Kalapaki Beach on the outskirts of Lihue Town in the south east corner is a good beach for frolicking in the sea as it is fully protected by the natural bay and man made harbour. Kalapaki has great swimming and body surfing, some surfing and the beach is a popular spot for locals and tourists alike.
The east coast of Kauai is excellent for strolling and beachcombing along the sandy beaches between the town of Kapaa and Wailua. However, the sea along this coastline has unpredictable currents and dangerous winter surf. There's usually good surf at Kealia Beach north of Kapa'a Town. Kapa'a Town has a long stretch of beach, although it is very narrow in places.
Two spots noted for safe swimming are at Lydgate Park south of Kapa'a Town and Kalapaki near the airport town of Lihue in the south east corner of Kauai. The best of these for families and tentative swimmers is Lydgate State Beach Park at Waimea. Here, two lava pools have been created to make safe swimming and snorkelling even when the surf is high. There's also an excellent kids playground behind the beach and a historical park with ancient Hawaiian landmarks and petroglyphs.
