The views are great, and as long as you're nearby it would be a shame to miss riding the highest paved pass in the Alps! I've ridden it several times and don't remember the traffic issues some other posters have mentioned. Maybe I'm just lucky. The road up from Jausiers was quite good in 2011. With great altitude the weather can change quickly up there, and we rode up in rain and hail in July, so be prepared.
As is so often true in the Alps, each road is close by other great roads, and it's easy to make a loop that incorporates Bonette with other roads that will provide a very entertaining day.
