Fodor's Expert Review Punaluu Black Sand Beach Park

A must-do on a south–southeast–bound trip to the volcano, this easily accessible black-sand beach is backed by low dunes, brackish ponds, and tall coco palms. The shoreline is jagged, reefed, and rocky. Most days, large groups of sea turtles nap on the sand—a stunning sight. Resist the urge to get too close or disturb them; they're protected by federal and state law, and fines for harassment can be hefty. Removing black sand is also prohibited. Extremely strong rip currents prevail, so only experienced ocean swimmers should consider getting in the water here. A popular stop for locals and tour buses alike, this beach park can get busy, especially on weekends (the north parking lot is usually quieter). Shade from palm trees provides an escape from the sun, and at the northern end of the beach, near the boat ramp, lie the ruins of Kaneeleele Heiau, an old Hawaiian temple. The area was a sugar port until the 1946 tsunami destroyed the buildings. Amenities: parking (no fee); showers; toilets. Best for: walking.
