Planning a trip to Gaztelugatxe from Bilbao is easy once you know two things: you may need a free ticket, and getting there is far simpler by car or tour than by bus. San Juan de Gaztelugatxe is a small rocky islet on the Biscay coast, joined to the mainland by a stone bridge and topped by a white hermitage. This guide covers the history, the 241-step climb, tickets, parking, transport and where to stay, and sits alongside our Bilbao travel guide.

Gaztelugatxe at a glance
History: what you are climbing to
San Juan de Gaztelugatxe is a hermitage dedicated to John the Baptist. The first chapel is believed to date from around the 9th century, and the site later became a religious community. The name is usually explained as Basque for “castle rock”, which is a fair description of the setting.
The coast has a turbulent history. Local tradition records that English corsairs under Francis Drake attacked the hermitage in the late 16th century, and the building has been damaged and rebuilt more than once since. What visitors see today is a restored church on a fortress-like rock, reached by a zigzag stair along the ridge.
The islet reached a far wider audience when it stood in for Dragonstone in season 7 of Game of Thrones, and it remains one of the most photographed places in the Basque Country.
The climb and the bell
From the mainland, a footpath leads down to the stone bridge and then up the islet. The stair has 241 steps, and the incline is steady rather than technical, but it is uneven and exposed. You do not need special equipment, though sturdy shoes make a real difference.
At the top, tradition says you ring the bell on the church wall three times and make a wish. Expect a short queue in busy periods. Beyond the church there is a sheltered area with benches where you can rest before heading down.
Practical tips for the walk
- Bring water and wear shoes with grip.
- Allow extra time for the descent, which can be slow when the path is crowded.
- Take extra care on the steps in wind or rain; Bay of Biscay weather turns quickly.
- Go early for the quietest light and the fewest people.
Tickets and visiting rules
Access to Gaztelugatxe is free. However, to control numbers the authorities require a free timed ticket during busy periods, booked in advance through the official booking site, tiketa.eus. Bookings generally open well ahead of the date.
The controlled periods usually include summer, weekends in spring and autumn, Easter and public holidays, and they can change from year to year. Outside those periods you can normally walk in without a ticket.
Parking
There is a free car park by the road and a small paid lot at the Eneperi restaurant, which is closer to the start of the path and costs a few euros. Both fill up in high season, and parking on the road shoulders is prohibited and fined. If the lots are full, Bakio and Bermeo are the usual fallbacks.
Getting to Gaztelugatxe from Bilbao
| Option | Time | Notes |
|---|---|---|
| Car | About 45 minutes | The easiest way. Follow signs for Bakio, then Bermeo. Arrive early for parking. |
| Guided tour | Half day | Transport from Bilbao, often with a stop at a coastal village. Good if you do not want to drive or deal with parking. |
| Bus | Slow | Bizkaibus runs Bilbao to Bakio and to Bermeo, but neither drops at the islet. Local onward buses run on weekdays only, so this is a last resort. |
| Taxi | About 45 minutes | Possible, but agree the return trip in advance since there are few taxis near the site. |
Guided tours from Bilbao
If you would rather not drive, a guided trip is the simplest option. Most combine Gaztelugatxe with other coastal stops, and some include the climb with a guide who explains the history. The booking box near the top of this page shows live availability. Check whether tickets are handled for you, since the timed ticket rules above still apply in busy periods.
What to combine it with
- Bakio: a beach town with a long surf beach and seafront restaurants close to the access road, and a natural lunch stop.
- Bermeo: a working fishing port with a harbour to wander and seafood restaurants, on the other side of the islet.
- Mundaka: a small harbour village known among surfers, with a pretty waterfront.
- Back in Bilbao: finish with a crawl around the Old Town. See our Bilbao pintxo guide.

Check AvailabilityFAQ
Do you need a ticket for Gaztelugatxe?
Entry is free, but at busy times you must book a free timed ticket in advance on the official site, tiketa.eus. Controlled periods generally cover summer, weekends in spring and autumn, and public holidays, and the dates change each year, so check before you travel.
How many steps are there at Gaztelugatxe?
The climb to the hermitage is 241 steps from the bridge that links the islet to the mainland. Allow 2 to 3 hours for the whole visit, including the walk down to the bridge and time at the top.
How far is Gaztelugatxe from Bilbao?
It is about 35 km away, roughly 45 minutes by car. Public transport is slow and indirect, so most visitors drive or join a guided tour from Bilbao.
Can you get to Gaztelugatxe from Bilbao by bus?
Partly. Bizkaibus runs from Bilbao to Bakio and to Bermeo, but neither stop is at the islet, and the local connection onward runs on weekdays only and infrequently. A tour or a rental car is far easier.
What is the best time to visit Gaztelugatxe?
Early morning on a weekday, or the spring and autumn shoulder seasons, are the quietest. Summer is the busiest, and the steps can be slippery in wet weather.
Was Game of Thrones filmed at Gaztelugatxe?
Yes. The islet stood in for Dragonstone, the island fortress, in season 7 of Game of Thrones.
