Do you mean the trail that leaves from Indian Flat Campground (near Cedar Lodge) that is shown on the USGS topo? If so, that is an old road and has been accessible for a while, with some partially overgrown sections near Hite Cove. I believe the fire burned hot near Hite Cove so it will be interesting to see what it looks like there. Though most of the understory is likely gone, there could be downed trees over the road making travel more difficult.
Often times after a fire there is an area closure. I haven't seen one yet, but the incident is still on going. Highway 140 to El Portal just opened this morning. I'm not sure on how soon you are planning on going, but I would wait a little bit. With big fires there can be unburned patches and hotspots for many weeks afterwards. Staying on the road would likely be safe but still a concern.
Otherwise, I am excited about some of the other trails/roads in the burn area that were overgrown and will now be accessible in the fall. Plus with all the handline and dozer work up there, some of the trails and roads might actually be improved.
