Eugi Reservoir, forest trails and the history of the Real Fábrica de Municiones give Eugi several clear highlights for a trip. The reservoir was inaugurated in 1973 and built in the 1970s on the upper reaches of the River Arga to supply water to Pamplona and the surrounding comarca. In the town centre, a footpath runs along the shore, where information panels from the Confederación Hidrográfica del Ebro are on display. This lets you take in the reservoir while walking through the town.
The woodland also shapes Eugi’s landscape, with streams and trails running through it. The beech forests provide a habitat for red deer and roe deer. The Way of St James passes five kilometres from Eugi and crosses the Esteribar Valley from north to south.
Circular Walks and Hiking Destinations
A short, easy circular walk starts in Eugi and goes around the reservoir. The paths run through oak and beech woods and a chestnut grove, before returning to the town along a road. If you are looking for a short, easy walk, this route offers a clear point of comparison for your planning.
The Eugi–Zubiri route, which can be walked in either direction, follows several paths alongside the River Arga and passes through woodland and beech groves. After the two variants join, the next section is suitable for hiking and cycling. The route from Eugi to Azegi first passes through oak woods and meadows, then reaches the beech forest.
The route to Amuzko Peña begins north of the town centre. It leads to a natural viewpoint overlooking the reservoir, the town and the surrounding mountains, and is graded as moderate. The options described therefore differ both in difficulty and in route: from a short circuit by the reservoir to a trail leading to a viewpoint.
The EREMUA trail network passes through Eugi; an information board about routes and hiking trails is located in the town. Check trail conditions before setting out.
Industrial History and Exhibition
The Real Fábrica de Municiones de Eugi was founded in 1766 on the site of an older ironworks. It was a pioneering factory settlement in a rural setting, inspired by the French Encyclopedists. The complex covered 10,000 square metres and included coal stores, furnaces, foundries, workshops, facilities for cleaning munitions, canals and bridges. These features show the scale of the former factory and its infrastructure.
Around 500 people once lived in the factory settlement. It had its own school, doctor and church. In 2016, the Government of Navarre classified the Real Fábrica de Municiones de Eugi as an Asset of Cultural Interest (BIC) in the categories of monument and archaeological site.
The Centro de Referencia Histórica OLONDO has a permanent exhibition dedicated to Eugi, the former arms factory, the natural surroundings, and the customs and traditions of the town. Various activities related to the exhibition themes are also organised there. Individual visits are possible during opening hours on weekends and public holidays; groups can arrange visits outside these times. Confirm the visiting arrangements before your trip.
Local Festivals and Crafts
A local craft fair is held in Eugi from time to time. It includes demonstrations of Basque rural sports, traditional crafts and food tastings. Dates vary from year to year, so check the latest event details before planning a visit.
