Lots of springs on the road between Ljuta and the turn-off to Lukavac (but no good campsites until that turn-off, due to mine risk). Climb to Lukavak is fairly easy. Route from Lukavac to Kalinovik is unmarked until the turn-off to Treskač, but the GPS route follows a well-made old path along the ridge. Simovića kuće is lovely and welcoming, with incredible food (first house on your right heading south into Vlaholje; 60 KM for two people lodging, dinner and breakfast). Kalinovik has three small shops to resupply, however they don't have a great range of hiking-appropriate food. There is an ATM and bank next to Moskva Restaurant. Both Moskva and Café Leon were hiker friendly. 5 km south in Jelašca is also the B&B at Lalović family which is a beautiful handmade cabin made with Via Dinarica walkers in mind. Also excellent food (60 KM for two people lodging and breakfast; dinner may be another 10 or 20). Both Simovića and Lalović were happy to cater vegetarian.
