The southern shore of Kauai is the area between Maha'ulepu Beach in the east and Lawa'i Bay in the west.
It includes the expansive Poipu Resort area with its excellent hotels, resorts and condominium resorts and some of the world's most beautiful beaches with beautiful sunsets and sunny days. You may even see a monk seal sunbathing on the beach in the late afternoon.
The new Kukui`ula Village shopping center offers excellent shops, galleries and restaurants. A short drive along the coast will take you past Koloa Landing and Prince Kuhio Park to Spouting Horn where you can see one of Hawaii's most famous blowholes. The nearby National Tropical Botanical Garden offers tours. Their Allerton Garden Tour is the only way to access beautiful Lawa'i Bay.
A short drive inland will take you to historic Koloa Town, once a major plantation town in the Kauai sugar industry. Today there is an excellent History Center and numerous shops and restaurants.
If time allows, head further inland and back to Rt. 50 (Kaumuali'i Highway). Head west and explore the lovely towns of Hanapepe and Waimea. Be sure to stop by Salt Pond Beach Park near Hanapepe, one of Hawaii's loveliest beaches.
