Once in the fort you can wander round the rooms and go up some stairs to the first floor. However the ground floor is very overgrown and the surface uneven and it is difficult to see where you are putting your feet. There is a fireplace in one of the rooms. The first floor is less overgrown but there are some very deep holes you could step right into if you aren't paying attention to where you put your feet. Lots of wildflowers were in bloom when I visited in July 2016.
The name Houme Herbé translates into English as "grassy islet". The fort was built in the 1850s and was probably finished c1854.
