I mean just look at some of the gorgeous locations they chose to build at. White sand beaches, incredible turquoise water, cliff-side locations to enjoy the tropical breezes – I mean these guys definitely knew what they were doing in picking out some prime beachfront locations.

If you don’t believe it, just check out a few of the pictures below that depict some of the Mayan ruins at Tulum in Mexico’s Yucatan Peninsula. Now imagine standing on the bluffs, enjoying a spectacular view looking out over an emerald Caribbean Sea.  

It just doesn’t get much better than that!

Around 1000 A.D. Chichen Itza in Yucatan was the center of the Mayan civilization, which was spread throughout the Yucatan Peninsula, through Belize and Guatamala, and on to the edges of Honduras and El Salvador.

Today the Maya number around five million and live mostly in the Yucatan Peninsula and the highlands of Guatemala. As they did over a thousand years ago, most live in villages and make their living from the land.

Our modern cities are primarily centers for commerce which is completely different from the purpose of the Mayan stone city remains we see today. For the ancient Maya, these were principally ceremonial sites and gathering places where they came for spiritual reasons.

During the early 1500’s the Spanish were determined to systematically destroy the Mayan civilization. One of the world’s greatest cultural crimes was their destruction of all the wriitten records they came across.

As for the people themselves, those not killed in battle, were mostly decimated by diseases carried to the “New World” from the “old”. Today the magnificent stone cities lie abandoned and in ruins once more.

Tulum or the “Walled City” was built by the ancient Maya on a cliff overlooking the Caribbean. One of the most visited archaeological sites in Mexico, it was occupied for over 300 years, from around 1200 A.D. until after the Spanish conquest.

Located at a convergence of both land and sea trade routes, Tulum was a major link in an extensive trade network. Artifacts found in or near the site indicate Mayan commerce ranged from Central Mexico to Central America and all points between.

The Castillo, sometimes referred to as the lighthouse, is the tallest building at Tulum and the most famous. It stands on the bluff, commanding a view of the ocean and coast for several miles in both directions.

Until the late 20th century when tourists became too numerous, the local Maya continued visiting the temples to burn incense and pray.

There is no way to gain a real appreciation of the Mayan culture without visiting some of these ruins that have been abandoned to the elements. There are hotels to be found in the area, plus the Tulum ruins are only a two hour drive south of the popular beach resort of Cancun, which makes for a pleasant day trip.

To this end they fund scientific field research and provide ways for regular folks – like non-scientists, to act as volunteers on projects around the world. Besides traveling to exotic locations, you get the opportunity to participate in these projects and maybe even learn a thing or two.

There are expeditions to a variety of locations, and depending on your interest will hold differing appeals. The ones I like are those involving the oceans and opportunities to dive as part of the work.

Below are some sample locations and a brief synopsis of what volunteers can expect:

First are the Coral Reefs of Thailand:

In the Gulf of Thailand and Andaman Sea, Thailand’s coral reefs are some of the most magnificent and diverse ecosystems on Earth. Like many of the world’s reef systems, Thailand’s reefs are facing the pressures of overfishing and destructive fishing practices, as well as the threats posed by global warming and coral diseases. Scientists from Reef Check are joining forces with Earthwatch to survey Thailand’s resplendent coral reefs and monitor the effects of marine protected areas as well as recovery from the 2004 tsunami. With this information, agencies and local communities can better manage and conserve these beautiful reefs.

Perhaps the south Pacific is more to your liking. Here’s a chance to spend a couple weeks Diving the WWII Wrecks of Truk Lagoon:

Now part of the Federated States of Micronesia — Truk (a.k.a. Chuuk) was an Imperial Japanese Navy base during World War II. Considered second only to Pearl Harbor in strength, the U.S. saw this base as a major threat and in February 1944 began Operation Hailstone, a 2-day intense aerial bombing campaign that continued in various forms until the war’s end. More than 50 naval and merchant ships were sunk in Truk Lagoon, along with up to 100 aircraft, with many intact, having been protected by the surrounding barrier reef. Maritime archaeologist Bill Jeffery, materials scientist Dr. Ian Macleod, and marine ecologist Maria Beger aim to document and help protect Truk Lagoon’s rich historic and biological heritage.

Or maybe the Belize Regional Initiative:

Be part of a collaborative effort to conserve an entire ecosystem. Based on remote islands scattered along the world’s second largest barrier reef, our Belize projects offer snorkeling, diving, and shore-based experiences. Surrounded by one of Earth’s largest barrier reefs, Belize is becoming a popular destination. But despite the designation of its waters as protected Marine Reserves, coastal development, overfishing, and tourism threaten the biodiversity of this tiny nation. We offer the chance to study and protect the life that depends on this reef. Whether your team is based at our remote Living Reef Center or at a beachside hotel, you can experience Belize in a unique way and be part of a group of projects working to help this country strike a balance between economic growth and ecosystem health.

Volunteers are responsible for the cost of getting to the assignment location plus a contribution amount that covers meals and lodging, plus other associated costs. This expense is far less than a typical vacation in the same area, and there is usually enough free time to check out the locale. Learn more about Earthwatch Institute and upcoming projects here.
