There’s a specific scent to the Portuguese Riviera in the morning. It’s a blend of salt spray, the faint, roasted aroma of coffee beans grinding in a pastelaria, and the damp, mineral smell of eucalyptus trees clinging to the hillsides. For the last decade, I’ve been fortunate enough to call Lisbon a second home, but my heart? It drifts west, 30 kilometers down the coast, to the golden stone and crashing Atlantic waters of Cascais.

When I first visited, I thought of Cascais merely as the "living room of the Atlantic"—a playground for the rich and a quick train ride for the weary Lisboeta. But 2026 feels like a new chapter for this historic town. The energy has shifted. The surf scene is thriving, the gastronomy is sharper than ever, and the raw, terrifying beauty of the coastline is finally being appreciated by a new generation of travelers who crave authenticity over gloss.

If you are planning a trip in 2026, you aren't just going to a beach town. You are stepping into a narrative that blends the whimsy of King Luis with the grit of big-wave surfers. You are going to meet the Atlantic, and depending on where you stand, it will either kiss your ankles or roar at you from 30 meters below.

This is your definitive guide to the beaches of Cascais and the legendary Boca do Inferno.

Part I: The Golden Miles – Navigating the Sands of Cascais

Cascais isn't just one beach; it’s a string of pearls, each with a distinct personality. In 2026, the distinction between them matters more than ever, especially if you’re traveling with family, a surfboard, or a furry friend.

1. Praia da Rainha (Queen’s Beach)

Address: Av. Rei Humberto II, 2750-000 Cascais, Portugal

Hours: Open 24/7 (Best visited at dawn)

Let’s start with the history. Legend has it that in the late 19th century, King Luis I and Queen Maria Pia fell in love with this tiny cove. They bought the land and gifted it to the town, stipulating it remain public. Today, it is arguably the most charming beach in Cascais.

The Experience: Accessed by a winding staircase or a steep path, Praia da Rainha feels like a secret. It’s small, intimate, and shielded from the strong winds by rocky outcrops. The water here is often calm compared to the rest of the coast, making it a favorite for locals.

2. Praia dos Pescadores (Fisherman’s Beach)

Address: Av. Valbom, 2750-000 Cascais, Portugal

Hours: Open 24/7

Located right in the heart of town, Praia dos Pescadores is the antithesis of the Queen’s Beach. It is wide, loud, and vibrantly alive. Historically, this is where the local fishing fleet was pulled ashore, and the tradition remains visible in the colorful boats that dot the sand at low tide.

The Experience: This is the sensory overload I crave after a few days in the city. The smell of grilled sardines wafts from the row of restaurants. The sand is soft and golden. In 2026, the promenade here has been beautifully maintained, making it an excellent spot for a stroller-friendly walk.

3. Praia do Guincho (The Surfer’s Mecca)

Address: Estrada do Guincho, 2750-000 Cascais, Portugal

Best For: Top rated beaches in Cascais for surfing 2026

Ten minutes west of the town center, the landscape changes dramatically. You leave the sheltered bay and enter the domain of the wind. Praia do Guincho is wild, untamed, and breathtakingly beautiful. It sits within the Sintra-Cascais Natural Park.

The Experience: Guincho is not for the faint of heart. The waves are powerful, the currents are strong. But for surfers, it is paradise. I remember my first time surfing here; the Atlantic humbled me within minutes.

4. Praia da Poça (The Local’s Secret)

Address: Av. Nossa Sra. do Cabo, 2750-000 Cascais, Portugal

If you drive past Guincho toward the westernmost point of the continent, you’ll find a series of smaller coves. Praia da Poça is where the locals go to escape the tourists.

The Experience: This is a rocky beach, requiring water shoes, but the reward is water clarity that rivals the Caribbean on a calm day. It’s a favorite spot for freedivers.

Part II: The Devil’s Throat – Boca do Inferno

You cannot visit Cascais without paying homage to its most dramatic landmark. Boca do Inferno translates to "Hell’s Mouth," and the name is not hyperbole.

Address: Estrada do Boca do Inferno, 2750-000 Cascais, Portugal

Hours: Mon-Sun, 09:00 – 19:00

The Legend and the Geology

Located about 2km west of the Cascais town center, this is a cliff formation where the waves of the Atlantic crash into a narrow cavern, sending geysers of water hundreds of feet into the air. The sound is deafening—a roar that seems to vibrate in your chest.

The 2026 Experience

Today, safety barriers and a paved promenade make it accessible to almost everyone. However, the wildness remains.
