The hike starts at the tourist pointer lying south of Mazeri village and is marked by white/red rectangles. The trail first heads southeast, to the Bagvdanari village where it turns east and enters Gulichala valley.

After a while, you will reach the bridge (don´t cross it). Here, the road turns into a rocky chute and climbs a bit until you find yourself on some kind of an elevation separating two riverbeds. This ridge soon turns into a large pasture from which you can see ruins of Gul village ahead (and if you look well enough, even the white pointer at the Guli pass far above). Follow the track towards the ruins. First, you will pass some completely destroyed houses, then some better-preserved church.

Keep climbing and one hour later, you will reach shepherd huts (well-known from numerous photos). If you need water, look for the white "2500" sign and arrow showing forward, towards a narrow path in the vegetation. After some 100m, you will find a small spring.

Now it's the time to climb to the actual pass. The path is basically the endless serpentine climbing to the small depression above. It´s marked, but that doesn´t mean you can´t lose direction - mainly because the slope is crossed by numerous cowpaths. And since cows prefer horizontal paths, if you focus too much on "following a trail", you may end up doing huge zig-zags while gaining only a little altitude. Still, you won´t get lost since you will see the pass all the time.

Finally, at the Guli pass (2974m). If you have time and energy (but you won´t probably have neither), you can climb further north to gain an even better view of Mt. Ushba. Ushba is one of the most prominent peaks of the whole Caucasus, its name in Georgian means "Mountain without the path" (also called "The Witch" due to its horned peak).

From the Guli pass, walk south on the ridge, the path slowly descends. Then, after 1 kilometer, the trail turns left, down into the valley. If you have a good tempo, you can keep walking south on the ridge and climb Mt. Guli (2925m). It takes only 40 minutes, views of Ushba are great and there are no people around (so it's an even better place for a lunch break than the actual Guli pass). But, again, unless you are a fast walker or you reserved 2 days for this trek, you probably won't have time for this detour.

The descent into the valley is pretty steep. At the elevation of 2500m, the path turns northeast and starts traversing the hillside. Then comes technically the most difficult part of the trek - crossing of Pushkueri river. The river itself flows at the bottom of a deep gully - during the early summer, it´s filled with snow which makes the crossing easy but once it melts, thing get more complicated. Descending into the gully from the side of Guli pass is easy, needs only some simple climbing. To get out, don´t try to follow the original trail destroyed by the landslides, the terrain is too steep there. Instead, follow a riverbed for some 10 meters (or less or more, it all depends on the status of the snowfield) and then climb up onto the trail once the terrain becomes more navigable.

From here, follow the narrow trail traversing the hillside towards Lamaaja ridge. You will pass some smaller streams as well as numerous blueberry bushes. On the ridge, your small trail will connect the major dirt track leading to the Koruldi lakes. But you probably won´t have time to see them (unless you plan to camp there) so just turn right and continue south. You can either stay on the track all the time (this route passes a water spring) or take a shortcut through the shepherd's huts. Just don't forget to turn back from time to time, Ushba should soon become visible right behind you.

After some 30 minutes, you will come to the shelter and cross at the top of Tshakazagari hill (2200m) over Mestia. Keep following the large dirt track heading down to the town. At the elevation of 1850m, turn right from the large road onto the smaller trail going between the wooden fences (there is also a tourist pointer). This trail will lead you all the way to Mestia.
