Glacier in April: what the park service says

April is when the plows go to work on Going-to-the-Sun Road. The park says spring snowstorms and avalanches often force crews to clear the same stretch twice, which is why it sets no opening date for the road over Logan Pass; the full road has usually opened by late June or early July. While plowing goes on, the cleared section past the gates is often open to hikers and cyclists only, a season that usually starts in early May, and the park's plowing status page shows where the crews are working. Higher trails can stay snow-covered and dangerous until late June, so check the trail status and closures pages before you set out.
