Seminung is one of the most strikingly beautiful mountains in Lampung and is well-known by those who visit Danau Ranau, the lake beneath the mountain and second largest body of water in Sumatra (after Danau Toba). The mountain is the remains of an ancient volcano which erupted, supposedly turning a wide river flowing at the foot of the volcano into the large lake we see today. There is still volcanic activity on Seminung and most people who come to Danau Ranau visit the hot springs at the base of the mountain. A local guide who has climbed the mountain recently is essential because there are many, many tracks on the lower half of the hillside and no signs whatsoever. Despite being famous in the local area it is not climbed as often as you might imagine and so expect overgrown sections of trail on the higher slopes. As usual in Sumatra, it is best to hike with a minimum of two other people just incase you should be unlucky enough to meet one of the very few remaining tigers in Lampung. Before hiking, remember to visit Kota Batu and ask to be directed to the house of the person who you must ask permission to climb the mountain.
In order to reach the start of the trail at the hot springs you must hire a small boat to take you across to ‘Air Panas’ from either Kota Batu or Wisma Pusri. Arranging a boat is very easy. From Wisma Pusri the crossing takes just under 30 leisurely minutes and is a wonderful way to see the Ranau area. From Air Panas (530m) it is over 1,300 metres straight up the coffee-covered hillside to the peak which is marked with a tiny metal shelter. Apparently there is still edelweiss near the top. In the humid early mornings this climb will take a minimum of 4 hours and even longer if you start hiking later in the day when the sun is at its most ferocious. If the mountain has not been climbed for several months the hike could take a full day (to the top and back).
Local people live as far as 1,000 metres high up the mountain and the area is wonderful for wildlife. You are highly likely to see chipmunks and gibbons and will probably hear the beautiful call of the siamangs. Views of the lake and nearby mountains are stunning. There is a lower south-western peak 500 metres away from the true summit (1,881m) which is 1,804m according to the Bakosurtanal map.
From the top, return the same way in 3-4 hours to the pier and enjoy the (somewhat poorly-maintained) hot springs before taking your boat back across the lake.
Bagging information by Dan Quinn (October 2012)
- Getting there: There are regular buses from Bandar Lampung (Rajabasa terminal) to Liwa (where you can change) and one bus per day direct to Ranau. There is even a bus all the way from Jakarta. There are also plenty of buses from Palembang via Batu Raja. If driving, if can take from between 6 to 8 hours to reach Danau Ranau from both Palembang and Bandar Lampung. Boats across the lake from Wisma Pusri to ‘Air Panas’ cost about Rp 135,000 return but are more expensive if you plan to cross at night for a dawn ascent.
- Accommodation: Wisma PUSRI overlooking the lake is a nice place to stay. You will have to pay two fees of approximately Rp5,000 to enter the complex. Otherwise there are one or two losmen in Kota Batu or, further away, Banding Agung.
- Permits: Not required but take a photocopy of your passport photo page just incase. You are requested to report to villagers in Kota Batu to let them know of your plans to climb the mountain. You may have to pay a small fee at the ‘Air Panas’ pier.
- Water sources: None seen. Take plenty with you.
- Travel insurance: We recommend World Nomads insurance, which is designed for adventurous travellers with cover for overseas medical, evacuation, baggage and a range of adventure sports and activities including mountain hiking.
