An information board at the valley’s campground, where you sign in to stay the night — and, for a stargazer, the simplest dark-sky spot of all, because you are already standing in it. The ground here is open and flat, ringed by mountains but wide to the sky, and there is almost nothing nearby to throw light back up: one small village, a scatter of buildings, and then the dark. That is the whole advantage of this place. You do not have to climb for the sky; you have to wait for it, and let your eyes do the rest. Human eyes take a surprisingly long time to reach their full night vision — roughly twenty minutes of true dark, ruined in a second by a glance at a phone. Give them that time here, lying back with the mountains as a rough black rim around you, and the sky fills in far past what it showed at first: not dozens of stars but thousands, with the pale band of our own galaxy laid across the middle of them. Stay a night, or two; the dark is free and it comes back every clear evening.

A low rise just above the valley floor, a short scramble that lifts you clear of the buildings and puts a clean line of horizon most of the way around. Height helps a night sky less than distance from lights does, but even this modest climb trades the glow of the village below for a wider, darker bowl overhead. What you have come up to see is the Milky Way — not a single object but the combined light of the galaxy we live inside, seen edge-on as a pale band stretching across the sky. In a dark sky it is not smooth. Dark lanes cut through it where clouds of dust block the stars behind, and the band brightens and thins along its length. This is also the plainest place to feel the note’s one idea. The light gathering into that band began its journey long ago — thousands of years for the nearer stars, far longer for the faint glow between them. You are looking at the past, arriving all at once. Come up before the last light goes so you can find your footing, then stay while the band emerges overhead.

A short walk from the valley’s end brings you to this lookout over Mueller Lake, a pale sheet of water fed by melting ice and colored a milky grey-green by the rock flour the glaciers grind and wash into it. By day the color is the draw. After dark, on a still night, the lake becomes something better: a mirror. Mountain basins like this one often go glassy once the day’s wind drops, and a calm lake under a clear sky holds a second sky inside it, the brighter stars and the rim of the mountains doubled on the water. It is a quieter way to watch the night than craning your neck — the sky brought down to eye level, laid on the surface. The same stillness that mirrors the stars also mirrors the mountains, so on the best nights you get the black wall of the range and its reflection meeting at the shoreline, with stars above and below the seam. Come when the air is calm; a breath of wind scatters the whole thing into ripples, and it is gone until the water settles again.

A steep climb up the valley’s eastern wall to a set of small mountain ponds — tarns, the little pools that collect in hollows scooped by old ice. The walk up is a real effort, gaining height quickly, but it lifts you well above the village and its lights and turns you to face the big peaks across the valley. That height and that turning-away are what a stargazer comes for. With the glow of the buildings now below and behind you, the southern sky opens clean. From this far south, two faint patches hang in it that most of the world never sees: soft smudges of light, easily mistaken for stray cloud, that are in fact whole separate galaxies — near neighbors to our own, drifting alongside it. They circle low in the southern sky and, from this latitude, never dip below the horizon, so any clear night will show them. Time the climb so you reach the tarns with daylight to spare, settle in as the sky darkens, and carry a good light and warm layers for the walk down, which will be fully dark and cold.

A peak on the ridge above the village, reached by a stiff climb that rewards the effort with a high, open perch and a horizon that drops away on nearly every side. By day it is a vantage over the whole valley and its glaciers. By night it becomes a platform under an unobstructed sky, high enough to sit above the last of the valley’s haze. This is the place to sort out the southern sky’s oddity: there is no bright star marking south. In the northern half of the world a single steady star sits almost exactly above the pole, and the whole sky turns around it. The south has no such marker — the sky here pivots around an empty patch of dark. To find that point you borrow a small, tilted cross of four bright stars low in the south — the Southern Cross — and follow its long axis down toward the horizon. Sailors and travelers have steered by that cross for as long as people have crossed these southern seas. Give the climb most of a day, plan to be down or well-lit before full dark, and dress for a cold, exposed summit.
