Milky Way · Southern constellations · Almost zero light pollution · Dry season skies
The sky above Costa Rica is something else entirely.
Away from the cities, the darkness is total. Kevin knows where to go — and when — to find the clearest skies and the best horizon for the southern Milky Way.
Best dark sky spots in Costa Rica
Puriscal Hills — Kevin's area
30 min from San José · Minimal light pollution · Milky Way to the south
When: Year-round on clear nights. Best: dry season, new moon.
Why it works: Sitting at 1,100m in the hills west of the capital, Puriscal is far enough from city glow that the Milky Way is visible to the naked eye. Kevin can take you to the right ridge. Combine with a farm stay.
Cerro de la Muerte — High Plateau
3,400m altitude · Arctic-clear air · Excellent dark horizon
When: Dry season only — road can be difficult in rain. Bring warm layers (it drops to 5°C).
Why it works: The highest accessible plateau on the Pan-American Highway. At 3,400m the air is thin, cold, and crystal clear. One of the darkest spots within a 3-hour drive from San José.
Osa Peninsula
Most isolated region of Costa Rica · Zero surrounding light · Southern sky
When: December–April (dry). Access can be difficult — plan ahead.
Why it works: The most remote region of Costa Rica. The Corcovado jungle absorbs all light. On a moonless night, the southern Milky Way is overwhelming.
Arenal Volcano Area
Volcano silhouette + stars · Mistico suspension bridges at night · Hot springs after
When: Best in dry season (November–April) when Arenal's summit clears.
Why it works: Some lodges near Arenal offer night astronomy walks on their grounds. The volcano's cone framing the sky is unforgettable — if it clears. Combine with hot springs.
