"Time + Tide spent roughly six years developing this private island property off the northernmost tip of Madagascar. The conservation-based company is also a foundation, and this property in particular has led a lemur translocation in order to stave off the excessive poaching and sales on the main island. They also lead ecological education programs, seaweed farming, and health-care education for local communities. So all you need to ask yourself is whether you want to save lemur pups and also enjoy a truly fantastic three-bedroom villa on the Indian Ocean. At the same time. Tour-operating veteran Roar Africa is the company to know for booking." (Starting $13,000/night)
