Don't miss this opportunity to explore the celestial prowess and dazzling art and architecture of the ancient Maya on Sky & Telescope’s exclusive 10-day tour to witness the annular solar eclipse on October 14, 2023.

In ancient cultures, eclipses of the Sun were seen as powerful portents for both good and (often) evil. But few of these civilizations attained the celestial sophistication of the Maya in Mesoamerica. Their astronomer-priests looked to the heavens for guidance and developed the most intricate and accurate calendar in the ancient world. Ceremonial buildings were precisely aligned with compass directions, with some built to create fleeting solar alignments at the equinoxes.

Immerse yourself in Maya culture — marveling at both its celestial prowess and its dazzling art and architecture — on Sky & Telescope’s exclusive 10-day tour across the Yucatán Peninsula. And, invoking the spirit of the great Maya skywatchers, we’ll gather at an exclusive viewing site on October 14, 2023, to witness an annular (ring) eclipse of the Sun.

If you enjoy touring with smaller-size groups, this opportunity is for you! Our travel partner for this expedition is Royal Adventures (CST#2009579-40), a company that specializes in tours to Latin America and prides itself on providing travel experiences of unmatched quality. Our tour is limited to a maximum of 20, and you’ll be accompanied by expert local guides as well as representatives from both Sky & Telescope and Royal Adventures.

Your adventure begins in colorful Cancún on October 6th. Then make your way across the peninsula to visit the most revered and historic Maya sites — Chichén Itzá (and its famed El Caracol Observatory), Ek Balam, Uxmal, Kabah, and Edzná — before visiting the vibrant capital city of Mérida and the historic coastal town of Campeche. You’ll even get the chance to swim in one of the region’s cenotes, limestone sinkholes created in the aftermath of the asteroidal collision that devasted the Gulf of Mexico 66 million years ago and wiped out most of Earth’s life forms. Then fly home on October 15th.

Highlights of the Yucatán Annular Eclipse 2023 Adventure

Sky & Telescope’s Eclipse-Viewing Site
Our carefully chosen site for witnessing the annular eclipse represents a balance of excellent geometric placement (19°50.9'N, 90°32.3'W), optimal climatology, and the comfort of participants. You’ll view the entire event from the comfortable grounds of Gamma Campeche Malecón, which overlooks the Gulf of Mexico and just steps from your room. Here sea-breeze winds give a sunnier climate than elsewhere over the peninsula, with the best odds anywhere on the Yucatán Peninsula for clear skies on eclipse day. You’ll watch a smaller-than-usual Moon slide across the Sun over 3½ hours and cover 95% of it, leaving a brilliant ring — or annulus — in the sky. From our location, this “ring of fire” will be high up (altitude 61°) and last for 4 minutes 32 seconds, with the eclipse’s midpoint at 12:25 p.m.

El Castillo pyramid at Chichén Itzá

Chichén Itzá
The most famous and most restored of the Maya sites and one of the new Seven Wonders of the World thrived from around 600 to 1200 AD.  Its Maya name means “At the mouth of the well of the Itza”. Soaring above the site is the Temple of Kukulcán, also known as El Castillo, a massive step pyramid. Nearby is El Caracol, whose rounded center may be reminiscent of a telescope’s dome but is actually the ruins of a cylindrical structure. Still, there’s ample evidence that it served as an astronomical observatory. You can explore the site’s graphic stone carvings that survive at structures like the ball court, Temple of the Warriors, and the Wall of the Skulls. 

The majestic Pyramid of the Magician dominates the ancient ruins of Uxmal

Uxmal and Edzná
The Maya were expert sky-watchers, careful observers of the motions of the celestial bodies. Their fascination with astronomy is evident in the grand architecture at sites such as Chichén Itzá, Uxmal (shown above), and Edzná, and many more. At many of these sites, hieroglyphic carvings refer to celestial bodies and cycles. Often, the buildings they adorn have been built to align with significant cyclical astronomical events—solstices, equinoxes, the moon, the stars, or the rise of planets.

The Museum of the Maya World in Mérida, Mexico

Museum of the Maya World
This is a world-class museum that celebrates Maya culture. Its contemporary building design evokes the form of a ceiba, a tree sacred to the Maya. They believed it connected the living with the underworld below and the heaven above. The highlight of the museum’s natural-history section is the exhibit on the Chic’xulub impact — a history-altering (and dinosaur-dooming) event that occurred when a 6-mile-wide asteroid slammed into our planet about 66 million years ago. The resulting crater, 120 miles across, led to the creation of a ring of cenotes (freshwater sinkholes) that abound in the Yucatán today.

Day 1, October 6 — Arrive in Cancún
After flying from your home to Cancún, México, you’ll be transferred to our hotel close to the airport. Relax until early evening, when you’ll meet other tour participants in the hotel’s reception area and hear a briefing on tomorrow's departure and activities.  Courtyard Marriott

Day 2, October 7 — Cobá / Chichén Itzá
We’ll depart after breakfast and head to the archaeological Maya site of Cobá, which is surrounded by luxuriant vegetation. After the visit, you’ll have lunch and then transfer to your hotel at Chichén Itzá, one of the finest Maya archaeological sites in the northern Yucatán Peninsula. Relax at the hotel upon arrival, then join the group for a welcome dinner with cocktails.   Hotel Mayaland (B, L, D)

Day 3, October 8 — Chichén Itzá
Enjoy a private sunrise tour of Chichén Itzá before it opens to the public. The site contains massive structures including the immense El Castillo pyramid, serpent-adorned balustrades, columns, and ominous skull racks. Built sometime in the 7th century, El Castillo had an astronomical purpose and is actually a symbolic representation of the Maya calendar. For example, the number of steps in all of the monumental stairways adds up to 365. Another astronomical structure, El Caracol (also known as the Observatory) bears a striking resemblance to modern astronomical observatories. Its windows and doorways are specifically aligned with the movements of the Sun, stars, and planets, particularly Venus. Chichén Itzá is also home to the largest known Maya ballcort.  Hotel Mayaland (B, L, D)

Day 4, October 9 — Ek Balam / Cenote Maya
This morning visit the Late Classical period Maya ruins of Ek Balam, which means “black jaguar.” What makes this site unique is the shape of the main pyramid and the fact you can climb to its top. In the afternoon enjoy a swim in a nearby freshwater cenote (limestone sinkhole). A ring of cenotes was formed across the Yucatán Peninsula following a colossal asteroid impact 66 million years ago that triggered catastrophic destruction during the time of the dinosaurs.  Hotel Mayaland (B, L, D)

Day 5, October 10 — Mérida
This morning travel to Mérida, Yucatán’s capital and largest city. Enjoy a tour of the city’s beautiful government buildings, monuments, and shady tree-lined plazas. Visit Gran Museo del Mundo Maya (Museum of the Maya World) for a lecture on the Chic’xulub crater left by the million-megaton impact that devastated the Gulf of Mexico and caused a worldwide species extinction 66 million years ago.  Then settle into our comfortable hotel in Mérida near plazas and historic buildings. Hilton Casa Mercedes (B, L, D)

Day 6, October 11 — Mérida / Uxmal / Kabah
This morning travel to Uxmal — arguably the most elegant Maya site, with its graceful architecture, symmetry, and grandeur. Uxmal is considered the finest and most extensively excavated example of Puuc architecture. This is the area that Stephens and Catherwood visited in 1840 and wrote about extensively in Incidents of Travel in the Yucatán Peninsula. In the afternoon, we drive to the nearby site of Kabah, the second largest Maya ruin in the Puuc region. Kabah is renowned for its “Palace of the Chaac Masks,” an especially beautiful ornate example of the Puuc style. Hilton Casa Mercedes (B, L, D)

Day 7, October 12 — Mérida / Campeche
This morning we’ll depart for the port city of Campeche on the Gulf of México, a UNESCO World Heritage Site, known for its preserved baroque colonial buildings, military architecture, and walled historic district. In response to decades of pirate and buccaneer attacks, the city was fortified in the 17th century, and two hilltop fortresses are now museums. The meticulously restored historic center of Campeche is a colonial time warp with buildings restored to pristine pastel perfection. Learn about the city’s fascinating history and enjoy a tour of the Fortress of San Miguel with its commanding views of the Bay of Campeche. The fort houses the Campeche Archaeological Museum with artifacts from local Maya sites.  Gamma Campeche Malecón (B, L, D)

Day 8, October 13 — Campeche / Edzná
Today we’ll travel to Edzná, a site that offers a smorgasbord of Maya architectural styles. Later enjoy time at leisure to explore Campeche on your own. You may wander the old city walls, learn about Campeche’s history at the Museo de la Ciudad, or explore modern street art.  Restaurants and cafes abound. Gamma Campeche Malecón (B, L)

Day 9, October 14 — Annular Solar Eclipse!
Today is dedicated to viewing the eclipse from the relaxed comfort of Gamma Campeche Malecón or from the beach overlooking the Gulf of Mexico (just steps away). We’ll enjoy a group lunch before the eclipse, then gather after its conclusion for a celebratory farewell dinner with wine and beer. Gamma Campeche Malecón (B, L, D)
