A little off track but same road. If anybody has a fear of heights, narrow roads and very very limited areas to pass oncoming vehicles. Going to the Sun will REALLY be a CHALLENGE. On both my trips over this road - I could hear folks screaming in vehicles I would pass - coming the other way. This is a really high, narrow, windy road and you will meet a lot of traffic coming the other way. Some of them will be motorhomes and it will challenge your nerves and driving skills. On the positive side - it is paved and remarkably beautiful.
