Bougainvillea-covered balconies, jungles teeming with wildlife ... there’s more treasure here than the Spanish ever dreamed of. Step back in time to Spain’s colonial heyday in Cartagena and Santa Marta, where museums glitter with pre-Colombian gold and jewelers display fresh-from-the-mine emeralds. Join the birds in the rainforest canopy and caimans in thick mangroves. Dine alfresco beneath a colony of stars and toast the perfect antidote to winter.
