The Triple Lake Experience in Tyndall Gorge
It is September 21, 2026. An autumn morning in Rocky Mountain National Park that welcomes us with a clarity only found in the mountains during September. Together with my wife Hania and my sister-in-law Basia, I lace up my hiking boots right at the Bear Lake Trailhead. We find ourselves at an impressive elevation of 9,475 feet (2,888 meters) above sea level right at the start of our tour. The thin, cool air tastes crisply of pine needles, while the sky stretches above us like a flawless blue canopy. Ahead of us lies one of the park’s most legendary short routes: the chain of Nymph, Dream, and Emerald Lake, which will lead us through the picturesque glacial valley on a total round-trip distance of about 3.4 miles (5.5 kilometers).
Right from the first few yards, we feel the steady incline. In total, we need to overcome around 715 feet (220 meters) of elevation gain to reach our destination. After a short time, the dense forest opens up, and a gigantic, rocky mountain ridge shifts into our field of view. It is the mighty massif of Flattop Mountain and Hallett Peak, which will accompany us from now on like a loyal guardian at every step. Its gray, rugged flanks form a sharp contrast to the deep blue of the sky. Only a little later, we reach the first jewel of our hike: Nymph Lake. The lake lies there quiet and idyllic, almost completely covered by a dense carpet of green lily pads. The clear water catches the reflections of a few white clouds and the deep blue of the firmament.

We hike onward, and the path gains elevation. The nature around us begins to shift in color. Between the deep green pines, the quaking aspens flash up again and again—their leaves glowing in an intense, almost ethereal golden yellow, as if they had stored the sunlight of the entire summer. Suddenly, there is a rustling in the branches: a vibrant blue Steller’s Jay lands boldly right in front of us. With its proud, black crest, it looks at us cheekily, fully hoping to score a small treat. But we remain steadfast—feeding is not allowed here, even if the charming beggar accompanies us a little further.
Hania and Basia enjoy every single second. Taking a short break, they turn around; the laughter on their faces reflects pure joy in this natural paradise. Behind them, the view opens back down into an endless green valley, towered over by the gray giants Hallett Peak and Flattop Mountain. The trail itself completely captivates us now. It is fantastically constructed, winding higher in artful switchbacks made of massive natural stone steps. Sometimes the path hugs closely to shady, steep rock walls, while on the other side, the sunlight breaks through the treetops. Looking back through the branches, Nymph Lake already lies deep below us, small and precious like an emerald in the forest.

And then, almost abruptly, it lies before us: Dream Lake. The name does not exaggerate. The water is so clear that you can count every single stone on the ground in the shallow, narrow end of the lake. The deep blue of the water forms a perfect symbiosis with the steep mountain flanks. When you look upward, the dimensions take your breath away. On the left, the monumental, vertically dropping north wall of Hallett Peak shoots into the sky—a gigantic wall of gray primordial rock. To the right of it rise the rugged, wildly jagged rock formations of Flattop Mountain. We find a spot on the mighty, exposed tree roots and rocks along the shore. Hania and Basia rest, listening to the soft lapping of the water where ancient, silver-gray tree trunks drift, soaking in this endless peace.

The final section of the path eventually leads us up into the rugged, high-alpine zone above 10,000 feet. When we reach Emerald Lake, we find ourselves in a massive, horseshoe-shaped rock arena at the very end of the valley. Up here, nature becomes wild and untamed. The water of the mountain lake is dark and deep, lightly rippled by the cold wind blowing down from the glaciers. Directly above us tower the Tyndall Towers—needle-sharp, formidable-looking rock crags of Flattop Mountain that reach like stone fingers into the sky. Beneath them, a gigantic, gray sea of boulders and scree slopes down to the water, where isolated, resilient conifers defy the barren environment. A hiker on the distant shore appears tiny, almost vanishingly small against these monumental walls of Hallett Peak and Flattop Mountain.
As we finally begin our return journey and leave the Tyndall Valley, the day grants us one last, unforgettable farewell greeting. From a viewpoint, we look deep into the neighboring Glacier Gorge. It is a panorama of superlatives: before us extends an endless, dark green carpet of conifers, broken up in the foreground by golden-yellow aspens. On the horizon, however, throne the mighty high peaks. On the left side of the valley rises the prominent Chiefs Head Peak, followed by the rugged rock teeth of the Keyboard of the Winds. Exactly in the center stands the unmistakable, massive, flat summit of Longs Peak alongside Pagoda Mountain, and on the right, the massive ridge of Thatchtop Mountain borders the deeply carved glacial valley. A perfect finale for a perfect autumn hike in the Rocky Mountains.
