Cemoro Sewu is the shortest summit route of Lawu, but steeper than other hiking routes of Lawu. While Cetho route is more natural and longer approx 16 km, the ecosystem of Savana and mountain rain forest are more attractive along this route, and opportunity to discover temple group of Lawu is available at the end of the trek included Temple Kethek and Temple Cetho. To discover more temples, it's take more 3 hours walk from Cetho to other temples such temple Suku.


The initial headtrail is right at entrance gate of Cemoro Sewu, more flat and very easy walk on path paved with stone along pine forest, then enter to farmland ecosystem uphill. As we get higher over 2200 m, terrain get more exposed due to less tree and therefore more windy. This route section is more rocky, and we passed Batu Jago, an unique rock rising up look like ayam jago (

cock ). The route then down before arriving at Watu Gedek, the Pos II which's indicated by towering cliff on right isde of the route with flat space for setting several tent in front of the cliff. This site is more protected from wind, and therefore considered as good space for overnight.  

From Watu Gedek to Watu Gede, the Pos III, it's take normally 1 hour trek. This Pos indicated by boulder on left side of the route while on right side is a shelter. From this Pos to Pos IV, it's take 1 hour
hike through steeper route which's still paved with stone and some parts are protected. Along the way, sometime get smell of gas sulfur. Pos 1V is more and more exposed, no shelter her but flat space for break is available. The view is rewarded as we get closer and closer to Pos V passed Sumur Jolotundo.

Route from Pos V is broad flat path on edge, still paved with stone till near by Sendang Drajat where warungs selling food and drink are available.From here Hargo Dumila peak is visible and to reach it, we need several minutes trek head for T-intersection way,turn left and follow the way up to the peak. On dry season, this route section is very dusty.


The descent head for Cetho is done by following the same way till T-intersection way, then turn left. Along the way, we passed Hargo Dalem, the down to Pasar setan and enter to pine forest on edge till border of pine forest and Savana. The route on this section is natural without paved stone. This is broad savana field between two hills that end at border of mountain forest of Lawu. 

As we enter to the forest, the route is down heads for Pos V, there is no shelter here,but it marked.From this point, follow the straight path,then steep downward and cross to another ridge. The Pos IV is on ridge. The valley on left side is good landmark along the way down via this route.

Mountain forest get more dense below Pos III, more slippy and narrow path, some root of trees come out on soil surface that make this route section more and more slippy.Below Pos II, some part of the route is blocked by falling trees that make our progress more difficult with backpack on our back.

 Pos I is too close from Pos II,just 30 minutes way down and therefore there is no need to take break here. At border of mountain forest and local farmland, there's T-intersection way, turn left heading to temple Kethek on ridge, and to reach Cetho follow the slippy path down then up to temple Cetho on different ridge.At cetho area, warung selling food and drink as well as homestay are available.To proceed the trek from Cetho to temple Suku, it's take another 3 hours.

Cemoro Sewu route is attractive for most trekkers, even on wet season. As the path is paved with stone, then the route is not so slippy. Shelters are available along the way at Pos Bayangan before pos I, also at Pos I,II and III.While Cetho route is best on dry season.

SAR team normally standby at basecamp,specially on high season.They are mostly volunteers. Medical center available at district, while closest regency hospital is at regency Karanganyar.Karanganyar is about 27 km from Cetho, 20 km from Suku.
