Changi Tower 5820-M situated in Nangma Valley. It is an eight hours walk from Kande Village which is 5 hours drive from Skardu. Changi Tower is part of larger Amin Massive and enormous granite block in the upper reaches of Nangma Valley. The Amin Massive includes Amin Peak, Changi Tower, and several other unclimbed spires. Most of the rock within Nangma Valley is either granite, gneiss, or schist; however, the predominant rock type is granite, and there is lots of it.  

An Australian/New Zealand party also made first ascents in the Nangma Valley. The all - women's team of Abby Watkins, Vera Wong, and Nicola Woodford climbed Excess Baggage on the 5,300m Changi Tower. The route works left up the main rock wall to climb a prominent crack system and snow slope above to the main summit. Difficulties were rated at 5.10 and A2+. Watkins and Wong currently hold the women's speed record for an ascent of the Nose on El Capitan (16 hours and 40 minutes).
New Zealanders, New Norton, and Paul Weber, also climbed a route on the Changi Tower, starting to the left of Excess Baggage up a slanting corner system then cutting through the last-named route to finishing on the North Summit. The climb was completed in 10 days at 5.10 and A1, involved 26 pitches and was christened " Just a Quickie " as the pair had originally thought it would provide a quick warm-up climb before heading off for greater things.
