About Crater Jr.
Crater Jr. is a shallow Islamorada reef near the Eagle with sand-filled valleys, coral heads, and an easy second-dive feel. It works well for relaxed guided diving and photography when you want clear water, simple terrain, and steady reef life instead of a deep or technical plan. The route stays visually open, so the dive is more about reef texture, reef fish, and easy boat logistics than depth.
