Night temperatures drop fast
Bring an insulating mid-layer and a windproof shell for evening observatory sessions; temperatures can fall 10–15°C after sunset.
Protect against sun and glare
Sunscreen and a hat are useful during daytime valley visits — UV is strong at altitude even when dry.
Hydrate at altitude
Carry a 1–1.5L refillable water bottle for daytime walks; bottled water is available but scarce in some rural stops.
Bring a small daypack
A 15–20L pack holds layers, camera, documents and snacks for transfers and short hikes.
Warm mid-layer (fleece or down)
Nighttime stargazing is cold; an insulating layer keeps you comfortable during telescope sessions.

Sunscreen and sun hat

summer
Sturdy walking shoes
Paved roads and short uneven trails around viewpoints and small towns benefit from supportive footwear.
Headlamp or small flashlight
Useful for moving around the observatory grounds and hotel areas after dark without disturbing night vision.
