I had a great two-day walk on the Ruta del Ebro from Tortosa to Gandesa. The 42+ kms covered were quite challenging due to the 36°C (97°F) days and the large distances between fountains. Luckily, my umbrella provided some constant shade.
Tortosa to Benifallet
Via Verde all the way. From Tortosa, it is best to start by visiting the Portal del Romeu and then crossing the bridge that the locals say uses the same color paint as the Golden Gate Bridge. Along the Via Verde, I was able to find ripe figs, green almonds, carob, and black berries to nibble on. Rosemary and wild fennel flavored my water.
I had a late start and walked in the midday heat arriving at the Estació de Benifallet around 5:15 pm. I was the only person at the albergue section and enjoyed a cold shower (hot water was available) and the air conditioned room.
The restaurant opened for dinner at 8:30 pm and offered a fortifying meal. Breakfast was from 8:30 am and included a cured meat and cheese plate, coffee, fresh orange juice, pa amb tomaquet, and a slice of cake. It was also possible to get a tortilla. Bed plus dinner and breakfast for 40.5€.
Benifallet to Gandesa
The heat did not let up and there was less shade than the previous day. Arriving to Foncalda took me off the Via Verde. Plenty of Spanish and French tourists splashing around in the thermal water there. The ascent to Gandesa was brutal in the heat. I only carried 1.5 L of water, but would have been better off with 3 L. For me, it was a more difficult walk than O Cebreiro or Pyrenees Napoleon Route. I had to take a number of breaks and even let out a few screams of anguish.
Gandesa seemed nice, but I had to take the bus back to Tortosa.
The Ebro is a lonely walk, but sometimes that is what is needed. The scenery was nice and the local food is great around the Terres de l'Ebre if you know where to go.
I will walk the Frances again, but will probably try to avoid some of the crowds by taking the Salvador and Primitivo options well described on this forum. I also think that finishing the Ebro (outside of summer) is in my future.
