Although my leg injured during this climb nevertheless I felt happy to reach the summit of Mount Arjuna or Mount Arjuno (Surabaya pronounciation)
From the mountain peak of Mount Arjuno I could admire the volcanic eruption of Mount Semeru at every 15 to 20 ninutes
this route may be the hardest one. no water along this route except at Wonosari. The total time to climb this mountain take 8 hours. And if we go down back this route take 5 hours. but if we take Summit - Sumbergondo to route back, it would be 7-8 hours to get the finish.
this route is almost 50-70 degrees in slope.
