The Gruta da Lapinha is part of the Parque Estadual do Sumidouro, which offers a range of…read moreattractions inside beautiful nature. The main attraction is the cave system, which is accessible through a guided tour. There is also a nice museum and some great hikes. It is only about 45 minutes to an hour out of Belo Horizonte, so it makes for a perfect day (or half day) trip.
The cave is easily accessible for anyone and quite pretty. There are great calcite formations (stalactites, stalagmites) that the guide will point out to you. To keep kids entertained the guide may point out some formations that look like animals. The walking surface has been smoothed out a bit, and there are stairs to get you from one 'room' to the next. Some lighting shows the way and highlights the formation; all reasonably modest and not overly dramatic. In the cave it is nice and cool (not so cold that you'd need a jacket). Closed-toe shoes are nice but not absolutely required; the park will give you helmets as the ceiling can be sometimes a bit low.
In front of the cave there is a very nice and shaded (grassy) park, which is good for picnics. The museum is small but interesting. Not all explanations are in English, unfortunately, but there is a lot of interesting information about speleology, archaeology, paleontology, and cultural heritage. The oldest human fossil of the American continent (named Luzia and dated at 11,500 years) was found in a cave in this region. There is some good info, also in English, on this discovery and its context.
A few kilometers from the cave is a separate visitor area of the park that focuses on the early explorers (bandeirantes) and the large sinkhole (sumidouro) after which the park was named. You buy tickets at the cave and then drive about 8km to the start of the (guided) hike l. There you will be treated to beautiful limestone outcrops, great vistas, and amazing prehistoric rock art; the oldest of this has been dated to about 7,000 years. When we visited, we noted there are some additional hikes through the park, such as the 'travessia' from the Gruta to the Sumidouro.
Oh, and English guides are available, but it may be best to call ahead!
