Caspe and Mequinenza are not rival rivers. They are two important fishing bases on the wider River Ebro system in Aragón, and that distinction matters when anglers compare where to stay for a Spanish fishing holiday.
Mequinenza sits around the confluence of the Ebro, Segre and Cinca and between the Mequinenza and Riba-roja reservoirs. Caspe lies farther upstream on the Mar de Aragón side of the same broad Ebro system. Both have long associations with visiting anglers.
Quick verdict: Caspe or Mequinenza?
Choose Caspe if you want a River Ebro holiday built around the Mar de Aragón, guided Wels catfish, carp and predator options, and accommodation organised from one established base.
Consider Mequinenza if you specifically want to fish the confluence area and the waters around Mequinenza and Riba-roja, or you already have a guide or venue there that suits your preferred style.
Neither location invalidates the other. The useful question is which base gives your group the fishing, access and holiday structure it wants.
Where are Caspe and Mequinenza?
Both are in Zaragoza province, Aragón. The Mar de Aragón reservoir extends between the upper limit near Escatrón and the Mequinenza dam, so anglers talking about 'Mequinenza Reservoir' or the 'Mar de Aragón' can sometimes be discussing different areas of one very large body of water.
Mequinenza itself is positioned at the meeting of major rivers and is also associated with the Riba-roja reservoir downstream. Caspe is an established base on the Mar de Aragón section, with fishing access spread across reservoir and river-influenced areas.
Catfishing from Caspe vs Mequinenza
Both areas are closely associated with Wels catfish. Mequinenza has an established international catfishing reputation and a substantial fishing-guiding industry. Caspe also provides access to the Ebro system's Wels fishery and supports guided catfishing as part of a broader fishing-holiday offer.
For anglers specifically researching catfishing in Spain, the more important variables are usually guide quality, current fish location, method, water conditions and how the trip is organised.
Carp, zander and black bass
This comparison is not only about catfish. The wider Ebro system supports carp, zander and black bass opportunities as well, and Mequinenza tourism information also highlights carp, black bass and zander alongside Wels catfish.
For mixed groups, Caspe's appeal is that the fishing holiday can be planned around several target species without changing destination. See our River Ebro fish species guide for more detail.
Fishing water and access
Mequinenza's location near the Ebro, Segre and Cinca confluence gives it a distinctive river-junction character, while nearby reservoir sections add further options. Caspe's fishing is strongly associated with the huge Mar de Aragón reservoir and its varied banks, bays, channels and open-water areas.
The better base therefore depends partly on the type of fishing you want to do. Bank access, boat use, current water level and the guide's local knowledge can matter more than the town name on the accommodation booking.

Guides and trip organisation
Both towns have businesses serving visiting anglers. Mequinenza has long had authorised fishing-guide operators and fishing-focused tourism. Caspe likewise has tackle shops, accommodation, access points and businesses built around anglers using the Mar de Aragón.
What matters is the exact package. Compare accommodation, number of guided fishing days, tackle, transport to swims, licences, bait arrangements and what happens when conditions require a change of plan.
Accommodation and holiday style
For many UK anglers, the fishing base is also the holiday base. Caspe Fishing packages are structured around accommodation in Caspe with guided fishing options, making it straightforward for groups that want one booking to organise the core trip.
Mequinenza also has fishing accommodation and guide businesses, but inclusions vary by operator. Compare like for like rather than using headline prices from different package types.
Which base is better for first-time visitors?
First-time Ebro anglers often benefit from choosing the base where the complete trip is easiest to understand. If accommodation, tackle and guiding are already arranged around Caspe, that removes several planning decisions.
Mequinenza can be the better choice where a particular guide, stretch or method is the reason for travelling. Experienced Ebro anglers may also have strong preferences based on previous trips.
Which is better for mixed-species groups?
Caspe is especially useful when a group wants a combination of Wels catfish, carp and predator fishing from one holiday base. The Mar de Aragón is a large, varied system, so flexibility can be built into the trip.
Mequinenza also offers several major species, so the deciding factor should be the guide, intended fishing area and package rather than an assumption that one town only offers one type of fishing.
Licences and current rules
Fishing on the Ebro system is regulated. Requirements can depend on the water, species and fishing method, and anglers should confirm current licences and permits before travelling.
