The project
A living atlas of the Alto Tajo
altotajo.es is an independent atlas of the Alto Tajo connecting 272 places, 44 routes, and 115 villages with the layers of time that explain the land: its geology, its inhabitants, its traditional trades, and the evolution of its villages. It is created by El Observario, a small-group ecotourism initiative based and working year-round in the Natural Park.
What is the Alto Tajo Natural Park
Since 2000, the Alto Tajo Natural Park has protected the upper reaches of the Tagus River and its tributaries across the provinces of Guadalajara and Cuenca, spanning more than one hundred thousand hectares of canyons, high limestone parameras, pine forests, and Spanish juniper woodlands. Much of this territory also belongs to the Molina-Alto Tajo UNESCO Global Geopark, recognized for the richness of its geological record.
What territory it covers
The atlas brings together locations from the Alto Tajo Natural Park, the historical Señorío de Molina, and adjacent areas of the Serranía de Cuenca. The Natural Park, the historical region, and the Geopark each have distinct boundaries: being listed here does not mean a place lies strictly within the Natural Park. Each entry indicates its linked municipalities.
How to read this atlas
Start with memory: pick an era, read its stories, and discover the places that still preserve its traces. The getting started guide suggests four entry points into this journey. Suggested durations are approximate, and distances between points are straight-line measurements. Weather forecasts do not certify the condition of a dirt track, footbridge, or access road.
Why an atlas
Information about the Alto Tajo is widely dispersed and frequently out of date. Here, every place is an interconnected entry: what lies nearby and how far it is, which village it belongs to, which routes depart from there, what the climate is like month by month, and what current conditions are right now.
Where the data comes from
- Places and routes: direct field documentation, cross-referenced with public sources cited on each page; hiking trails correspond to official paths from the Natural Park, the Castilla-La Mancha Mountaineering Federation, and the Diputación de Guadalajara.
- Month-by-month climate: 2015–2024 averages calculated from the European Copernicus programme's ERA5 reanalysis via Open-Meteo.
- Forecast and sky quality: real-time data from Open-Meteo; moon phases and sky clarity index are calculated directly in your browser.
- Rivers and base maps: © OpenStreetMap contributors.
Entries display editorial review dates whenever available. Opening hours, permits, and seasonal restrictions should always be verified with the linked official sources; an editorial review is not equivalent to an on-the-ground inspection. Entries still pending complete editorial text are shown so they can be located on the map, but are kept out of search engine indexes until finished.
How it is maintained
We prioritize entries most essential for planning a visit. When sources disagree, we explain the difference rather than presenting a single figure as definitive. Climate averages reflect the 2015–2024 baseline; the seasonal natural calendar describes typical patterns rather than live current observations.
Who is behind this
El Observario organizes nature activities in small groups across the Alto Tajo and Serranía de Cuenca: wildlife and bird watching, mycology, dark sky stargazing with certified Starlight guides, geology, and ethnography. Whenever an entry is linked to one of its guided outings, this is indicated clearly.
