After searching for information on the Little Desert Discovery walk a couple of months ago I finally managed to get up there to do the entire walk over 4 days. Information on this walk is as scarce as a mallee fowl but Parks Vic assure me they are in the process of updating their brochures etc. I was unable to find any detailed maps and given the Vic Topo maps looked like I would need 4 maps to cover the whole walk I ended up relying on a Parks sketch map from 2002 (previously mentioned in this thread) and a GPS. The track is well maintained, marked and easy to follow so even without detailed maps there were no concerns. The entire walk is 75kms (not 84kms as listed in the information)
Day1Horseshoe Bend to Yellow Gums Camp - 21km
We drove to Dimboola and parked the car at Horseshoe Bend about 7kms out of town. This camping area is on the banks of the Wimmera River and the walk initially follows the river for about 5 km meandering through the river redgums. The track then turns south west heading towards Eagle Swamp which is 11km from our start at Horseshoe Bend.

We stopped for lunch, then continued on the sandy tracks toward our overnight stop at YellowGums Camp. The track was well defined and with very little recent rain extremely dry. Plenty of birdlife including mobs of emus and a few wildflowers. Yellowgums offers a good campsite (take sand pegs), shelter, fire pit (fires only permitted April to October inclusive) and water tank. The tank was half full of fairly foul smelling water but was ok after boiling.
Day2Yellow Gums Camp to Kiata Campground - 21km
With temps down to 1 degree overnight I was really happy with my new Malachowski Climber 600 sleeping bag. Its first outing and I was toasty warm all night. I had taken along my Tarptent Moment DW to save weight and while it was cramped with two it was ok with the wife as a walking partner.
We packed and headed off on a very sandy track. Unfortunately the walking track resembled a dirt bike track with huge ruts and loose sand. Despite signs everywhere for no motorbikes some people have no care or respect. This made walking fairly slow going and my better half was struggling by the time we walked the 9km to Salt Lake. Thankfully the track improved after Salt Lake and some steady climbing to Trig Point (6km from Salt Lake) gave us chance to break for lunch and enjoy the 360 degree views from the viewing platform.

A further 6km to Kiata campground saw us finished by mid afternoon for some down time. While the Kiata campsite had quite a few car campers the area is huge at it was easy to find a spot of our own. Emus wandering around the camp, and good facilities this spot is worth a visit even if not hiking. There are numerous tanks at Kiata so plenty of water.

Day 3Kiata to Mallee Camp - 20km
Great weather again greeted us as we made our way south then south west toward Pumpjack Dam. The track in the northern part of the walk was firmer than the first couple of days so walking was more comfortable. A quick stop at Pumpjack Dam (10km from Kiata) and we pushed on. The day was getting warmer and although only in the low 20s with virtually no shade it had started to feel hot. This would be a much tougher and less enjoyable walk in hot conditions. We reached the intersection of the Discovery walk with the Wallaby track (15kms from Kiata) stopped for lunch then meandered into Mallee camp. Again a good camp setup with hut, tank, fireplace and drop toilets. The campsite is next to a dam and plenty of birds were coming in for a drink on dusk including a huge emu. We just settled for a drink of red wine!

Day4Mallee Camp to Horseshoe Bend
Shorter day today with only 13km back to Horseshoe Bend. Even so with the promise of higher temperatures we made an early start to be finished before the heat arrived. The well maintained track took on its now very familiar look of firm sand, in very low scrubby and dry vegetation. About 5km from Mallee Camp we bumped into a mountain biker who had headed out from Horseshoe Bend. We strolled the rest of the way back to where we started.
I don't think this walk sees too much traffic. The visitors book at both Yellow Gums and Mallee Camp hadn't been updated for 2 months. Parks Vic (and/or volunteers) have maintained the track well and it is very easy to follow. My concerns of not having detailed maps were unnecessary. At times the walk can be a bit monotonous and it would not be at the top of my best multi day hikes. That said, it was good to visit a different terrain (it is the desert and its meant to be flat, sandy and dry) and the campsites were all excellent. I'm happy to answer any queries about the hike or if you would like GPX files send me a PM.
