A: Pack lightly for your Kona vacation, as the weather is mild and balmy all year long. Think lots of bathing suits, sandals, and summer attire. Pack a light waterproof jacket for hiking or exploring rainforests. Bring some warmer clothes for higher elevations of Waimea and Hawaii volcanoes at the national park. Casual dress clothes and resort wear for any local onsite resort strolling or dining. Of course, you can always purchase sunblock, hats, and flip-flops right here at the hotel.
