We went in the morning E to W. Due to the conditions on the summit shown in the background of http://tsteven4.qwestoffice.net/
we rode to the top from the west on a rest day we took at Lake McDonald. Again, we rode in the morning. It is worth doing twice in a row! You can see other photos here http://tsteven4.qwestoffice.net/gallery/index.html?albumid=5094829015672537185&si=1
dated 2007-7-19 and 2007-7-20. Nice hiker biker setup at Sprague Creek on Lake McDonald.
"Can I ride my bicycle on the Going-to-the Sun Road?
Yes, but there are some exceptions. From June 15 through Labor Day, the following sections of the Going-to-the-Sun Road are closed to bicycle use between 11a.m. and 4 p.m.:
* From Apgar turnoff (at the south end of Lake McDonald) to Sprague Creek Campground
* Eastbound from Logan Creek to Logan Pass.
Due to ongoing road rehabilitation on the Going-to-the-Sun Road, portions of the roadbed may not be paved. Bicyclists should use caution riding on gravel portions of the road."
