While in port on Spain’s sunny southern port in Malaga, escape the city for an enlightening wander through eco-friendly fruit orchards followed by a farm-fresh breakfast of organic juices, herbal infused olive oil, and home-baked bread. During this half-day excursion, your host will educate you on balanced, Andalusian-style healthy living. Learn about sustainable agricultural techniques used to improve the soil’s fertility, provide animal habitats, and grow even more delicious produce—most of which you’ll taste for yourself.

Mangrove forests protect not only Bali’s beautiful shoreline and purify the water but are a rich habitat for marine life, including a crab nursery. Help preserve the future of this fragile ecosystem with a hands-on experience. You’ll join a local host to plant mangrove seedlings and release clusters of crab eggs, which will later hatch into sustainable seafood sold in local markets—a thriving, eco-conscious business.

If your cruise visits Aqaba, Jordan, stop to make a four-legged friend at a local animal shelter for homeless Kaleb Kanaai dogs. This historic breed has been used for hundreds of years as an army and rescue dog known for its endurance, vigilance, and strong owner bond. During this volunteer opportunity, you’ll get to know a pup through feeding, bathing, and playing while learning the shelter’s story.

Oenophiles rejoice. Travelers cruising by Almeria, Spain, can visit the estate of one of the area’s first organic wine producers: Cortijo del Cura. This family-operated winery follows sustainable practices in its vineyards and olive groves, producing delicious organic and antioxidant-rich varietals from their vines. During a tasting in their cellar, sip their Grenache, Syrah, and more while munching on locally grown olives, almonds, cheese, and cold cuts. Salud!
