Sleeping Giant (Nounou) Trail – Kauai, Hawaii

Sleeping Giant (Nounou) Trail – Kauai, Hawaii

Kauai is known as the garden island and for good reason. Everywhere you turn, sits a lush tropical landscape. No matter what you’re into, this island has it for you.There are many beautiful beaches to relax on, but choosing which hike to do can be more challenging. Some will take you the whole day, while others a few hours. 

The island is small, but has lots to offer. If your looking for a shorter hike that will give you amazing views, then make sure to try out Sleeping Giant (Nounou) Trail. As you hike to the top, you will be treated with views of Mt. Waialeale, the Wailua River, and the ocean. This hike is perfect for a quick adventure into the tropics of Kauai.   

The first part of the trail will have you hiking through tall trees and this is consider the easier part.

West Side Of Sleeping Giant Trail

When looking for a good hike, a few locals told us to try the Sleeping Giant hike on the west side. We were not disappointed at all. The changing landscape was amazing to hike through. 

The parking lot is small for this trail, so come early or leave enough time to wait for someone to be done. The first part takes you through tall Cook Pine trees, as you slowly gain elevation. In addition, you will come across an intersection where you can hike the Kuamoo Trail

To stay on the Sleeping Giant Trail, make sure to stay left. From here the trail is more open to the weather, so when it’s wet out, then be prepared for mud. This is where the difficult part comes in if you hike it when it’s muddy. 

Keep trekking along until you hit the first plateau, where you will see picnic tables. Rest, drink some water and enjoy the views over Wailua. 

If you’re up for it, then continue on the trail for another 10 minutes to reach the top for even more gorgeous views. As you hike back down, make sure to stay on the west trail if you want to reach your car again.

What To Bring

Always plan your hike ahead of time. The weather can cause dangerous conditions for any experienced hiker. 

  • Water You always want to drink more water than you should and carry more water than you would. (This one has become engrained in us, due to living in the  Arizona desert). A good rule is for every hour your hiking, you should consume at least 1/2 liters of water. 
  • Clothing Dressing in layers is the way to go. It can get very hot and humid on the trail, so it is best to wear cloths made from Rayon, Linen, or cotton. 
  • Footwear Proper hiking footwear is needed that has good traction when hiking in mud and rocks. 
  • Snacks The hike up can take some energy out of you and it’s best to replenish with high calorie and protein snacks.
