It has been years since I hiked camelback and not has it changed. They now have a roundabout at the entrance, this makes the flow of traffic much better. The restrooms and parking lot has been updated and they even added another drinking fountain. Because it is such a popular trail parking can be a nightmare but persistence always guarantees a spot.
The trail has been updated too, it has more trail signs and they even added a couple informative signs along the way. The trail is described as extremely difficult but as a seasoned hiker it can be like a walk in the park. The most important thing is to take your time and make sure you have enough water.
