It's not that it burns when you get close, there is a gap in the barrier in the garden, and if you get out you can turn to dust from aging, it feels like burning. Some girls have managed to reach out, lose limbs or become wrinkled, before coming back in.
I didn't want to spell it all out but yes. The garden has a bit of a gap in it to get through, but you'd have to find it and risk it.
