Mt Arjuna (3339 m) and Mt Welirang (3156 m)
Both the peaks of the Mt Arjuna and Mt Welirang lie on the same mountain. We can climb Mt Arjuna either from northeast (from Tretes through Mt Welirang), from east (from Lawang), and from west (from Batu-Selecta). From Surabaya take a bus going to Malang and get off in Pandaan then take a mini bus to Tretes. Tretes is a tourist spot. It has a tourist forest where we can find a beautiful waterfall called ‘Kakek Bodo’, and a camping area. Tretes has cool climate and many hotels and inns to rest comfortably. We can start climbing both Mt Arjuna and Mt Welirang, start from PHPA office in Tretes. Trekking towards southwest for about 4 or 5 hours, we can pause and spend the night in about for people looking for sulfur stores. Here we can have water for cooking and take a bath as the water is in abundant. Everyday, about 20-30 workers look for and bring the sulfuric stores to Tretes. In next morning we can start climbing forward to Mt Welirang, or turn left to go directly to Mt Arjuna. Climbi...
