There's something genuinely restorative about stepping into a protected wilderness, big skies, quiet trails, and landscapes that don't care what's trending online. More than a billion people are expected to visit protected natural areas globally this year, a reminder that national parks have moved from the edges of travel planning to genuinely center stage. Across the United States, United Kingdom, and Australia, three countries with very different landscapes and very different national park systems, there's an extraordinary range of protected wilderness worth building a trip around.
This guide covers the best national parks to visit in each of these three countries, along with practical tips for planning a trip that respects both the landscape and the growing pressures these protected spaces face.
National Parks by the Numbers
Each of these three countries approaches national parks quite differently. The United States has 63 designated national parks, plus roughly 400 additional sites managed by the National Park Service. The UK has 15 national parks spread across England, Scotland, and Wales, each protecting inhabited countryside where people continue to live and farm alongside conservation efforts. Australia, meanwhile, holds the global record with more than 600 national parks, reflecting both its vast landmass and a long-standing conservation ethic.
Best National Parks in the USA
Yellowstone National Park
Even setting aside its distinction as America's first national park, Yellowstone stands entirely on its own merits. Spanning 2.2 million acres across Wyoming, Montana, and Idaho, it holds roughly half the world's active geysers, including the famous Old Faithful, alongside vast lakes, dramatic hot springs, and bison-filled valleys. Wolf populations here are genuinely thriving in recent years, a conservation success story that's also spurred real economic benefit for small towns surrounding the park.
Best time to visit: May or October, which balance manageable crowds with reasonable weather, avoiding the peak summer rush.
Glacier National Park
Spanning three mountain ranges and more than 700 lakes across northwest Montana, Glacier National Park offers some of the most dramatic alpine scenery in the country. Don't miss the scenic Going-to-the-Sun Road (open seasonally) or a visit to Waterton-Glacier International Peace Park, a UNESCO World Heritage Site straddling the Canadian border. Free ranger-led activities, including guided hikes and stargazing events, make this a genuinely accessible park for visitors of all experience levels.
Mesa Verde National Park
For travelers drawn to cultural and historical significance alongside natural beauty, Mesa Verde in southwestern Colorado houses nearly 5,000 well-preserved archaeological sites from the Ancestral Pueblo people, including Cliff Palace, the largest cliff dwelling in North America, with 150 rooms carved from sandstone. Guided tours to enter the dwellings run between May and October; visiting in the off-season still allows for a scenic drive along the 6-mile Mesa Top Loop Road, passing a dozen significant sites.
Denali National Park
For travelers seeking genuine solitude, Denali's ongoing road closure has created an unexpected upside: visitors arriving by air to the park's remote backcountry lodges experience a level of wildness and isolation that's become genuinely rare in America's more heavily visited parks.
Yosemite, Zion, Bryce Canyon, and the Grand Canyon
Rounding out the American Southwest and California's iconic landscapes, Yosemite National Park offers towering granite monoliths, dramatic waterfalls, and ancient giant sequoias in a lush valley setting. Zion and Bryce Canyon National Parks in Utah showcase dramatically different desert terrain, from Zion's sheer sandstone canyons to Bryce's otherworldly hoodoo rock formations. And the Grand Canyon remains one of the most awe-inspiring natural wonders on the planet, offering viewpoints and hiking experiences suited to virtually any fitness level.
Best National Parks in the UK
The Lake District
Widely considered the UK's most iconic national park, the Lake District delivers a genuine "wow" moment on nearly every visit, dramatic mountain peaks, sweeping valleys, and lakes so still they resemble glass. The scenery shifts remarkably quickly here: a peaceful lakeside stroll can lead directly into a view of England's highest peaks, including Scafell Pike and Helvellyn. It's the UK's most searched national park, and its charming villages, offering warm Cumbrian hospitality, cozy pubs, and a genuinely relaxed pace, make it just as appealing for a gentle break as for a serious hiking trip. The Lake District has also become the UK's best-equipped park for electric vehicle charging, with 18 charge points across 8 car parks, part of the park authority's goal of reaching net zero by 2037.
Snowdonia (Eryri)
Located in North Wales, Snowdonia, known in Welsh as Eryri, is defined by its majestic mountains, including Mount Snowdon (Yr Wyddfa) itself, which can be summited on foot or, remarkably, reached by train, making it one of the most accessible major peaks in Britain for families and less experienced hikers. Beyond its mountains, the park offers serene lakes, enchanting valleys, waterfalls, ancient castles, and a rich Welsh cultural heritage that blends naturally with the landscape. Snowdonia also offers genuine beach access along its coastline and skiing opportunities, giving it a broader range of activities than some of its national park counterparts.
The Peak District
As Britain's original national park, established in 1951, the Peak District combines rugged, rocky moorlands with grassy limestone dales, delivering some of the country's best walking, cycling, and world-class rock climbing. Mam Tor stands out as its most popular point of interest, a genuinely rewarding hike with stunning panoramic views, alongside cultural attractions like Chatsworth House and the historic market town of Bakewell. The park's numerous caverns, including Blue John Cavern and Speedwell Cavern, offer a fascinating glimpse into the region's geological history. Its proximity to Manchester and Sheffield makes it one of the more accessible UK parks for a day trip or weekend visit.
Pembrokeshire Coast
As the only national park in Britain defined primarily by its coastline, Pembrokeshire Coast in west Wales offers dramatic cliffs, hidden coves, golden beaches, sea arches, and puffin-spotted islands just offshore. The 186-mile Pembrokeshire Coast Path is the park's signature draw, with nearly every section delivering striking views over the Atlantic, along with genuine opportunities to spot seals, dolphins, and basking sharks along the water.
The Cairngorms and Loch Lomond
In Scotland, the Cairngorms National Park offers a genuine sense of space and remoteness, an ideal setting to properly disconnect from everyday noise, though visitors should pack for genuinely unpredictable weather, sunshine, wind, and rain can all show up within a single hour. Loch Lomond and the Trossachs National Park, meanwhile, combines mountains and water with activities ranging from hiking and cycling to jet skiing on the loch itself, and standout spots like Glencoe showcase steep slopes tumbling dramatically down to deep, still waters.
Dartmoor, Exmoor, and Beyond
Rounding out England's ten national parks, Dartmoor offers vast heather-covered moors, wooded valleys, and quaint medieval villages populated by wild ponies, while Exmoor combines expansive moorland, woodland valleys, and dramatic coastline into a firm favorite among serious walkers. Northumberland National Park, England's least populated, offers some of the darkest skies in the country, making it an excellent choice for stargazers seeking genuine solitude.
Best National Parks in Australia
Kakadu National Park
With more national parks than any other country on earth, choosing a standout in Australia is genuinely difficult, but Kakadu consistently ranks near the very top. This five-million-acre, deeply biodiverse park in the country's tropical north features expansive landscapes, towering waterfalls, and an extraordinary range of plant and wildlife species. Fly into Darwin International Airport and take a scenic three-hour road trip southeast to reach the park's most striking landscapes.
The Great Barrier Reef Marine Park
Technically a marine park rather than a traditional terrestrial national park, the Great Barrier Reef Marine Park protects the world's most extensive coral reef system, a UNESCO World Heritage Site stretching over 344,400 square kilometers along Australia's northeastern coast. Snorkel among vibrant coral, swim alongside sea turtles and manta rays, and experience one of the most significant marine ecosystems on the planet. Most tours include a mandatory Environmental Management Charge (the "Reef Tax," currently around USD 5.20 per person per day) that directly supports the reef's ongoing management and conservation.
Uluru–Kata Tjuta National Park
Home to Australia's most iconic natural landmark, Uluru–Kata Tjuta National Park in the Red Centre offers a profound cultural and spiritual dimension alongside its striking desert scenery. Recently featured among National Geographic's best places to travel, it remains one of the most significant sites for understanding Aboriginal culture and connection to land, alongside genuinely awe-inspiring sunrise and sunset viewing of the monolith itself.
Practical Tips for Visiting National Parks Responsibly
With visitor numbers climbing across all three countries, a few practical habits help protect these landscapes while still delivering a genuinely great trip.
Book well in advance for popular parks and peak seasons. Both UK summer school holidays and U.S. peak season (typically June through August) bring higher prices and limited accommodation availability, particularly within or immediately adjacent to the most popular parks.
Consider shoulder-season visits. Visiting Yellowstone in May or October, for example, offers a meaningfully better balance of manageable crowds and reasonable weather compared to peak summer months.
Check entry fees and permit requirements ahead of time. Many parks, from Yellowstone's per-vehicle entrance fee to the Great Barrier Reef's daily conservation charge, have specific costs and, in some cases, advance booking requirements that are easy to miss if you don't check ahead.
Bring a vehicle where necessary, and check public transit options where available. Parks like Snowdonia and the Lake District have limited but genuinely useful public transit options during peak season, while many U.S. and Australian parks essentially require a car to reach most points of interest.
Respect wildlife and stay on marked trails. As visitor numbers rise globally, trail erosion and wildlife behavior changes are becoming genuine concerns even in well-managed parks. Staying on designated paths and maintaining safe wildlife distances helps preserve these landscapes for future visitors.
Pack for genuinely unpredictable weather, particularly in the UK's mountainous parks, where conditions can shift dramatically within a single day regardless of season.
Choosing the Right Park for Your Trip
A few practical questions can help narrow your choice across these three countries:
Do you want dramatic geothermal features or alpine scenery? Yellowstone leads for geysers and hot springs, while Glacier and the Cairngorms offer more classic alpine mountain landscapes.
Are you drawn to cultural and historical depth alongside nature? Mesa Verde and Uluru–Kata Tjuta both combine extraordinary natural beauty with deep cultural and historical significance.
Do you want coastal scenery specifically? Pembrokeshire Coast in the UK and the Great Barrier Reef Marine Park in Australia both center their appeal directly on coastline and marine environments.
How accessible do you need the park to be? Snowdonia's train to the summit of Mount Snowdon and the Peak District's proximity to Manchester and Sheffield make both genuinely accessible for less experienced hikers or shorter trips, while parks like Denali or Kakadu reward a more significant time and logistics investment.
Final Thoughts
Whether you're drawn to Yellowstone's geysers, the Lake District's glassy lakes and fells, or Kakadu's tropical biodiversity, the best national parks across the USA, UK, and Australia offer some of the most genuinely restorative travel experiences available anywhere. Each country's park system reflects its own particular landscape and history, geothermal wonders and vast wilderness in the U.S., inhabited, working countryside in the UK, and an extraordinary, globally unmatched scale of protected land in Australia, but the underlying appeal is remarkably consistent: big skies, quiet trails, and landscapes worth protecting for whoever visits next.
Plan around shoulder seasons where possible, respect entry requirements and wildlife guidelines, and choose the park that matches what you're actually looking for, geothermal drama, alpine solitude, coastal cliffs, or cultural depth, and you'll come away with a trip that does justice to some of the most remarkable protected landscapes on the planet.
