Get in touch with your spiritual side and offer up your own prayer at Imperial Chapel. Explore outside for a few moments or ask if you are allowed to join the next service.
You'll be spoiled for sightseeing choice when visiting Biarritz. Imperial Chapel is a great place to start here, but there are lots of other fine places to appreciate. Cote des Basques, Grand Beach, and Biarritz Aquarium are near the house of prayer and will fill in your day nicely.
