In the 1960s and 1970s, when southern eruptions were not a regular occurrence at all, a number of the places to stay developed legendary status. Vogels was the place to stay, and regular updates of Bill Moon's Indonesia Handbook would have details of the southern approach to the night walks to the peak of the Volcano.
The 1990s and 2000s south flowing eruptions and gasses have tended to make a significant dent in the liveability and general access to Kaliurang.
It is advisable to investigate the condition of the volcano, and general accessibility of the town.
When the eruptions were not spewing southwards, it was also the location of one of the 4 or 5 observation posts of the Volcanological survey. The post is named after the hill, Plawangan - and when there is clear air, and no euptive gases heading south, a very good view of the southern slopes of the volano are possible from the Plawangan hill. Another hill just west of Plawangan is Turgo, where a mysticall and significant islamic saint is buried.
There is a fee entrance (3000 per person on weekends) to access the Kaliurang village.
- In the nearby village of Kaliadem, there is a Merapi volcano museum and a jeep or motorbike trail(Kinahrejo) from where tourists can see the destructive forces that shaped the landscape from the last major eruption.
Ullen Sentalu MuseumUllen Sentalu is a museum about the Yogyakarta royalty with lush gardens. There are collections of personal items, letters, artwork, and batik that are available for viewing. English speaking guides are included with the admission ticket price.. If you have kitas visa as a foreigner better bring your passport to get a local price.
Trekking around the base of Mount Merapi
There are some interesting and not too tough treckins you can do there.
Ticket access allows visit of both parks during 1 day(you may need 3-4 hours to visit everything).
Ticket for locals or students(including foreigners that study in Indonesia or with kitas): 5000rp.
Ticket for foreigners: 150.000rp
Indications inside the treckings are quite good and you can't get lost, also you can use the offline maps like Maps.me or OSMAnd for better guide yourself in the treckings.
Tlogo NirmoloThis forest includes the visit of many Japanese caves(Goa Jepang) constructed during the second world war to be used by the japanese army to protect from the allies attacks. There are a dozen of those not profound(10m max) caves and there is a man that can rent you some lightorch(although using your phone's torch would is enough). It takes 30min trecking to the caves from the entrance.
Also a much steep treck to the summit of the Plawangan hill is available(ask the entrance gard if the visibility is good). (40min).
Tlogo MuncarThis park is more visited by families and indonesian couples since it includes a quite magnificient waterfall called Muncar(id: Air Terjun Muncar), after raining the waterfall is more interesting since it can bring lots of water. Also there is a 25min trecking to the top of the Pronojiwo hill with great views towards Merapi.
Also on the road to Kaliurang, at the Pakem village, there is a banana market(5 or 6 stands on the right side) where you can find the cheapest bananas and avocados.
- The town is basically at the end of the road, any further go next would be down the hill and return to Yogyakarta.
