1.要加.如果没有词组climb up,状语从句就缺少了谓语部分.2.如果不用climb up,这个句子也可以说: All the teachers and the students were tired when they were on the top of the moutain.

You should add the phrase "climb up" because if you don't add this phrase ,this sentence will short of the predicate.

估计是输入错误。这里要加climbed up，因为when后面的从句必须是个完整的句字。补充完全就是: All the teachers and students were tired, when they climbed up to the top of the mountain.

加，They the top没有谓语
