Summary

Mexico is a vibrant country boasting an interesting natural history, as well as some stunning scenery and fascinating culture both past and present. This tour visits central and south-western Mexico. We begin our holiday in the pre-Aztec city of Teotihuacan, enjoying this superb site, home to the third largest pyramid in the world, as well as a variety of endemic and other birdlife. Next we drive to the Oyamel Fir forests of the central Mexican state of Michoacan where the microclimate provides the perfect winter home for millions of Monarch butterflies. We will visit two of the best reserves mid-morning and watch as millions of butterflies take to the wing! After a 3-night stay in this region, we fly to Puerto Vallarta on the Pacific coast where we take to the ocean in search of Humpback Whales. Four days on the western coast allows us time to enjoy the Humpbacks and look for birds such as Boat-billed Heron and San Blas Jay before it is time to head back to Mexico City for our flights home.

Mexico is a fascinating and vibrant country: a colourful land steeped in history, myth and legend. This was the home of the ancient Aztec, Toltec and Maya civilisations, whose great pyramids rival those of Egypt, and landfall for the first of the Spanish Conquistadors as they searched for the fabled Cities of Gold. Today, Mexico is a modern, vibrant and welcoming country, full of natural history, scenic and cultural contrasts. It is also the stage for one of the most remarkable sights in the natural world, the winter gatherings of millions of Monarch butterflies.

Whilst south-eastern Mexico is clothed in thick tropical forests, in the north and west hot cactus deserts dominate. In between these extremes lie the cool Oyamel Fir forests of the central Mexican state of Michoacán. Here, the temperature, humidity and high altitude combine to create the perfect winter microclimate for millions of Monarch butterflies from the US and Canada which migrate south into Mexico every autumn to escape the cold further north. These are the third or fourth generations of butterflies that left Michoacán the previous spring and, to this day, little is known about how these delicate creatures navigate and how they find these small pockets of forest hundreds, if not thousands, of miles south from where they first emerged as adults.

As spectacular as the Monarch gatherings undoubtedly are, Mexico has many other wildlife facets to enjoy. During the same months that the butterflies gather in Michoacán, Humpback Whales congregate in Banderas Bay off Mexico’s Pacific coast, and numerous resident and wintering birds — including 25 Mexican endemics — can be found in the nearby wetlands, mangroves and forests. Although our tour takes in all these highlights, it begins with a flight to Mexico City from where we transfer to our first overnight stop at the pre-Aztec city of Teotihuacán (‘Place of the Gods’). We will explore the site the following morning, enjoying such birds as Vermillion Flycatcher, Canyon Towhee and Say’s Phoebe beneath the imposing triangle of the huge ‘Pyramid of the Sun’, the third largest pyramid in the world!

Next we drive west into the forested hills of Michoacán for three nights in Valle de Bravo. From here we will visit two Monarch reserves. We plan on arriving mid-morning, at a time when the sun has warmed the forests sufficiently for the butterflies to start taking flight. It is a breathtaking spectacle. The trees here can become so laden with Monarchs that branches bend under their weight and, once the butterflies take to the air, the forest fills with the delicate sound of a million fluttering wings, turning the air into a whirlwind of orange and black! If we can drag our eyes away from the mesmerising clouds of butterflies for a few moments, we are also sure to find an interesting variety of birds such as Red Warbler and Slate-throated Redstart.

For the second part of our holiday, we take a short flight to Puerto Vallarta on the Pacific coast. Once here, we will need to readjust our eyes from watching the small and delicate to the huge and mighty, for the next two mornings we take to the ocean in search of Humpback Whales. Humpbacks are one of the most entertaining whales to watch and during our time on the water we hope to witness a variety of behaviours, including spy-hopping, tail-lobbing and, for the fortunate, perhaps a full breach, whereby the whale launches itself fully out of the water before falling back with a resounding splash!

Moving on, we turn our attention to the excellent avifauna of Mexico’s Pacific coast, and drive north to the fishing village of San Blas. Mexico is home to nearly 1,100 species of birds, 10% of which are endemic. The estuaries, lagoons, mangroves and forests around San Blas attract a wide variety of these, including Boat-billed Heron, Golden-cheeked Woodpecker, Ivory-billed Woodcreeper, Citreoline Trogon and San Blas Jay.

Finally, after two days spent enjoying the birdlife of western Mexico, it will be time to return to Puerto Vallarta for our short flight to Mexico City, where we connect to our onward flight home.

The variety of experiences: pyramids, butterflies, whales and birds. Not too much of any one topic. More specifically: Vermillion Flycatchers, the first Monarch site, whale-watching and alfresco breakfast birding on day 8 overlooking the Pacific!

Good varied content to see a range of species, in different landscapes and habitats. The travel also enabled us to see towns and villages, for an overview of the country. The Whale-watching trips were superb and memorable, also visiting the Monarch butterfly sites and learning about their incredible life-cycles. Lastly the amazing boat trip through the mangrove swamps at San Blas was also a highlight, an incredible experience! Martin was expert on bird identification and good company. Michael was also very knowledgeable and helpful, and he gave us very good background information on the whale-watching trips. Karel was enthusiastic and informative and took us to the best places to see wildlife and to have excellent meals!

A most enjoyable guided group trip to Mexico. We visited ancient pyramids, trekked up to see amazing Monarch butterfly sites, used boats to find singing Humpback Whales and got up early to find beautiful birds. Great organisation in advance, excellent choice of venues, and expert and caring leaders and local guides. Transport during the trip included aircraft, minibuses, jeeps, boats and even horses - and they adapted very well when local protests closed roads in one of our resorts.

Such a wide variety of flora and fauna seen in a diverse selection of habitats. Always lots to see. I loved the places we were taken, and we were given plenty of time to look around and spot wildlife. Martin met us at Heathrow and I instantly felt safe and secure with him guiding us. Martin, Michael and Karel were all patient, knowledgeable and approachable. They shared their enthusiasm for the birds and wildlife, and also kept us safe, well fed and watered throughout the trip. Martins anecdotes kept us laughing and we gelled as a group very well as a result. The two highlights were watching whales breach next to our boat, and watching the thousands of Monarch butterflies flying around us. I also loved the boat ride into the mangroves.

Wildlife tour with Naturetrek to see Monarch Butterflies, Humpback Whales, birds and ancient pyramids. Dazzling programme with full days, superb guiding, good hotels and local freshly cooked food. Friendly group with a mixture of interests. In fact a really fantastic experience. Thorough pre-travel service, good updates and good advice and helpful and efficient service throughout. Excellent guides made sure that we saw absolutely everything and had such detailed knowledge of the birds and whales in particular.

Non-stop pleasure from start to finish. This is a 'MUST DO' for anyone interested in wildlife. I have always wanted to see a Hummingbird, dream fulfilled! The breaching Humpbacks are incredible and will always stay in mind too. From first booking until sadly saying farewell back at Heathrow, the experience was a perfect example of how a much longed for trip should flow. The pre-departure document covered every detail I needed to know about, the itinerary was thoughtfully compiled and carried out by leaders who clearly know their stuff. The accommodation was always just where you would have chosen yourself. Seriously cannot fault any aspect of the holiday, it'll stay with me forever. Naturetrek is a small company with a big reputation for delivering outstanding holidays. This is my forth trip with them and as always the brochure summary is just what you get. Long may they continue!

I’d always wanted to see the Monarch migration to the forests of Mexico and couldn’t believe my luck when I found a tour which not only took in the Monarchs but also Humpback Whales, one of my other passions. The whole trip fulfilled all my hopes and expectations in seeing not only the Monarchs and Humpbacks but also lots of other butterflies as well as birds. Everything was dealt with promptly and thoroughly and all my questions answered. Everyone was extremely helpful and I can highly recommend Naturetrek.

We chose this holiday because of its mix of seeing a range of wildlife, as well as its archaeological interest. We were not disappointed. We got a sense of what a vast and varied country Mexico is. We experienced high plateau, forested mountains, the Pacific coast, mangrove waterways and coastal and mountain villages.

My husband and I love nature, and to be able to go on this Naturtrek holiday to Mexico was a dream come true. My husband loves butterflies so we were in awe of the annual migration of Monarch butterflies. To see humpback whales has always been on my bucket list, and our boat trips out fulfilled all my dreams. I can now die happy. These two were the highlights of our holiday, but interspersed with these there was ample opportunities to appreciate the huge variety of birds, a trip into the mangroves to see crocodiles etc. It is a holiday neither of us will forget.

The holiday was targeted at seeing the Monarch butterflies in their winter roost in Mexico - up at over 10,000 feet above sea level. It was quite an expedition to get there, but the sight was phenomenal. We will never forget the sight of so many butterflies, perched on branches in such numbers that the branches bent down under the weight of so many insects. Then it was off to the Pacific where the Humpback Whales were giving birth in the warmer waters there. A totally different scale, from tiny insects to huge whales. Then it was on to another site, and a trip into a Mangrove swamp in late afternoon with so many interesting birds beginning to roost up for the night, and a few crocodiles to be seen, followed by a trip back after dusk. Another memorable event. Lastly there were a few days for birdwatching or butterfly spotting with an expert with us to help find the unusual. We have lots of photos and lots of memories of a wonderful holiday, and will be travelling with Naturetrek again in the near future, as we have found their holidays reliably full of wonderful wildlife, and we are always escorted by experts who add so much value to the trips.
