Unforgettable Natural Phenomena Trips To Put on Your Radar for 2025

At its best, travel provides moments that remain etched in your memory for a lifetime; some of these opportunities are the natural phenomena trips available in 2025.

This could include occasions when you’ve experienced pure, unfettered peace or joy while traveling, or perhaps moments filled with the thrill of a high-octane adventure.

Natural phenomena explorations offer another avenue to create unforgettable travel memories. And thanks to the wild and wonderful beauty of this planet we call home, there is no shortage of such opportunities.

What’s more, according to travel industry insiders, 2025 is poised to be a booming year for natural phenomena trips. It’s a development that’s being driven by a variety of factors, not the least of which is the success of travel surrounding 2024’s total solar eclipse path of totality. But that’s not the only reason why globetrotters are especially focused on such special experiences this year.

“There’s a growing trend for unique and memorable experiences and a desire to be surrounded by nature,” Kendra Guild, vice president of North America for travel company Solos Holidays tells TravelPulse. “Post-Covid in particular, people have realized that life is short and is about making memories.”

Natural phenomena trips may also be uniquely soul-nourishing for travelers, Ben Bressler, founder and CEO of Natural Habitat Adventures says.

“Natural phenomena embody the grandeur and mystery of nature, something apart from the ordinary routines of our daily lives,” says Bressler.

“Our naturalist expedition leaders tell us that our guests are enthralled by wondrous experiences — they find the feeling of awe, which often accompanies witnessing natural phenomena, to be uplifting, connecting them to something greater than themselves,” adds Bressler.

Some of the most well-known natural phenomena experiences include witnessing the great migration in Africa, taking in the northern lights or viewing bioluminescent ocean waters. But those are merely a few of the remarkable experiences available to travelers.

With this year’s growing penchant for natural phenomena travel in mind, TravelPulse spoke with a variety of global tour operators about the not-to-miss trips and opportunities on offer for 2025. Here’s a closer look.

Monarch Migration, Mexico’s Central Highlands

Faced with myriad threats to their existence, including climate change and habitat loss, monarch butterflies have an especially uncertain future. That’s just one of the reasons why you might want to put Natural Habitat Adventure’s Kingdom of the Monarch itinerary on your to-do list this year.

Witnessing the annual migration of these delicate creatures to Mexico’s forested central highlands is also simply astounding.

Each fall, millions of monarchs make an extraordinary 3,000-mile flight from the northeastern United States and southeastern Canada to their ancestral breeding grounds in Mexico. Here, they spend the winter and mate before eventually taking flight on their return journey northward in March.

Observing this enormous gathering in person is a one-of-a-kind travel experience, says Nat Hab Expedition Leader and Chief Sustainability Officer Court Whelan.

“When we think of wildlife migrations, ‘charismatic megafauna’ may spring first to mind, like Africa’s annual circuit of two million wildebeest and zebra traversing the Serengeti or the 5,000-mile journey gray whales make from Alaska to Baja each winter to breed and birth their young,” Whelan tells TravelPulse. “Yet the monarch migration, while it involves far smaller creatures that weigh a mere half a gram, is no less wondrous.”

The monarchs arrive in Mexico’s central highlands like clockwork between the end of October and the first of November, right around the Day of the Dead — prompting locals who have witnessed the migration over centuries to suggest the butterflies are the returning spirits of their departed ancestors.

During this annual event, several hundred million monarchs cluster on groves of oyamel trees (a species of fir) in a compact area that’s only about 12 square miles.

“Watching the butterflies, standing in their midst, is a truly awe-inducing experience,” continues Whelan.

“When the temperatures are cool and clouds cover the sun, the butterflies cluster to stay warm, blanketing the trees like thick, rust-colored leaves,” he adds. “Only when they quiver do you realize they are living creatures. Then, when the sun comes out and the air warms, they take to the air, sometimes fluttering overhead in a veritable cloud of orange, their translucent wings backlist by the sun.”

Even more incredible, there are typically so many monarchs gathered in the region’s protected sanctuaries that visitors can hear the butterfly’s wings humming.

It’s a remarkable phenomenon that still mystifies scientists, as it’s not yet fully understood how the butterflies manage to even find the Mexican central highlands location, as they are flying here for the first time.

The migrating butterflies are born in the U.S. and Canada and have never been here before, Whelan points out. “That element alone of this natural phenomenon is amazing,” says Whelan.

Koyo Season, Japan

Japan’s Koyo season is an annual autumn event that has quickly become the country’s second most popular natural attraction behind its legendary spring Cherry Blooms. During Koyo, tree leaves turn intensely bright colors with the Japanese Maple becoming a brilliant shade of red and the Ginkgo tree transforming to a vibrant yellow. 

This special show starts off in September and peaks in November, when Kyoto and Tokyo are most vibrant.

“For the Japanese, Koyo is not just a visual phenomenon but also an opportunity for quiet contemplation and reflection, and this is something we encourage our guests to embrace also,” Kendra Guild, vice president of North America with the travel company Solos (which just expanded into the United States), tells TravelPulse.

Because of rising demand for this particular natural phenomena experience, the first November 2025 Koyo itinerary that Solos released quickly sold out. But the company recently announced a second November trip.

Travelers who take part in the multi-stop journey will be able to witness how the Koyo season impacts landscapes across Japan, from Tokyo to more rural settings such as the Bamboo Forest in Arashiyama.

Synchronous Fireflies in Southeast Asia

For those of us who grew up in certain parts of the country (or the world), fireflies are practically synonymous with summer. And witnessing their sparkle on a warm summer evening can be a magical experience that stays with you for years to come.

It’s the kind of moment that G Adventures is hoping to tap into with two of its newest itinerary offerings for 2025: Philippines Solo-ish journey and Bali Solo-ish trip. Though not labeled natural phenomena trips, both itineraries include a surprise opportunity to take in fireflies.

As G Adventures Vice President of Product, Yves Marceau, explained to TravelPulse, there’s a limited number of places in the world where you can take in the firefly phenomena and G Adventures will be taking travelers to two of them this year.

“People want to have an experience that’s a little less than just the regular kind of get on a bus and travel and see places and listen to guides talking,” Marceau said of the growing demand for natural phenomena experiences. “They want to experience the world. Natural phenomena offers a chance to experience things that maybe you have read about a child or heard about as a child.”

Bioluminescent Plankton, Costa Rica



Witnessing bioluminescent plankton is another spectacular natural phenomenon and one that’s less-experienced by travelers, say experts. This particular opportunity involves observing ocean waters that appear to be glowing thanks to the presence of microorganisms.



“Bioluminescence is best seen on dark nights, especially around a new moon,” says Jeremy Clubb, founder of Rainforest Cruises, which offers an eight-day cruise featuring the experience. “Some bays and lagoons may have more active bioluminescent plankton during certain months due to local weather patterns, but on the eastern shores of Costa Rica’s Osa Peninsula, the coast of Puerto Jiménez, and the Preciosa-Platanares Wildlife Refuge in Golfo Dulce Bay are among the few places in the world where people can observe bioluminescence all year long.”

Rainforest Cruises offers sailings designed to take in Costa Rica’s bioluminescent aboard the Kontiki Wayra – a neo-luxury vessel with a capacity of just 18 people for a more exclusive experience. The company just launched its inaugural Costa Rica sailing this January. The best time of year to see the bioluminescent waters is from April through November.

Bird Migration and Nesting Season, Tanzania

While birdwatching on vacation, otherwise known as ‘avitourism’, is not exactly a new experience, it has become increasingly popular around the world. And Tanzania, as it turns out, is home to some 1,000 bird species. Translation: It’s  a birdwatcher’s dream destination.

But more to the point of this story, while Tanzania is special at any time of year, nesting season (December through March) is a particularly memorable time to visit and take in a natural phenomena.

“December to March falls under the country’s Green Season,” David Guthrie, founder of Tanzania safari company, A Tent With A View, explains. “This is an often overlooked time to visit for classic safari-goers, but an incredibly special time for birding. This is nesting season, when many species are in full breeding plumage and are displaying and nesting.”

“Not to mention it’s also a peak time for migratory birds coming to the country and ideal conditions for bee-eaters, rollers and flycatchers, who are drawn in by the increased number of insects,” adds Guthrie.

A Tent With A View is offering an itinerary named The Ultimate Birding Safari, which takes travelers to carefully chosen parks where they will be able to take in many rarely-sighted species. The nine-day trip includes visits to three of the top birding destinations on the planet, including the world’s largest tropical lake and East Africa’s only coastal wildlife park.
