Shouldn't the tag mountain be renamed to mountains? It sounds much better for me. I'd rather not say "I'm going to mountain" but "I"m going to mountains".
disclaimer I'm not native speaker, so my impression may be not correct.
Our general rule of thumb is to use the plural for noun tags, so I've renamed it accordingly.
