Yala Peak is very close to Tibetan border indeed, the one of the border mountain is right next to it (connected by a ridge). The view from top includes Shishapangma, the only eight-thousand completely in Tibet. Usually climbed in 2 days from Kyanjin Gompa (3900m), camping at Yala Kharka (4600m). It's also possible to do it in one day, without camping, but it's a long day with a pre-dawn start. Climb is relatively easy and non-technical, but at some places you have to use your hands, and ice axes are useful but not essential. The last 15 meters to the top is a steep rock pyramid, hands definitely required, and 1500m to fall if you are really unlucky.
