Ondarreta Beach (Playa de Ondarreta)

If good weather's a make or break for you, you're going to want to visit San Sebastián between June and September. June and July are great months to visit, especially for those who like to stay active on holiday in comfort.

The ideal number of days depends on your travel style, but for most visitors, three to four days is the perfect amount of time. San Sebastián is not a large city, but it is rich in experiences. The city is best enjoyed at a slow pace, with time to walk along the bay, enjoy long meals, and explore neighborhoods on foot.
