Answer:
¡Tengo una idea para nosotros en este viaje! Nos gusta caminar y estar en la naturaleza así que viajemos a la Patagonia en Argentina. Será una oportunidad de pasar tiempo juntos.
Step-by-step explanation:
Viajemos comes form the verb viajar and is conjugated in the first person of the plural in the subjunctive. In Spanish the tense called "subjuntivo" is used to express a desire, a possibility or a doubt, almost always referring to the future. In this case, it's as if the person was saying "let's travel to the Patagonia". It's kind of a proposal.
