🌿 Aloha Hiking Tips:

• Respect ʻāina (the land) — stay on trails and pack out all trash.

• Many trails are on private or culturally sensitive land—always research access and closures.

• Start early to avoid heat and crowds.

• Bring water, sunscreen, and proper footwear.

• Avoid hiking alone or during heavy rain (flash floods and mudslides are real risks).
