A birthday among the trees and zip lines! At Castro Park, children share the adventure with their friends and then have an allocated area with tables for birthday snacks. We are in the Campijo neighbourhood of Castro Urdiales, with car parking and a terrace bar.
Check your date before organising the group
Send us your preferred date or dates, the approximate number of children, their ages and whether you would like food, birthday snacks or a barbecue. Mention any children under 9 or special requirements. We will confirm availability and conditions before you book.
Ask Castro Park about availability
What the activity includes
Treetop courses, bridges, balance challenges and zip lines, including the park’s large zip lines. Before starting, participants receive a harness and helmet and are given a safety briefing. The activity lasts around two hours; this can vary with visitor numbers, the group’s pace and the organisation of the day.
Requirements and adult supervision
The minimum height is 1.05 m and the maximum weight is 110 kg. Participation depends on these requirements and safety conditions, rather than age alone: a child aged 4 or 5 can participate if they meet them. Ask us beforehand about any doubts, fear of heights, injuries or reduced mobility.
Children under 9 must be accompanied by an adult. For birthday parties or groups of more than 6–8 children that include children under 9, they must be accompanied by 2 or 3 adults. Those accompanying adults do not pay.
Birthday prices and start times
For birthdays with more than 10 children, the activity costs €16 per child. Extra food ordered in advance costs an additional €5 per person. Morning sessions start from 11:00 and afternoon sessions from 16:00, subject to park availability.
Birthday snacks, food and barbecues
You can bring or order food, or prepare it in the barbecue area, which requires advance booking and has its own conditions. Drinks must be purchased at the bar: bringing drinks from outside the park is not permitted.
Before your visit
Tell families to bring comfortable clothing and closed sports shoes, tie back long hair and keep loose objects out of pockets during the activity. Arrive with time to check the group, complete participation forms, collect equipment and attend the safety briefing.
The activity is suspended during thunderstorms and, in summer, may be paused or cancelled if the temperature exceeds 30°C. If Castro Park cancels because weather conditions prevent the activity from taking place safely, a refund or a change of date is offered.
