G19 is a short trail that has a number of rock rolls and drops. There are a number of bail-out points along the way in case the trail gets too hard. There are some steep rock faces that can be rolled, but there is definitely a little bit of commitment required.
The beginning of this trail has a steep rock roll. If you don't feel comfortable at the start, then it is best to turn around at this point since it doesn't get any easier.
