Climbing the 258 twisting steps inside the 73m-high Phare de Biarritz, the town’s 1834 lighthouse, rewards you with sweeping views of the Basque coast; reserve slots in advance on the tourist website.
From the Grande Plage, it is a scenic 20-minute walk or 10-minute jog (1.59km) to the lighthouse along the Chemin du Phare, a signposted fitness trail sporting a couple of activity stations with scannable QR codes to access the different exercises.
