Nestled on the slopes of volcanic Mauna Loa, the port of Hilo offers visitors a path on which to step back in time. Your Carnival cruise to Hilo alohas you to low-key Hawaii, where island life moves at a slower pace, people still greet each other on the street and blossoming flowers and macadamia thrive, all to the delight of the senses. A Hilo cruise transports you to this Hawaiian town draped in lush tropical foliage, overlooking the placid waters of Hilo Bay.
