As far as eco-travel goes I am partial. A few years ago I accompanied my grandmother on several eco-adventures in Africa, Central and South America and New Zealand and all were fantastic educational minimalist trips and not what I would consider luxurious. I need my creature comforts and in some locales you can actually have an encounter with an uncomfortable creature. While traveling in Botswana several animals / spiders ended up wandering their way into our tent and it was very nerve wracking. There are Four Seasons properties that offer eco-excursions from the property. I believe the Four Seasons' in Costa Rica, Uruguay, Seychelles and Mauritius all offer eco-excursions of some sort.

Also remember, a resort my have television, a dining pavilion, a bar, swimming pool, etc. but sometimes they do not have the service to match. Traveling in El Salvador is relatively safe compared to Mexico, Belize and Honduras but can still be dangerous at certain times. Sometimes at these resorts it is difficult if you are not accustomed to the time change and would like something to eat at an odd hour, or having your room made up daily, having hot water when needed, air conditioning, telephone service, etc. Just be ready to give up some amenities that you are used to.

Hope this helps! Cheers

Luxury can most definitely by eco-friendly... in fact, even more so in many instances as luxury travelers are well-educated and are demanding more than skin-deep luxury these days. One resort that caught my eye was in the lesser carbon-emitting flight zone of the USA. A luxury eco-lodge in the Ozark Mountains, where every single fixture and fitting is eco-friendly. From Energystar appliances, to recycled tiles, bamboo bedding, organic cotton towels, recyclable outdoor furniture and smartwood furnishings. The theme of the lodge is adventure... with a 500-mile mountain-clear lake at your disposal, 50 acres of trails, 2 championship fishing rivers and the USA's first National River - Buffalo National River for floating and hiking to waterfalls.

Check out the Post Ranch Inn in Big Sur, CA. This is one of the few destinations I've revisited. It's god's gift to the West Coast! The resort offers all the amenities of a luxury hotel and more within a natural setting overlooking the pacific ocean.

Local jurisdictions limit the amount of development within and regulate all construction so none of the newer establishments can even be seen from highway. The resort offers villas, treehouses, & suites, a full service spa, and fine-dining facilities. They also maintain their own private hiking trails for guests.

I stayed in one of their treehouses a couple of months ago and it was just amazing.
