Carretera de la Coca San Rafael Falls Access Route
Oil road to Ecuador's highest waterfall through Amazon
Built by Texaco in the 1970s to reach oil fields deep in the Ecuadorian Amazon, this road punches straight through some of South America’s most pristine rainforest to reach San Rafael Falls — at 150 meters, Ecuador’s highest waterfall where the Coca River plunges off the Andean escarpment. The road starts in Baeza at 1800 meters and descends through six distinct ecological zones, past Cecropia trees thick as telephone poles and river crossings where you’ll see toucans and maybe jaguar tracks in the mud.
This is wet, technical driving through active logging and oil territory. You need high clearance 4WD, mud tires, and a winch — the road turns to chocolate soup in minutes when it rains, which is most days. Go June-September for the driest conditions, but expect mud regardless. No permits but check with military checkpoints about current road conditions and paramilitary activity. Fuel in Lago Agrio, camp wild where the canopy allows. What you get is access to some of the most biodiverse terrain on earth and a waterfall that’ll humble any rig.

Frequently asked questions
Can a stock Hilux or 4Runner run this trail, or does it need to be modified?
A stock high-clearance 4WD will struggle here. The mud sections and water crossings require a lifted vehicle with aggressive all-terrain or mud-terrain tires minimum — a locker helps significantly. Don't attempt this in anything less than a modified 4WD.
When is this trail actually passable, and what happens if you go outside the dry season?
June through September is the dry window. Outside of that, the Amazonian wet season turns the dirt surface into deep, relentless mud that has stopped even well-built rigs cold — recovery in that terrain is a serious situation with no cell service and sparse traffic.
Are there permits required to drive this route or access the San Rafael Falls area?
The Ministry of Environment Ecuador manages the falls access area and has required entry permits in the past; confirm current requirements before departure as regulations have shifted since the falls partially collapsed in 2020. Check with Ministerio del Ambiente offices in Lago Agrio or Quito for the latest.
What's the hardest section of this trail and what makes it dangerous?
The most serious sections are the unmarked river crossings mid-route — water levels change fast with upstream rain you won't see coming, and the clay-mud banks on either side offer almost no traction on exit. Factor extra time here and probe crossings on foot before committing.
How far is the nearest fuel from the trail, and is 58 miles enough range to worry about?
Lago Agrio is your last reliable fuel stop before heading in — top off completely there. The route runs through active oil infrastructure country so you may see fuel operations, but don't count on buying fuel out here; carry enough for 150+ miles to account for low-speed mud crawling that destroys your economy.
