I don't understand the warnings about the "intensely coloring water." Maybe on swimwear, but not on the skin. I liked it.

It smells a bit strongly of sulfur here. It's smoking and bubbling everywhere.

Yes, several natural monuments are suitable for families. Furnas Lake offers easy walks around its shores and the chance to see geothermal activity.

Parque Natural da Ribeira dos Caldeirões also combines natural beauty with historical water mills, some converted into shops, which can be interesting for families.
The Azores generally have a mild climate year-round. However, for the best hiking conditions and to fully enjoy the lush landscapes, late spring to early autumn (May to October) is often recommended. During this period, the weather is typically warmer and drier, making trails more accessible and views clearer. Be prepared for occasional rain showers regardless of the season, as the islands are known for their changeable weather.
Yes, you can! The Prego Waterfall is known for its bathing opportunities, so bring your swimsuit. The Blue Pool also offers an ideal setting for relaxation and swimming in its clear, blue waters. Additionally, the Terra Nostra Thermal Pool provides a unique warm, mineral-rich bathing experience, though be aware the water can stain light-colored swimwear.
Given the changeable weather in the Azores, it's always best to dress in layers. For cooler months or any time of year, waterproof and windproof outerwear is advisable. Comfortable, sturdy hiking shoes with good grip are essential, as trails can be slippery or muddy, especially near waterfalls or after rain. If you plan to visit thermal pools, bring dark-colored swimwear as the mineral-rich water can stain.
While many outdoor areas in the Azores are generally accessible for dogs on a leash, specific regulations can vary for protected natural monuments. It's always best to check local signage or official park websites for the most current rules regarding pets in areas like Parque Natural da Ribeira dos Caldeirões or around crater lakes to ensure a pleasant visit for everyone.
Visitors frequently praise the stunning natural beauty, from the very nice Prego Waterfall and its scenic trails to the exciting bubbling and steaming geothermal activity at Furnas Caldeiras (Hot Springs). The tranquil atmosphere of places like Lagoa do Congro and the unique experience of bathing in the Terra Nostra Thermal Pool are also highly rated. The blend of natural scenery with opportunities for hiking and relaxation is a major draw.
Yes, some natural monuments offer a glimpse into the region's culture and history. At Furnas Caldeiras (Hot Springs) and Furnas Lake, you can witness the traditional 'Cozido das Furnas,' a stew cooked in the hot earth. Parque Natural da Ribeira dos Caldeirões features old water mills, some of which have been preserved or converted, adding a historical dimension to the natural landscape. Furnas Lake also houses the Chapel of Nossa Senhora das Vitórias.
The duration of your visit depends on the specific monument and your activity. For a quick stop at a viewpoint or a short walk, an hour might suffice. However, to fully experience places like Parque Natural da Ribeira dos Caldeirões or to hike around Furnas Lake, you might want to allocate half a day. A visit to the Planalto da Achada on Pico Island, with its extensive trails and numerous lakes, could easily fill a full day or more for avid hikers and nature enthusiasts.
Many natural monuments themselves offer spectacular views. For instance, the trails leading to Prego Waterfall provide scenic vistas. The volcanic landscapes, especially on the Planalto da Achada, offer expansive panoramic views of ancient forests, lakes, and the surrounding terrain. Many of the crater lakes, like Lagoa do Congro, are natural viewpoints in themselves, nestled within dramatic volcanic formations.
