Begin the trip with a visit to the lush greenery of the botanic garden, an expansive 625 acres featuring more than 200 rare and endemic plant species. Take a guided tour to learn about the medicinal qualities of the plants and the conservation efforts. If you are interested in hiking, try the Ha'iku Stairs, AKA "Stairway to Heaven".
Discover a diverse range of plant species such as heliconias, bromeliads, and hibiscus. The arboretum offers a 45-minute narrated tram tour around the garden for visitors to learn about the history, beauty, and relevance of the island's flora. If you are an adventurous type, snorkel and swim in the secluded Waimea waterfall.
End your trip with a view of the Wailua Falls. The double-tiered waterfall cascading down a lush jungle valley creates a spectacular sight. Take the short 0.4-mile hike to the base of the falls to snap some beautiful photos. If you are up for more adventure, try the Kayak+Wailua Secret Falls Hike package which offers a unique experience of paddling upstream, hiking through a jungle and getting to view the secret waterfall.
If you have more time, visit the Polihale State Park's beaches on Day 2 so you can grab some sun rays! Don't miss out on the opportunity to sample some local fare from stands along the way.
If you have less time, consider skipping the Kayak+Wailua Secret Falls Hike package. Spend the day relaxing on the shores of the Poipu Beach, known for its snorkelling and surfing spots.
