge. On this way, you'll traverse Crnogorski Maglic, the tallest point of the whole range (2388). Crnogorski Maglic looks less attractive than Bosanski (the main peak, 2386), that's why it's often neglected by climbers, even though the summit can be reached within 5 minutes from the marked trail (let alone the fact that it's the highest mountain - but of course, Bosanski is the tallest in BiH:) Besides this trail (marked well from the Trnovacko lake), there are at least two other ascent routes on Maglic. One from the Prijevor saddle (western route), one from Ulobici (eastern). Both include rocky sections secured by fixed ropes. The one from Prijevor is extremely steep and breathtaking.
Water is really not very abundant in the upper parts of the range. One cesma is to be found a few dozen meters above the road fork at Mrkalj klade, direction Lokva derneciste. We can call it Nikola Poplasen, as somebody has painted his name on it . If you start in Mratinje (Montenegro) and take the route onto the Ulobici plateau, last water can be replenished at Police. But the Carev do spring offers not only magnificent water but also a fine place for camping with stunnig views in all possible directions.
