Eclipse August 12, 2026 · Soria, Spain · Ranked
The 4 best terrain-verified spots to watch the 2026 eclipse in Picos de Urbión & Laguna Negra
2 of 4 checked viewpoints have a verified-clear terrain view of the low eclipsed sun. Ranked by ray-cast clearance, totality duration and 20-year clear-sky odds.
Every viewpoint below was checked with Heliora’s terrain engine: a 360° ray-cast of real elevation data from its exact coordinate, compared against the sun’s position through the eclipse. The ranking puts verified-clear spots first (by clearance margin), then totality duration and historical clear-sky odds.
Each verdict comes from ray-casting 360° from the exact coordinate over Mapbox Terrain-RGB elevation data (30 km range) — the same engine as Heliora’s live 3D sky view. Clearance margins under ~1° are flagged marginal: elevation pixels are ~75 m wide and can miss sharp ridge lines, and trees and buildings are not included. Clear-sky odds are 20-year ERA5 climatology (2005–2024, ±3 days around Aug 12, cloud cover ≤20% at the local peak hour) — historical odds, not a forecast.
