From the Atlantic Edge to the Pacific Rim — A Geographical Traverse of Eurasia
Crossing Eurasia is not a single journey.
It is a continental framework — a long sequence of terrains, corridors, uplands and cultural zones stitched together into one uninterrupted west–east line.
The route begins at Cabo da Roca, the westernmost point of the Eurasian landmass, and ends thousands of kilometres away on the shores of the Pacific, crossing mountains, plains, deserts, valleys, fault lines and historical frontiers.
This page is the structural hub of the project.
Its purpose is to show the geographical logic of the traverse — how each segment connects to the next and how local landscapes merge into continental systems.

Crossing Eurasia Overland: Difficult Segments and Route Barriers
Where the continental line meets border closures, restricted regions, permit systems, vehicle rules, missing roads and route-continuity problems.
Afghanistan Overland Route: Borders, Risks and Route Reality
A detailed route-barrier guide to Afghanistan as a conditional corridor between Iran, Central Asia, the Hindu Kush, the Wakhan, Pakistan and South Asia.
Pakistan–India Overland Border: Wagah–Attari and Route Continuity
A detailed route-barrier guide to the political border between Pakistan and India, where the land route between West Asia and the Indian subcontinent depends mainly on Wagah–Attari, visas, border status and vehicle-continuity rules.
India–Myanmar Overland Route: The Broken Link to Southeast Asia
A detailed route-barrier guide to the corridor between Northeast India, Bangladesh and Myanmar, where the apparent land bridge from South Asia to Southeast Asia breaks because of border restrictions, Manipur instability, Myanmar’s civil war and uncertain onward transit.
Tibet Overland Access: Permits, Restrictions and Route Reality
A detailed route-barrier guide to Tibet as a controlled plateau system, where terrain, permits, borderlands, protected areas and route approval shape overland continuity.

A route-barrier guide showing how mountains, fragmented road systems, major rivers and changing transport modes shape the final overland transition from Indonesia into Papua New Guinea.

Structure of the Route (Terrain-Based Logic)
Eurasia is too large to be divided by countries alone.
This project follows landscape systems, not political borders.
The continental line is organised into the following macro-zones:
Atlantic & Iberian Front
granite uplands, coastal cliffs, river basins, quartzite ridges
→ Portugal → Spain (Extremadura, Castile, Gredos)
Mediterranean–Continental Divide
mountain arcs, high plateaus, trans-Iberian corridors
→ Central Spain → Ebro Basin → Pyrenees foothills
Western European Lowlands
open plains, river systems, glacial landscapes
→ France → Rhine corridor → Central Europe
Carpathian & Eastern European Belt
uplifted arcs, deep valleys, forest zones
→ Poland → Slovakia → Ukraine → Black Sea Basin
Caucasus & Caspian Gateway
high ranges, volcanic plateaus, narrow passes
→ Georgia → Azerbaijan
Central Asian Interior
deserts, steppe corridors, fault systems, salt basins
→ Kazakhstan → Uzbekistan → Kyrgyzstan
Tien Shan to Altai Transition
high ridges, glacial basins, interior passes
→ Kyrgyzstan → Kazakhstan → Mongolia
Siberian & Far Eastern Arc
taiga, river giants, volcanic ranges
→ Russia (Siberia → Far East)
Pacific Termination Line
coastal mountains, fault zones, ocean edge
→ Russian Far East / Japan (depending on final segment)
Each macro-zone contains multiple terrain chapters — the building blocks of the continental crossing.
Iberian Peninsula Segment (Start of the Traverse)
The first continental segment follows the landforms of western and central Iberia.
Iberian Peninsula — Terrain Pillar Guide
Full geographical breakdown of the Atlantic → Upland → Ridge systems.
Geographical progression:
Atlantic Coast → Granite Uplands → Extremaduran Plains → Quartzite Ridges → Central Cordillera
This interior transition — from Extremaduran plains through the Tagus quartzite ridges to the mountain front — is explored in detail in the Extremadura Loop.
Published Chapters
• Cabo da Roca — Atlantic start point
• Sintra Hills — granite massif
• Lisbon → Tagus Corridor
• Alcácer do Sal — Sado River lowlands & ancient hillfort city
• Almendres Cromlech → megalithic ridge of the Évora uplands
• Évora Plateau — dry interior upland
• Mérida Basin — Roman Extremadura
• Monfragüe Ridge Break — Tagus cutting the quartzite ridge
• Garganta de los Infiernos — granite terraces & water gorge
• Sierra de Gredos — granitic highlands and passes
• Ávila — medieval walls on a high plateau
• Zaragoza — corridor pivot where the Castilian Plateau contracts into the Ebro Basin, marking the transition from interior uplands to eastward Mediterranean movement.
• Barcelona — Mediterranean threshold where inland Iberian movement resolves into coastline
Upcoming Iberian chapters will complete the transition into central Spain and toward the Ebro Basin.
Purpose of the Crossing Eurasia Project
1. To Map a Continental Line Through Terrain
The project follows the physical logic of Eurasia — ridges, basins, fault lines, deserts, river corridors and climatic transitions.
2. To Connect Local Landscapes Into a Single Structure
Every ridge, valley, canyon system or historically significant city that lies along the line becomes part of the continental spine.
3. To Create a Long-Form Travel Framework
Unlike traditional travel blogs focused on isolated destinations, Crossing Eurasia is built as a multi-year, multi-region expedition model.
How to Use This Hub Page
This page acts as:
• navigation map for all continental segments
• central index for long-distance chapters
• container for future expansions
• anchor for internal linking between regions
• SEO pillar for the entire west–east route
Every time a new chapter is published, it becomes part of this hub — strengthening both the page and the project.

Long-Distance Route Logic
Crossing Eurasia operates with segmented travel — each major environment becomes a chapter:
• ridge systems
• river corridors
• glacial basins
• desert interiors
• volcanic uplands
• coastal mountains
Each chapter links back into the larger continental line.
This modular structure allows the route to expand gradually, without losing the continuity of the west–east traverse. When a long-distance route is travelled by car, motorcycle, bicycle, campervan or another private vehicle, this segmentation also creates a separate practical question: what happens to the vehicle when one section ends, but the route continues in another form. When the route reaches rivers, islands, ferries, sea gaps or oceanward extensions beyond the mainland, this becomes an even wider question of land-water route continuity.
For readers planning their own long-distance surface route, I also created the Overland Route Cost Planner Lite — a downloadable spreadsheet for estimating the full route budget, including fuel, ferries, vehicle shipping, other transport, accommodation, food, border fees, repairs and emergency buffer. You can find this planner, the free Overland Route Fuel Calculator and future practical planning resources on the JBH Resources & Tools page.
For the practical side of this segmentation — borders, permits, restricted regions and route breaks — see Crossing Eurasia Overland: Difficult Segments and Route Barriers.
Begin the Atlantic-to-Pacific Traverse
Start the journey from the Atlantic edge:
Cabo da Roca → Sintra → Lisbon → Évora → Mérida → Monfragüe → Garganta de los Infiernos → Sierra de Gredos
Cáceres → Mérida — regional transport corridor linking the Extremadura interior into the continental line.
Madrid → Ávila — regional transport corridor linking Madrid with the Castilian Plateau.
This is the first geographical line of the Crossing Eurasia project.
