Just a reminder on the cycling restriction hours, when you go up to Logan Pass, presumably you want to start to go down the other side before 5pm. Thus, because of the cycling restrictions you would want to get to Sprague or Apgar (or elsewhere?) before 3pm, thus leave Logan pass early enough. Thus, plan to start your climb up Going to the Sun early enough that you can keep to a schedule that complies with the cycling time restriction. And if you wanted to stop at the Lake McDonald general store, you would need adequate to still bike to your planned destination by 3pm.

In 2012 when I was there, on the west side there was road construction, and a long section of Going to the Sun Road was one lane traffic. Meaning, we had to stand there for a long time in a waiting line part way down on our descent. When you enter the park you might want to ask if there are any road construction projects or other activities going on that could cause a delay.
