Check for road restrictions. Last year when I was there, there were two zones on the west slope where bicycles were restricted during certain hours of the day. One zone only one direction was restricted, in the other zone both directions restricted.

Some of the shuttle buses last year had bike carriers on the front. Never used one but if I had been stuck for several hours waiting for the time restriction, I might have use the bike rack on a shuttle.

Some of the campgrounds have hiker biker sites that cost less than the regular automobile type sites. I used the hiker biker sites in Apgar and Sprague campgrounds.

If you have not checked elevations yet, the elevation climb up from the west side is a lot more elevation gain than from the east. Attached is a screen shot of my computer screen after I uploaded my GPS elevation data into my computer for the day that I went from east to west over going to the sun road. Day started at a private campground near St Mary, finished at Apgar campground.



You are going to have a great trip.

If you see one of these, I suggest that you do not get closer for a better photo. This was taken with a powerful zoom.
