São Miguel and Terceira are two of the most diverse islands in the Azores, offering a unique mix of volcanic landscapes, crater lakes, waterfalls and dramatic coastlines.
While São Miguel is known for its geothermal areas, tea plantations and lush green scenery, Terceira stands out with volcanic caves, scenic viewpoints and a more rugged, untouched feel.
In this guide, I’ll show you the best nature highlights and must-see spots on both islands – including a few great hiking routes to explore them more deeply.
Nature highlights on São Miguel and Terceira
The Azores offer an incredible variety of landscapes, and São Miguel and Terceira are two of the best islands to experience it.
São Miguel stands out for its crater lakes, geothermal areas and lush green scenery. Highlights like Sete Cidades, Lagoa das Furnas and the Chá Gorreana tea plantations make it one of the most diverse islands in the Azores.
Terceira feels more rugged and less visited. Here, you’ll find volcanic caves, wide viewpoints and dramatic coastal scenery. Spots like Algar do Carvão and the cliffs of Baías da Agualva offer a very different experience compared to São Miguel.
This guide focuses on the best nature highlights on both islands, with a few hiking options to explore them in more depth.
Car rental on the Azores – is it worth it?
Exploring the Azores is easiest by car. Many highlights like Sete Cidades, Lagoa do Fogo or remote coastal areas are difficult to reach without one.
I usually book my rental car in advance, as prices are often lower and availability is better.
🌍 My recommendation:
👉 Find rental cars on the Azores*
✔️ Free cancellation & transparent pricing
Driving on the Azores
Driving on the Azores is generally easy, but roads can be narrow and curvy, especially in rural areas. Drive carefully, follow speed limits and watch out for animals on the road. Fuel stations can be sparse in remote areas, so plan ahead.
Public transport on the Azores
Buses connect the main towns and tourist areas and are a budget-friendly option. However, schedules can be limited, especially in remote regions. For flexible hiking plans, a rental car is usually the better choice.
