Trying to find a movie based off of the ending

I am trying to find this movie where this group of young boys(maybe like age 12) all hangout in the summer and at the end they go cliff jumping into water. They jump from this cliff that they were told to never jump off of because it is super high up and dangerous. They idolize this one guy that successfully jumped it years ago. At the end when they jump off of this cliff, one of the boys ends up dying due to internal bleeding.
For some reason I think the cliff name is included in the movie title, and I think the cliff name starts with a ‘G’.
Does anyone know this movie???????
