Hiking Tips

Heading into Kauai’s interior and remote terrain offers some of the most beautiful backdrops in the world. By doing a little planning and being prepared, you will make your hiking trip one of your best Kauai experiences.

  • Hiking Plan Always tell someone where you are hiking (name and location of trail) you plan to hike and when you plan on returning.
  • Water  Drink one-half to one full quart of water or sports drink each and every hour you are hiking in the heat. Carry your water bottle in your hand and drink small amounts often. Make sure if you are drinking water from any streams or freshwater sources, you purify your water with a purifier that is certified to filter microbial Leptospirosis and  Giardiaare that are present in streams and standing water.
  • Food: Carry high-energy, salty snacks as well as meals. The hike out is much easier when you provide your body with enough calories to support the extreme physical activity you are engaged in.
  • Weather: Check the weather before you set off on your hike. Kauai Weather Forecast
