8 of the World's Best National Parks You Must Visit

The world's best national parks are the closest thing we have to a shared inheritance - places a country looked at once and decided to never build on. What makes them so good for travellers is that somebody has already done the hard work: the trails are marked, the wildlife is protected, and the most extraordinary viewpoints are usually a signposted walk from a car park. From geothermal basins in Wyoming to komodo dragons in the Lesser Sunda Islands, these eight parks span five continents and every kind of wild. Here's what to see in each, when to go, and the detail that makes it worth the flight.

Yellowstone National Park, USA: The World's First National Park

Yellowstone was the planet's first national park back in 1872, and it still feels faintly unbelievable - roughly half of all the geysers on Earth sit inside its 2.2 million acres. Everyone comes for Old Faithful, but the Grand Prismatic Spring is the one that will genuinely stop you mid-sentence: a 110-metre-wide pool ringed with orange and jade bacterial mats, best seen from the Fairy Falls overlook trail rather than the boardwalk. The Lamar Valley at dawn is North America's Serengeti, with bison herds, pronghorn, and a decent chance of wolves if you bring binoculars and patience. The best time to visit is September, when the summer crowds thin out and the elk rut fills the valleys with bugling.

Torres del Paine, Chile: Patagonia's Granite Cathedral

Torres del Paine is the reason people cross the world for Patagonia - three sheer granite towers rising out of the Chilean steppe like something drawn rather than eroded. Most visitors walk the W Trek, a four-to-five day route that links the base of the towers, the French Valley, and the electric-blue Grey Glacier, staying in refugios along the way. If you only have a day, hike to Mirador Las Torres at sunrise, when the peaks briefly glow pink before the wind picks up. Book refugios and campsites months ahead for the November-to-March window, and pack for four seasons in an afternoon, because Patagonian weather has no interest in your forecast app.

Sagarmatha National Park, Nepal: Trekking in the Shadow of Everest

Sagarmatha is the park that contains Everest, and you don't need mountaineering skills to experience it - the Everest Base Camp trek is a walking route, not a climb. Flying into Lukla's cliff-edge airstrip and following the Dudh Koshi valley up through Namche Bazaar takes you past Tengboche Monastery, where monks chant at 3,867 metres with Ama Dablam framed in the doorway. Kala Patthar, at 5,545 metres, delivers the classic sunrise view of Everest itself, and it's the highest most trekkers will ever stand. Go in October and November for stable skies and clear peaks, and build in acclimatisation days - altitude, not fitness, is what turns people back.

Kruger National Park, South Africa: Big Five on Your Own Terms

Kruger is roughly the size of Wales and the most accessible big-game park in Africa, largely because you can drive it yourself in a hire car. That self-drive freedom is the hidden gem here: for the price of a park entry fee you can spend a day parked at a waterhole in the Satara region watching lions, elephants, and buffalo cycle through. The Big Five - lion, leopard, rhino, elephant, buffalo - all live here, and the southern camps like Lower Sabie and Skukuza give the highest sighting density if your time is short. The best time to visit is the dry winter months of June to September, when thin bush and shrinking water sources push animals into the open.

Jiuzhaigou Valley, China: Impossibly Blue Lakes and Autumn Colour

Jiuzhaigou, in northern Sichuan, looks colour-graded and isn't - the mineral-rich water in its terraced lakes produces turquoise, cobalt, and emerald so saturated that photos get accused of editing. The Five Flower Lake, with ancient fallen trunks visible metres beneath the surface, is the signature stop, and Nuorilang Waterfall spreads 320 metres across a travertine shelf. A boardwalk system runs the length of the Y-shaped valley with shuttle buses between sections, so you can walk as much or as little as you like. Visit in mid-October, when the surrounding forest turns gold and red and doubles the intensity of everything reflected in the water.

Tongariro National Park, New Zealand: A Volcanic Day Hike Like No Other

Tongariro was the fourth national park established anywhere on Earth, gifted to the nation by Ngāti Tūwharetoa chief Te Heuheu Tūkino IV, and it holds dual UNESCO status for both nature and Māori cultural significance. The Tongariro Alpine Crossing is widely called the best day hike in New Zealand: 19.4 kilometres over a lava-scarred saddle, past the steaming Red Crater and the acid-bright Emerald Lakes. Mount Ngauruhoe looms over the route and doubled as Mount Doom on screen, which explains a fair share of the traffic. Book the mandatory shuttle transport in advance, start early, and check the forecast obsessively - it's exposed alpine terrain that turns hostile fast.

Denali National Park, Alaska: Six Million Acres and One Road

Denali protects six million acres of subarctic wilderness with a single 92-mile road running into it, and private vehicles are only allowed on the first 15 miles. That constraint is the whole point: you take a park bus, and the lack of traffic means grizzlies, caribou, moose, and Dall sheep behave like you're not there. North America's highest peak, Denali itself at 6,190 metres, is famously shy - only around 30% of visitors see the summit clear of cloud, so give yourself several days. Come between June and early September, and consider a flightseeing trip with a glacier landing, which is the single best money you'll spend in Alaska.

Komodo National Park, Indonesia: Dragons, Pink Sand, and Manta Rays

Komodo is the only place on the planet where you can walk with wild komodo dragons, three-metre monitor lizards that exist nowhere else, on guided ranger walks across Rinca and Komodo islands. Above water, the climb up Padar Island at sunrise gives the view that sells the whole region - three crescent bays fanning out below in different shades. Below it, Manta Point delivers reliable encounters with manta rays, and the diving here ranks among the best in Indonesia. Base yourself in Labuan Bajo on Flores, go between April and June or September and November to dodge peak crowds and rough seas, and don't skip the pink sand of Pantai Merah.
