Other than the upscale hotel boutiques that sell scarves and poolside accessories, Estoril does not abound with shopping options. Most dedicated consumers head for the markets of Lisbon or for the large-scale shopping center in Cascais, a 10-minute drive from Estoril.
In July and August, the resort sponsors an open-air handicrafts fair, the Feira do Artesanato, near the casino. It's worth a visit even if you're staying in Cascais. The fair runs nightly from around 5pm until midnight. In addition to good regional specialties, the stalls sell handicrafts and art, including ceramics, from all parts of Portugal. You can also drive 6.5km (4 miles) southeast of Estoril to the town of Carcavelos, which has a busy market on Thursday from 7am to 5pm. You'll see local arts and crafts along with more mundane items such as food and clothing. You can also reach Carcavelos by train from Estoril; it's best to go in the morning.
