Pic du Midi, 14 – 16 August, 2026

source

Overview

We are pleased to invite AHO members to pre-register for the 2026 General Assembly, taking place 14 – 16 August at Pic du Midi Observatory in the French Pyrenees. The meeting coincides with the 12 August total solar eclipse, visible from Zaragoza (Saragossa), Spain, within driving distance of the observatory. Given the popularity of the event, early logistical planning is essential and we encourage interested AHO members and invited guests to pre-register at this time.

Pre-registration

The General Assembly meetings are for AHO members and invited guests. Members and guests who wish to attend the upcoming General Assembly in person are kindly invited to review the information on this page before completing the following pre-registration form.

Institutions interested in AHO membership and 2026 General Assembly attendance should contact the AHO Board using our contact form.

Lodging

Zaragoza

Due to increasing prices related to the eclipse, we encourage attendees to book their lodging in Zaragoza as soon as convenient. We are unable to accomodate all in the same hotel, however we were able to negotiate some discounted rates. Booking choices and instructions given below.

French Pyrenees

Lodging is possible on the observatory summit (dorm-style rooms, ~ €60-80/night)** or in the nearby towns of La Mongie, Tarbes, and Lourdes and others in the valley (prices vary). More information on these acommodations forthcoming.

** Due to the cable car operating schedule (09:00–17:30) and the 3,000-meter altitude of Pic du Midi, overnight lodging at the summit is limited for safety and logistical reasons. Each participant will be guaranteed one night at the summit (14 or 15 August) if desired, with a possible second night only if more than 20 participants wish to stay. Accommodation for three consecutive nights is not medically advisable, as special preparation is required to prevent altitude-related issues. Please also note that there is no summit access after hours; for example, guests staying overnight will not be able to travel down and return after attending evening events elsewhere.

Travel and Transportation

Zaragoza

Arrival in Zaragoza is possible by air via Zaragoza Airport (ZAZ), by rail at the Zaragoza Delicias Intermodal Station (including high-speed AVE service), or by road through the region’s extensive motorway and highway network. The nearest major international airports are Madrid–Barajas (MAD) and Barcelona–El Prat (BCN), both offering convenient onward connections to Zaragoza.

Getting around Zaragoza has day and night maps for local public transport.

We are exploring possibilities for arranged/collective transport from Zaragoza to the French Pyrenees the day after the eclipse (13 August).

French Pyrenees

Access to the Pic du Midi Observatory is possible by air via nearby airports such as Toulouse-Blagnac (TLS) (approximately 2 hours 20 minutes by road) and Tarbes-Lourdes-Pyrénées (LDE) (approximately 1 hour by road). Rail connections are available to Tarbes or Toulouse Matabiau stations, followed by road transport to the base village of La Mongie. From La Mongie, the summit is reached by a cable-car ride of about 15 minutes.

This map shows the High Pyrenees regional bus coverage between the cities of Tarbes, Lourdes, Bagnères-de-Bigorre, and La Mongie. However some of these buses are seasonal. When the schedules for summer 2026 are released, we will post them here.

Please refer to "How to Get Here?" on the Pic du Midi website for general information.

Train Connections

The following websites and network maps may be useful when planning your train connections in France and Spain:

Bus Connections

Flixbus is a budget-friendly alternative to trains in Europe—occasionally connecting cities not connected by train.

Useful Planning Websites and Apps

Confused? Consider planning with the apps and websites listed below.

Long-Distance Travel

When planning a complicated trip, Rome2Rio is a handy door-to-door travel planning app. By entering origin and destination addresses (or cities, hotels, landmarks), it outlines all available modes of transportation (plane, train, bus, tram, boat...) from beginning to end and the total travel time. However, it is always best to confirm details with the official transport providers.

Trainline offers useful comparisons between long-distance train and bus connections. Again, it is best used for planning purposes, with ticket purchases made directly through the official transport providers.

Local Transport and Navigation

Citymapper is especially helpful in major cities where Google Maps doesn’t yet have up-to-date local public transportation options. Paris, Toulouse, Madrid, Barcelona, and Zaragoza are all covered by this app.

Rural areas and smaller towns are better served by Moovit, though its interface is more cumbersome than Citymapper's and real-time accuracy varies by location.

Organic Maps is an excellent offline mapping app for travel. Download the region(s) needed while connected to wifi, and save key locations such as hotel and sightseeing spots. Once set up, the app works without using any data, making it especially convenient for getting around on foot.

Cost Effective Cell Data

In general, international data plans offered through third-party eSIM providers are much more affordable than roaming plans from traditional cellphone carriers. It’s well worth taking a few minutes to explore eSIM options. For most travelers, a couple of gigabytes per week—more than enough for maps, messaging, and light browsing—can cost just a few euros or dollars. There are also plenty of helpful YouTube videos that walk you through how eSIMs work and how to set them up. Below is a table highlighting some useful plans from popular eSIM providers.
