Yes, it is indeed. I rode on it yesterday. The route we take is to start at Encanto Park in Duarte, ride along Sierra Madre Blvd to GMR, then up to Glendora Ridge Rd out to Mount Baldy Village for breakfast (just made it yesterday.) Then we come back the same way. Fantastic 57 mile ride with 6100' of climbing.

GMR has some problem spots because of the severe rains. No problems at all for cyclists, but I think the road will be closed for a long time while they fix the washouts. The road was pretty clean, considering. There was a fresh landslide that forced us to get off and carry our bikes, but both roads were in better condition than I thought they would be.

For those in the area, don't miss out on riding on these roads when there's no traffic*. They are truly the epitome of fantastic cycling roads.

*We did see one Ranger/Fire truck up there. So you can't just ride willy-nilly all over the road, although you don't have to worry about all the motorcyles going by.
