Rio Grande Overlook — a scenic viewpoint in Brewster County, Texas at about 604 m (1,982 ft) above sea level — is a rewarding subject for landscape photographers. It sits roughly 145 km (90 mi) SSE of Alpine.
Sunrise & sunset directions
At Rio Grande Overlook the sunrise point swings a long way through the year: about 62° (ENE) at the June solstice and 117° (ESE) in late December. Sunset moves from 298° (WNW) in June to 244° (WSW) in December, and the midday sun climbs to 84° in summer but only 37° in winter.

Azimuth is measured clockwise from true north (90° = east, 270° = west). Computed for 2026; values change by less than a degree from year to year.
Golden hour & blue hour by month
Overlooks are about the sweep of the land, so low-angle light matters most: side-light at sunrise or sunset reveals ridges and texture that midday sun flattens.

Local time (America/Chicago), including daylight saving time. Golden hour runs from about −4° to +6° solar altitude, so the morning golden hour begins during blue hour, before sunrise.
Milky Way & night sky
From Rio Grande Overlook, the Milky Way core is visible in a dark sky from February through October. June gives the longest window (about 6.7 hours on a moonless night), and the core peaks around 32° above the southern horizon. Our light-pollution model puts the sky at about Bortle 1 (excellent dark-sky site), which is excellent for astrophotography.

Window when the galactic core is at least 10° high during astronomical darkness on the 15th of each month. Pick nights within a few days of the new moon. Plan exact nights with the Milky Way planner.
Estimated sky darkness: 1 Bortle 1 — Excellent dark-sky site. The Milky Way casts faint shadows; zodiacal light and airglow are obvious. Modeled zenith brightness ≈ 21.95 mag/arcsec².
Weather & best season
Long-term NASA satellite data for this area show October as the clearest month (about 32% average cloud cover) and February as the cloudiest (45%). June is the warmest month and January the coldest, which matters for gear, snow access and how long batteries last at night.

Photography tips for this scenic viewpoint
- A panorama of 3–5 vertical frames gives more resolution and a wider view without a fisheye look.
- Blue hour after sunset is excellent for towns or roads below the viewpoint as lights come on.
- Arrive 30–45 minutes before sunrise or sunset to find a composition before the light peaks.
- Use a telephoto (70–200 mm) to isolate layered ridges and light rays instead of shooting only wide.
- Check the sun azimuth for your date: front-light, side-light and back-light give three different pictures from the same rail.
- Shoot RAW to keep the most latitude for high-contrast sunrise and sunset scenes.
Season: Clear, dry air in autumn and after winter storms gives the longest views; summer adds wildflowers but also haze.
Suggested gear: Tripod, Telephoto lens, Graduated ND filter, Headlamp. Work out exposures with the depth of field, ND filter and NPF rule calculators.
