Walk toward the marina once you exit the station. You will pass many charming cafes and local shops. This area is perfect for grabbing a quick snack. Buy some water before you start the coastal walk.

Look for the red paved path along the water. This path is dedicated to walkers and cyclists alike. It keeps you safe from the main road traffic. The ocean will be on your left side throughout.

The path is mostly flat and very easy to follow. You do not need professional hiking boots for this. Comfortable sneakers will work well for this specific route. The total distance is roughly two kilometers one way.

Highlights of the Coastal Path

You will soon reach the Santa Marta Lighthouse Museum. This iconic building features striking blue and white tiles. It is one of the best ocean view hikes in Lisbon. Take a moment to capture some beautiful photos here.

The museum costs five Euros to enter in 2026. You can learn about the history of Portuguese lighthouses. The views from the top are truly breathtaking and wide. Visitors love the contrast of the white tower against the sea.

Continue walking past the luxury Condes de Castro Guimaraes. This palace looks like a fairy tale castle by the sea. It sits inside the lovely Marechal Carmona Park grounds. You can explore the gardens for free every day.

The air smells of salt and fresh pine trees here. You will see local fishermen on the rocks below. They catch fresh fish for the nearby seafood restaurants. The atmosphere is very peaceful and relaxing for visitors.

Exploring the Boca do Inferno Chasm

You will hear the ocean before you see it. Boca do Inferno means the Mouth of Hell in English. It is a unique cave created by the waves. The limestone cliffs have eroded over many thousands of years.

There is a secure viewing platform for all visitors. You can watch the massive waves crash into the rocks. The spray often reaches the top of the cliffs. It is a powerful display of the Atlantic's energy.

Visit during a storm for the most dramatic views. The sound of the water is like loud thunder. On calm days, the water is a clear turquoise. Both versions offer a very different but beautiful experience.

There are several souvenir shops located near the chasm. You can buy local crafts and postcards for home. A small cafe serves coffee and traditional Portuguese pastries. It is a great spot to enjoy the view.

Tips for Hiking from Cascais to Boca Inferno

Wear a hat to protect yourself from the sun. There is very little shade along the coastal path. The sea breeze can make you feel cool quickly. However, the Portuguese sun remains very strong all year.

Pack light but bring all of your essentials along. Check our guide on what to pack for Lisbon hikes. A small backpack is better than a shoulder bag. This keeps your hands free for taking photos.

Use the public restrooms located near the Cascais marina. There are fewer facilities once you reach the cliffs. Most cafes require a small purchase to use toilets. Carry some small coins for these situations in 2026.

Stay on the marked paths at all times. The cliffs can be slippery and dangerous near the edges. Do not climb over the safety railings for photos. Your safety is more important than a good picture.

Best Time for Your Coastal Adventure

Spring is the ideal time for this coastal hike. Wildflowers bloom along the path during April and May. The temperatures are mild and perfect for walking outside. You will avoid the intense heat of the summer.

Fall also offers great weather for hikers in Portugal. September and October have warm days and cool evenings. The crowds are much smaller than in the summer. This makes the experience much more personal and quiet.

Sunset is a popular time for this specific walk. The sun sinks directly into the vast Atlantic Ocean. The cliffs glow with a warm and golden light. It is the most romantic time for a stroll.
