The drive takes about 45 minutes to an hour depending on road conditions. The road is unpaved. Find out if the road is open or if you can even see the glacier before you make the trip. In the early summer the glacier can be completely covered in snow. There's a parking area near the end of this drive with a spectacular view of the glacier and surrounding mountains. Breathtaking!
Directions: From Hyder, drive past Fish Creek and keep going. You will be crossing back into British Columbia but there are no customs and I don't think there's even a sign that you enter Canada.
Keep your eyes open for wildlife! This is real wilderness. I saw quite a few marmots (pictured) during the drive to Salmon Glacier.
