Boulder – Colorado

Your adventure begins as you arrive in the United States, where transport will be arranged to collect you from Denver. It’s well connected to Europe and the US, making your journey smooth and hassle-free. The meeting point, where we will start our journey to the mountains is in the city centre. The transfer will leave at 3pm and takes around 45 minutes. If you arrive before this time there are several luggage storage places so you can use the time to explore Denver. If you’re arriving a day early, we can suggest excellent accommodation options to ensure a relaxed start to your journey.

For the duration of the trip, you’ll be based in Boulder, surrounded by mountains and national parks. This means you won’t have to carry all your belongings from place to place, and after each day of hiking, you’ll return to the comfort of a warm shower and a cosy bed. Get ready for an unforgettable week exploring one of the US’ most spectacular mountain landscapes.

This classic Rocky Mountain National Park hike links two of the park’s most beautiful alpine lakes, offering a perfect balance of forest, waterfalls, and high-mountain views.

Starting at the Bear Lake trailhead, the path climbs gradually past Nymph and Dream Lakes, each framed by pine forest and reflections of Hallett Peak. From Dream Lake, the trail continues higher to Emerald Lake, a turquoise pool nestled beneath sheer cliffs and snowfields. The scenery here is spectacular year-round, with wildflowers in summer and ice patterns forming on the lake in winter.

From Emerald, it’s a short, rockier trail to Lake Haiyaha, a striking jade-green lake surrounded by massive boulders and towering peaks. The return follows the same route, with changing light giving the lakes new color and texture at every turn. It’s an accessible yet unforgettable hike that captures the very best of Colorado’s alpine landscape.

This demanding but rewarding loop combines two of Boulder’s most iconic summits, offering sweeping views of the plains, the Continental Divide, and the rolling foothills that define Colorado’s Front Range.

Starting from the South Mesa trailhead, the route climbs steadily through open meadows before entering pine forest and rocky terrain. The first major ascent leads to Bear Peak, where a short scramble brings you to a rocky summit with panoramic views over Boulder and the Indian Peaks. From there, a rugged ridge trail connects to South Boulder Peak, the area’s highest summit, where the quieter atmosphere and dramatic western vistas make it a perfect lunch spot.

The descent winds back through forested switchbacks and sunny clearings, often filled with wildflowers and the scent of sage. It’s a full, rewarding day on the trail that captures the best of Boulder’s mountain scenery — steep climbs, big views, and that unmistakable Colorado sunshine.

A classic summit in the Indian Peaks Wilderness, the South Arapaho Peak hike offers a full alpine adventure with glaciers, ridgelines, and sweeping views across the Continental Divide.

The trail begins at the Fourth of July trailhead near Nederland, climbing gradually through forest before opening into alpine meadows filled with wildflowers in summer. As you gain elevation, the views expand toward Arapaho Glacier and the jagged summits of the Front Range. Beyond the old mine ruins, the route steepens, eventually reaching a rocky ridge that leads to the summit at over 4,000 meters.

From the top, the panorama is extraordinary — Lake Dorothy below, the glacier shimmering in the sun, and an unbroken sweep of peaks stretching from Longs Peak to the Gore Range. Most hikers return the same way, though strong climbers can continue along the exposed ridge toward North Arapaho Peak. It’s a demanding but deeply rewarding day that captures the wild, high-altitude beauty of Colorado’s alpine country.

A free day in Boulder and Denver offers plenty of ways to relax, explore, and enjoy Colorado’s mountain culture without hitting the trails. In Boulder, you can wander the Pearl Street Mall for local shops, cafés, and street performers, or visit the Boulder Farmers Market if it’s open. The Chautauqua Park area is great for an easy stroll and mountain views, while the Boulder Dushanbe Teahouse offers a peaceful spot to unwind. You also can’t miss the stunning Red Rocks Amphitheatre.

If you head into Denver, there’s just as much to do. The city’s art scene thrives at the Denver Art Museum and the RiNo district’s colorful murals, while history lovers can explore Union Station or the Colorado State Capitol. Craft beer fans have endless options — Denver is famous for its breweries — and the city’s food scene ranges from lively markets to upscale dining. Whether you spend the day browsing galleries, relaxing by Boulder Creek, or enjoying a meal downtown, both cities capture the best of Colorado’s creative and easygoing spirit.

One of the most spectacular hikes in Rocky Mountain National Park, the Chasm Lake Trail offers dramatic alpine scenery and a close-up view of the sheer east face of Longs Peak.

The trail begins at the Longs Peak Ranger Station and climbs steadily through spruce and fir forest before breaking into open tundra with sweeping views of the surrounding peaks. Along the way, you’ll pass timberline falls and small alpine streams before the final steep section leads to Chasm Lake, set in a cirque directly beneath the towering Diamond of Longs Peak.

The setting is breathtaking — sheer cliffs rising from turquoise water, wildflowers scattered across rocky slopes, and marmots sunning themselves on the boulders. After taking in the view, return along the same route, with wide vistas of the Front Range unfolding below. It’s a demanding but unforgettable hike that showcases the rugged beauty of Colorado’s high country.

The Ouzel Lake Trail is a peaceful and scenic hike through the Wild Basin area of Rocky Mountain National Park, filled with waterfalls, forest, and alpine views.

Starting from the Wild Basin trailhead, the path follows North St. Vrain Creek through aspen and pine forest, with the sound of rushing water never far away. Along the way, you’ll pass a series of beautiful waterfalls — Copeland Falls, Calypso Cascades, and Ouzel Falls — each framed by mossy rock and cool mist. Beyond Ouzel Falls, the crowds thin as the trail climbs gently through open meadows and spruce forest toward Ouzel Lake.

The lake itself sits in a quiet basin surrounded by rugged peaks, with reflections of Mount Copeland and Ouzel Peak mirrored in the clear water. It’s an ideal spot for a rest or picnic before returning the same way. The combination of waterfalls, wildflowers, and mountain scenery makes this one of the most enjoyable moderate hikes in the park.

After an incredible week exploring the wild beauty of Colorado, it’s time to pack your bags and begin your journey onwards. Transport will be arranged to take you to the airport, or back to Denver. It’s recommended not to book a flight too early on the final day to give us time to get you back to the airport.

If you’re extending your stay, there are plenty of incredible places to explore beyond the mountains. We’d be happy to share recommendations to help you make the most of your time.

As you leave Boulder behind, you’ll take with you memories of emerald lakes, snowy peaks and unforgettable adventures in one of America’s most breathtaking landscapes. Until next time!
