One of the best hikes on Kauai, the Kalalau Trail is an 11-mile trek located on the famous NaPali Coast on the northwest coast of the Kauai. The Kalalau Trail is the best way to explore this coastline up close. This is a hike recommended only for advanced hikers and you should come ready for a grueling trek. But the reward at the end is worth every ounce of pain and struggle to get there. The trail offers a gorgeous blend of Hawaiian scenery, from bright blue waters to high mountain peaks and forested valleys with waterfalls and streams. There's plenty of wildlife to see here too, which regularly draws photographers and others with an appreciation for untouched wilderness. Thanks to this rugged and varied terrain, you'll see some of the most incredible coastline views imaginable as you hike. If you prefer a more relaxed setting, Ke’e Beach at the beginning of the trailhead is one of the best places in all of Kauai for snorkeling and swimming as it is protected by reef making it a very safe place. Note: Visitors must have advanced reservations to enter Hā’ena State Park and they are often taken within minutes of being made available 30 days in advance at GoHaena.com so plan accordingly.
