The return of warmer weather and sunnier days means it's a great time to get out and explore more of the great outdoors. And as a new season dawns, America's mountains come alive with greenery – here we've narrowed down some of the best and most beautiful mountains to make the most of the season. As always, if planning a trip, check state travel advisories first and national or state park opening times, restrictions and closures. 

The grande dame of Yosemite National Park (along with Half Dome to the east), El Capitan rises proudly from the western side of the Yosemite Valley. Its granite face appears near vertical – a result of glacial action that shaped many of the mountains within the national park. There are several trails suitable for all abilities that make for excellent hikes, especially when the grey granite mountains are contrasted by the lush foliage.

A mountain range within the Rocky Mountains, the Teton Range is an icon of the Cowboy State. Stretching along the Idaho state line from north to south, the range is mostly within Grand Teton National Park in Wyoming, named for the highest mountain in the range. There are almost endless possibilities for trekking and hiking here and trails range from easy walks that take a couple of hours to strenuous full-day climbs.

Not everyone is lucky enough to be able to explore the remote Denali National Park and Denali mountain. Surrounded by unspoiled landscapes mostly enjoyed by bears, wolves, caribou and moose, it makes for unbelievable hikes. If visiting Denali, be mindful that it's a true wilderness so you must be prepared. If you want to see the mountain itself, Reflection Pond is one of the most gorgeous viewpoints as Denali is mirrored perfectly in the still water. 

At 6,288 feet (1,917m), Mount Washington is New Hampshire's highest peak, dominating a verdant valley that bursts with colour in every season. However, if you're not keen on a hike, you're in luck. The mountain is home to the world’s first mountain-climbing cog railway, in operation since 1869. Brightly coloured trains chug along the 3.5-mile (5.6km) track, at a 37% gradient at certain points. At the summit, you'll have an hour to take in the views that on a clear day include five states, Canada and the Atlantic.

Another one for those not in favour of a hike, the breathtaking Skyline Drive is a dream road trip perfect for taking in the beauty of the Blue Ridge Mountains. The serpentine route starts 75 miles (121km) west of Washington DC and follows the crest of the mountains. The narrow 1930s road winds through forests, meadows and steep slopes, and you might even spot white-tailed deer, bobcats or black bears.

A few hours north of New York City, skyscrapers are swapped for mountain peaks, whose snowy winter caps melt into rivers and lakes come spring. Sidewalks are replaced with tree-lined paths and trails, suited for all abilities, that skip past meadows and waterfalls. If you'd rather turn it into a road trip, there are more than 15 scenic drives in the Adirondacks.

The highest point in the Natural State, Mount Magazine sits at 2,753 feet (839m), offering panoramic views across its namesake state park. One of the best ways to enjoy this forest-clad landscape is taking the Signal Hill Trail. The trail takes hikers straight to the top of Signal Hill, one of the two summits atop Mount Magazine. It's an enjoyable 1.5-mile (2.4km) loop around the north and east parts of Signal Hill. 

Table Rock, rising to 3,950 feet (1,204m), is the backdrop of this breathtaking state park of the same name. But Pinnacle Mountain is the tallest peak entirely within state borders. There are over 15 miles (24km) of trails, including 7 miles (11km) of mountain bike trails and plenty of opportunities to not only reach the summit, but also explore the rivers and valleys. Those looking for a challenge should pick the Pinnacle Mountain Trail. It lasts for some three miles (4.8km) with plenty of steep uphill stretches thrown in along the way.

The Elk Mountains in Colorado are crammed full of inspiring viewpoints and winding trails that snake through the enchanting landscapes. Yet nowhere is quite like the Maroon Bells. The two peaks are the most well-known in the region – and for good reason. These soaring mountains are incredible to both climb and look at. The scene is especially serene on sunny days, when the two peaks are reflected in the still water of Crater Lake.

The scenery of Grayson Highlands State Park is often compared to that of the Alps. Situated close to Mount Rogers and Whitetop Mountain, it's a paradise filled with mountain-fringed meadows, woodland and waterways and, best of all, it's home to wild ponies who graze on the park's grasses. There are 13 different hiking trails as well opportunities for biking and canoeing for those who prefer to take in mountain views from level ground.

Mount Shasta soars from the Cascades to 14,179 feet (4,322m). While these head-spinning heights remain the reserve of the most daring climbers, there's no reason why you couldn't get a fine view of the peak from ground level. The road from Mount Shasta City offers a gorgeous view of the mountain and a 14-mile (22.5km) scenic drive showcases the most picturesque scenery around.

The national park in which the Great Smoky Mountains, also known as the Smokies, are located, is the most-visited in the country.

A section of Alaska Route 1, also known as the Seward Highway, runs through several scenic spots like Kenai Peninsula, Kenai Mountains and Chugah National Forest on its route between Anchorage and Seward. The drive takes just four hours to complete, but you could turn it into a two-day itinerary to properly take in the jagged peaks and alpine meadows.

The Rockies might be Colorado's most famous, but the San Juan Mountains have one of the best scenic drives in the world – the San Juan Skyway. Winding for 233 miles (375km) through the mountains, there are fascinating places to stop, from historic railroad town Durango to ski resort Telluride. But it’s the twists and turns, at some points revealing mountain-ringed lakes and at others bringing you to the edge of dramatic canyons, that’ll linger longest in your memory.

A destination that attracts plenty of leaf-peepers in autumn, the White Mountains and the dense White Mountain National Forest that covers the slopes are simply magnificent in any other season too. One of the best ways to enjoy the scenery is driving the Kancamagus Scenic Byway. The road follows the path of the Swift River and hiking trails peel off the road and into the forest, offering a chance to combine a road trip with a hike or a casual stroll.

Too often Utah's Wasatch Mountains and the state park of the same name get overlooked in favour of some of the state's more famous names, but this quieter corner of Utah is worth a visit.

There are also six canyons, mountain ski towns and backcountry hideaways to explore here too.

The Sangre de Cristo Mountains are the southernmost subrange of the Rocky Mountains and the mountain slopes look more like a painting in any season.

This is the most scenic byway in every state

A mountain range located in Big Bend National Park, Chisos, as they're also known, form the heart of the park. Characterised by dramatic and seemingly endless landscapes, the park gives a feeling of complete isolation. Here, rivers have carved vast caverns out of limestone and the mountains sit surrounded by the Chihuahuan Desert. There's a 7-mile (11.2km) paved road that climbs into the mountain basin where an extensive network of hiking trails, ranging from half-mile (800m) strolls to challenging trails up to 14 miles (22.5km) long, start.

The Tallulah Gorge, carving its way through the mountains, is nothing short of spectacular. Dramatically plunging to 1,000 feet (305m), the water carves its way through two miles (3.2km) of forest-covered rock.

Highlights of the park include the gushing Hurricane Falls, which is accessible via the Hurricane Falls Trail, a two-mile (3.2km) loop studded with scenic outlooks.

The highest peak of the Appalachian Mountains, Mount Mitchell rises 6,684 feet (2,037m) above sea level, overlooking its namesake state park and the Pisgah National Forest. A visit to the peak can easily be combined with a drive along the incredibly scenic Blue Ridge Parkway and on a clear day it's possible to see as far as 85 miles (137km) from the top. It's also possible to park your car at the State Park office and hike your way to the top. A strenuous climb – 2.2 miles (3.5km) long each way – it's also incredibly rewarding.

There's no arguing that Mount Rainier is of an epic size. With more than 130 trails snaking their way through the forested area around the mountain, there are plenty of opportunities to take in the stunning scenery.
