Summer only comes once a year; when your vacation rolls around, you should seek out the most unique, exciting destinations in the world. June, in particular, is one of the hottest months for festivals and music shows, not to mention that nature is in full bloom. Have you ever explored an untouched, remote jungle teeming with wildlife or gone swimming with dolphins in the ocean? If you've never combed through an ancient architectural site, this summer is when you should change that!

01Go jaguar spotting in Brazil

Pantanal offers the best opportunities for jaguar-watching around the world. Jaguars are notoriously hard to spot in the wild, but the ones in Pantanal are used to human presence. So not only will it be easy to go jaguar spotting, but it'll be entirely ethical. The world's largest tropical wetland hits a dry season in June that provides perfect conditions for sighting. Don't stop your exploration with only jaguars while you're in South America's most biodiverse destination. Join other wildlife safaris to see otters, tapirs, hyacinth macaws, toco toucans, and the famous anaconda.

Gorilla trekking is a must when visiting Uganda. The dry spell of June makes it the perfect season for getting lost in the untamed wilderness of Uganda and seeing our distant evolutionary cousins. Once you've finished your gorilla-spotting trek, there's plenty more to enjoy in Uganda. You can challenge yourself to a Nalubale river rafting journey, get involved in the local culture in the Ndere Centre, or stand right on top of the equator.

03Embrace your inner Viking in Greenland

In Greenland, you can follow the footsteps of the Vikings who discovered the new world. About a thousand years ago, the infamous Erik the Red settled Greenland after Iceland exiled him for murder. According to legend, he set out with 25 ships, but only 14 of them made it to Greenland. A notable example of historic sites is Erik the Red's estate, Brattahlíð: it's the best-preserved site on the island. There are tours available to explore Brattahlíð as well as the rest of the nearby coast. If you have time left in your trip, you can enjoy taking a hike in one of the cleanest parts of the world, visit various UNESCO sites or spend a weekend in one of the cozy villages scattered all over the country.

You can quench your thirst for beauty this June with the delightful Japanese ajisai festivals. Ajisai festivals are all over Tokyo in the middle of June. A notable example, the Bunko Ajisai Festival, starts in early June and runs until the middle of the month at Hakusan Shrine. There are 10,000 plants on show, and entrance is free. These festivals mark the height of summer rains, which help cause another beautiful natural phenomenon: swarms of fireflies. From mid-June to the end of July you can visit the Tsukiyono Firefly Village on the west side of the Jomo-Kogen station.

Barcelona is one of Europe’s most attractive destinations and is the third most visited city on the continent. For your next trip, all you have to do is find accommodation and book a trip with "Free Bike Tour Barcelona" to enjoy a unique travel experience. According to their website, "visitors to Barcelona discover so much more by bike in 3 hours than in 3 days on foot or from the seat of a tourist bus", and they're right!. Barcelona is exceptionally bike-friendly, colorful, and filled with stunning architectural masterpieces. Book early, though: the tours sell out quickly!

08Take a break in Lisbon, Portugal

If active rest is your thing, right after biking around in Spain, you should head to Lisbon. The temperatures during June are perfect for hiking in the evening without tiring yourself out too badly. After a gentle hike around the hills of Lisbon, you can take a class in Portuguese pottery painting during the day. At night, come out to play, drink, party, or try the variety of luxurious wines that Portugal has to offer.

09Roses and fire dancing in Bulgaria

You can find Bulgaria tucked away at the bottom right corner of the map of Europe, right alongside Turkey. Bulgaria is home to many festivals in June, but there are two that truly stand out. Bulgaria contributes 70% of the total world rose production every year, and much of this comes from the Rose Valley of Kazanlak. Each year, they honor the flower in their rose festival with many activities such as rose picking, the Queen Rose competition, and the fireworks show. On the 3rd day of June, you can head to one of the villages in the Strandzha region to see the ancient tradition of fire dancing. The "nestinari" honor the Sun god by dancing barefoot on burning coal. If you have the heart for it, watch: but locals advise against participation!

10Go summer skiing in Australia

If you've lived your whole life in the Northern Hemisphere, skiing in June sounds like a joke more than an actual opportunity. June skiing is one of the biggest attractions in Australia, though. The state of Victoria has a number of popular ski resorts with a multitude of slopes, ready to cater to all levels of skier. Even if you've never tried skiing before, Mt Baw Baw has a collection of classes and courses. So, if you ever have the urge to learn how to tame a snowboard or you're eager to cool down in the middle of June, book a flight to Australia.
