Gaztelugatxe, Bermeo and Gernika Tours from Bilbao

Price, Length and the Islet Visit

The table lines up each tour's price, total length, what it does at San Juan de Gaztelugatxe and whether it holds the access booking, with every figure taken from the tour's own listing.

Where Each Day Starts and How Big the Group Is

Meeting points and group caps differ more than prices do. This table gives each tour's start point in Bilbao, its group size and its guide languages, as each listing states them.

The Short Version

On a budget, the $33 coach day gives the islet 2 hours of free time and still stops in Bermeo for 30 minutes and Gernika for 45. For the most time in the towns, the $78 walking day spends 2 hours walking at Gaztelugatxe, 30 minutes on a Bermeo visit plus 105 minutes of free time there, and 2.25 hours in Gernika. The $55 txakoli day is the longest at 10 hours and adds 2.25 hours in Mundaka and a tasting at Bodega Berroja.

The $77 day is the one with smaller-group and private options, though it visits Mundaka instead of Bermeo. The $68.11 Bizkaia Bridge day suits anyone who would not walk the 241 steps anyway.

How the Stops Are Timed

Each listing breaks the day into stops with their own minutes. The table shows the time each tour gives Gaztelugatxe, Bermeo and Gernika, so you can see where the hours actually go before you compare prices.

What Changes the Order

The islet runs on timed access on busy days, and the tours plan around the slot they hold. The txakoli day says the order may change with the time slot the Gaztelugatxe authorities assign, which can put the winery before lunch. The walking day says the order of stops can vary for operational reasons and seats are not assigned.

Drive times are short: the coach day lists 45 minutes from Bilbao to the islet and 25 minutes on to Bermeo, and the txakoli day lists 1.5 hours by coach to the islet. Lunch is not included on any of the five, so plan to eat during free time in Bermeo or Mundaka.

The Two Routes and the Steps

The path is a loop on two marked routes. The provincial council gives the length and the slope of each, and the table adds the stone bridge and the steps at the end.

Why the Tour Time Feels Tight

The official 2.5 hours is longer than any tour gives the islet. The txakoli day allows 110 minutes, and the coach day, the walking day and the Mundaka day allow 2 hours. That is enough for a steady walker, but there is little slack for long photo stops or a rest at the top.

If you are slower on climbs, start straight down the Urizarreta route, ring the bell and come back up the gentler Ermu route without detours. The way back is the harder half on the legs, since the climb out of the cove comes after the 241 steps. Picnic tables sit along the Ermu route, and there are only two sets of toilets: by the Urizarreta attention point and at the Ermu control point.

The Controlled-Access Calendar

The Bizkaia Provincial Council publishes the calendar each year, and bookings open only for the current year. These are the days that need a free ticket in the current calendar:

• 28 March to 12 April, then 18-19 and 25-26 April
• 1-3 May and every Saturday and Sunday in May
• 6-7 and 13-14 June, then every day from 15 June to 31 August
• Every day from 1 to 20 September, plus 26-27 September
• 3-4, 10-12, 17-18, 24-25 and 31 October, and 1 November
• 5-8 December and 30 December

Free-Access Days and the Rules on Booked Days

January, February, 1-27 March and most of November and December need no ticket at all. On booked days, staff at the attention points check each reservation, and you show the ticket printed or on your phone. Keep the confirmation email until you finish the route.

Entry is only allowed in the slot you booked. A booking cancels itself if you have not arrived 60 minutes after the stated time, and a no-show blocks new bookings for one year. One online request holds up to 10 tickets.

To cancel, use the link in the confirmation email.

Which Tours Hold the Booking

The coach day, the txakoli day, the Mundaka day and the walking day all list the access booking or entry ticket as included. The coach day says the tickets are included if required, which matches the calendar: on a free-access day there is nothing to book. The Bizkaia Bridge day lists the walk down to the hermitage as not included, so no islet booking comes with it.

With 1,462 places a day and summer days filling, book early for July and August either way.

What You Find at the Top

The first building is thought to date from the 9th century, and it became a convent in the 12th century. In 1334 Alfonso XI of Castile besieged the rock for more than a month. The hermitage burned in 1978, and the present building is a reconstruction finished in 1983.

At the top, a bell hangs on the front wall. Turismo Euskadi says to ring it three times for good luck and to chase away evil spirits. Bermeo tourism calls the chapel the most visited pilgrimage site on the Basque coast, and sailors and fishermen leave offerings such as ship models and photos in the chapel.

Dragonstone and the Legend

Turismo Euskadi lists the islet as Dragonstone, the castle of Daenerys Targaryen in Game of Thrones. Visit Biscay notes that the show replaced the hermitage with a large castle, so the real top looks different from the screen. Older stories run deeper.

Legend says St John the Baptist took three strides from Bermeo to the hermitage and left a footprint on the last step, and stepping in it is said to bring luck. Gaztelugatxe was declared a protected biotope in 1998, joined Natura 2000 in 2013 and became a Natural Monument in 2023. Drones are banned, and dogs must stay on a leash.

Bermeo, the Port Behind the Islet

Gaztelugatxe belongs to Bermeo, and the ties are old. From the 17th century the Bermeo council processed to the islet, and the procession still takes place on 29 August. Bermeo fishing boats make several turns around the islet for luck, including when a new boat is launched.

Hegaluze boats also leave from the port of Bermeo. The tours give the town between 30 and 40 minutes on a guided walk, except the walking day, which adds 105 minutes of free time there, enough for lunch at the port.

Gernika and the Assembly House

The Basque Government names Gernika the cradle of Basque identity. The walking day and the Bizkaia Bridge day both list the Casa de Juntas and the Tree of Gernika among their stops. Time in town varies widely: 45 minutes on the coach day and the txakoli day, 1.5 hours on the Mundaka day and 2.25 hours on the walking day.

From Gernika, the BI-2235 road leads to Bermeo, and the drive on to Gaztelugatxe takes about one hour in total. If Gernika matters more to you than the islet, the walking day gives it the most time.

Matching the Tour to Your Fitness

The official advice is clear: the walk is physically demanding. People with reduced mobility can enjoy the view from the lookout on the Ermu route instead. The Bizkaia Bridge day suits them best, since it stays at a viewpoint above the islet.

The txakoli day calls for a moderate amount of walking and hiking or sport shoes, and it is not suitable for wheelchair users. The walking day describes a hike of at least 5 km with uphill sections and is not accessible for slow walkers. The coach day reminds you of the 241 steps and runs rain or shine.

Families on a budget should note the coach day's 50% discount for children aged 2 to 12, as long as 2 adults come along.

Boats from Bermeo

None of the five tours includes a boat. If you want the sea view, add it on a separate day from Bermeo, where the Hegaluze boats leave from the port. The coast around the islet is a protected area: diving and shellfish gathering are banned, and the small islet of Akatx next to it is a seabird sanctuary.

Further west, Cape Matxitxako is the most projecting cape on this coast, with whale and dolphin watching from summer to autumn. A boat suits anyone who cannot manage the 35% climb back out of the cove.

Bus, Train or Car

From September to June there is no direct bus from Bilbao. Take Bizkaibus A3518 to Bakio or A3527 to Bermeo from Plaza Eliptica, then the A3524 van-taxi from Bakio, which takes cash only. Turismo Euskadi says the winter Taxibus runs only on workdays and holds a maximum of 8 people.

Euskotren line E4 runs from Bilbao Matiko to Bermeo, and a bus covers the last stretch. By car it takes about 45 minutes from Bilbao. Urizarreta has a 22-space public car park and Lurgorri has 57 spaces, both behind a 2-metre height barrier.

Car parks are often full from 10:00 to 16:00, and Bermeo tourism advises leaving the car in Bermeo. For timetables, call Bizkaibus on 946 125 555.

Dates to Avoid and What to Pack

The province reserves 24 June, 31 July, 29 August, 31 August and 30 December for local celebrations and asks tourists to avoid those days. 24 June is the busiest pilgrimage day. On orange-alert weather days, the province advises against climbing to the hermitage during the affected hours. The attention points and first-aid kit are staffed 10:00-19:00, and the site has a defibrillator.

Wear comfortable clothes and footwear, carry water and add sun cream in summer. If bad weather changes your plans on an independent visit, cancel online so someone else can use the place. On a tour, the operator sets the slot.
