You will only be able to get so far in a motorhome. You will need to check. Videos on youtube are available of the road this one is ours there are better ones but it gives you an idea of the width and height available on the road. The bridge area is the only place you are likely to meet anyone. Scramble down from the village and it is 20 minutes to reach the river but ye gods it is nice and completely by yourselves cos no one else is that stupid. Take a picnic and enjoy the sun and a dip. Use maps.me or mapy.cz to locate the path. I think but am not positive a motorhome can make it to the village and can park there but it is a no through road for anything bigger than a mini !
