The below is an old forum post that was closed, but we just went to Semuc and I wanted to answer their question with new information:
Does anyone know if the road to lanquin and semuc champey has improved?
I've seen a few posts about driving there yourself which said it's not advisable unless having a 4x4 but these were all quite old posts.
A few also mentioned that they were working on paving the road. Anyone know if this has been completed?
