Tables and barbecue area in the picnic area. Wide area of shade. At some times of the year you can ford the Jalón River, but at other times it is necessary to climb the channel to go from one side to the other.
The construction of a canal that would carry water from the Navarrese stretch of the Ebro to Zaragoza was a project that started in the 16th century. Around 1790 the work, restarted by Ramón Pignatelli, reached Zaragoza. To do this, the problem of crossing the Jalón was solved by means of an aqueduct of around 1 km, next to which a "House of Stops" was built for travelers who made the journey from Tudela to Zaragoza by boat. To go down from the pier to the Casa de Paradas (which is still preserved) a spiral staircase was built that gives the current name to the place.

Tables and covered little buildings for barbeques in the rest area. Lots of shade from big trees. During some months you can walk or ride across the Jalon river due to the low current, but on some other times you'll need to get up to the Canal to go from the left to right bank of the river.
The project for a canal to take the Ebro river waters from the Navarre region to Zaragoza was an idea that started back in the XVIth century. About 1790 the works, restarted by Ramon Pignatelli, reached Zaragoza giving the city a second water supply. To achieve that, the issue of making the Canal go across the Jalon river was solved by bulding a 1 km long aqueduct, and beside it a staging post for the travelers that traveled by ship from Tudela to Zaragoza. To get down from the dock to the staging post (that's still in place there) they built a spiral staircase that still today gives name to the location (El Caracol / The snail).
