The trail, valley, and beach are pristine and absolutely gorgeous. When hiking and camping, it is essential to respect the sacred beauty of this part of the island. Do not leave any trash, and take in what you take out. Wear reef-safe sunscreen, and stick to natural insect repellents and eco-safe soaps that won’t leak chemicals into the environment. Make sure that you have a permit to camp in Kalalau, as this regulates the number of campers in order to keep camping sustainable, and you can also receive an astronomical fine if you get caught camping without a permit. Keep in mind that Kalalau is sacred to Hawaiians. There are heiaus along the trail, near the beach, and in the valley. These are Hawaiian temples and may be difficult to identify for unfamiliar eyes. For this reason, do not move any stones or alter the environment in any way. Treat the trail with gratitude and respect.
