In the Hunger Games beach scene, Katniss found herself on the sandy shore. The sun was beating down harshly. She was on the lookout for any signs of danger. Peeta was nearby, gathering some strange shell - like objects that could potentially be used as weapons or tools. The waves crashed loudly, and the salty air filled their lungs. She knew they couldn't stay in the open for long, but for a moment, they were mesmerized by the beauty of the beach, forgetting the horrors that awaited them in the arena.
I'm not exactly sure where it was filmed. It could have been anywhere with a nice beach and suitable filming conditions. Maybe you can check the movie's credits or some behind-the-scenes information for a precise location.
There could be battles between tributes. For example, two tributes might fight over a valuable resource found on the beach, like a fresh water source or a unique weapon washed ashore.
I'm not sure which novel or storyline you're referring to. If you can provide more information or context, I will try my best to provide you with a more accurate answer.
