FEES FOR CYCLISTS

For those visitors who wish to bike down to the Postpile, bicycles are allowed down the road free of charge.

The Reds Meadow Road beyond Minaret Vista twists and turns for about 6.5 miles and 2000 vertical feet down to Devils Postpile. The road is paved, however, it is very narrow and cyclists should be aware of debris. It is a beautiful and challenging ride, particularly for those who make the trek back up to the Vista. For those looking for just a downhill ride, consider riding the shuttle bus back to your vehicle at the Adventure Center at Mammoth Mountain.
