En Route


At central Java, trekking basecamps are mostly a home of local family
living on slopes of volcanoes.They are normally located at last village
on slope of volcano.The basecamp play important rule during initiating
phase of trekking development in the area until nowday.They are like an information center where hikers/trekkers ask about actual route condition,newly weather condition,permit arrangement info and so on.Here...hikers/trekkers normally take break,even overnight rest,
and do final preparation.

Some basecamp also provide drink and food as it is on order basis in rational prices, also some souvenirs and equipment-accessories for sale.On some volcanoes, some basecamp consist of good building built by Indonesia government,and also Homestay/GuestHouse provided by the locals on
trekking base of the volcano. 


A camp site is normally a flat wide area accommodating 1 - 4 tent/s, even more on some popular volcanoes in Indonesia.Mostly on elevation around 2000 m, some of then even higher up to elevation around 3000 m,and little of them below 2000 m.Camp sites located on left and or right
side of trekking routes.Some camp sites located at once point of POS. POS is normal breaking point, most of them completed with shelter for protection in case of rain or bad weather and normally functioned as overnight site too.On some cases,POS also normally functioned as
Rescue Pos in case of rescue operation on volcanoes due to incident experienced by hikers/trekkers.

Some of POS are only wide flat area without shelter, but more clean from rubbish since hikers/trekkers less concentrated on the area than sheltered POS ones.LAWU either via Cemoro Sewu or Cemoro Kandang routes possessing many shelters en route while SUMBING via Garung has no shelter so far (2013),as well as MERBABU en route of western flank.MERAPI en route of northern flank has two shelter built recently 2014.While SLAMET via Bambangan has several several shelters too.SUNDORO/SINDORO sometimes has temporal shelter built by locals (2012).


The hiking trail environment are mostly the same in ecosystem type,consisted of local farmland then enter to mountain cloudy forest ecosystem on ridge of the volcanoes.As we go higher crossing the mountain forest ecosystem, the environment is gradually changed in to different one as we come to sub alpin ecosystem through more stony section of the trail, then cross the border of the vegetation and volcanic zone where the ridge is more exposed and the path is more stony either solid or unstable surface.
On some active volcanoes, as we get closer to the summit the the volcanic environment are mostly dominated by gravel, some boulders,some sharp rocks even sandy loose surface on some volcanoes.On old volcano, the summit is normally still grassy and some other adapted plants still found while the young ones 
are not.

                                          EN ROUTE STEEPNESS:

The trail on old volcanoes is more flat but longer ridge up and down hill.While on young volcanoes, the trails are steeper with less flat space along the trail.The young volcano is more conical in shape which is indicating more incline of the summit trail...more gradually constant incline, vary angle approx 40 - 65 degrees.

                                    EN ROUTE DIFFICULTY

The trail is typically straightforward, required only to walk on most section of the trail. As the trail get steeper,using a hand is occasionally required for supporting and keep the balance while moving upward, care is needed in order to place foot safely.

On crux of some volcanoes terrain,the trail required you to use hands in order to facilitate upward movement.No need to search around  hand and foothold are plenty available along crux section.Most hiking trails on volcanoes of Yogyakarta and Central Java are marked, but the crux section is without protection except trail of Lawu via Cemoro Sewu.

                           EN ROUTE VOLCANIC ALTITUDE:

The altitude of active volcanoes of Indonesia is intermediate to high in elevation, the highest one is volcano Kerinci 3805 m.then Rinjani 3726 m, and Semeru 3676 m.In Central Java and Yogyakarta,the altitude of volcanoes range from 2900 m to 3428 m with the basecamp as hiking starting elevation ranging approx 1400 m - 1900 m ( different from one volcano to other).

We normally do gradual approach to those altitude for more healthy and comfortable hike as in fact Acute Mountain Sickness in it's mild form often can occurs around 2.450 m or higher but can occurs on even lower altitudes (each people is different , by common symptom is a headache, then at least one the following symptoms is present; nausea,sleeplessness,lack of appetite, or malaise).
