To guarantee sunny days and full lagoons, the best time to visit is between June and September.

The rainy season in Lençóis Maranhenses runs from January to June, peaking between February and May. It is precisely during this period that the lagoons form and the landscape transforms into the paradisiacal setting that enchants our guests.

Put your bags down, breathe, and slow down — there’s no need to rush here.
We suggest a stay of at least 4 nights to fully enjoy OIÁ Casa Lençóis and all the experiences the destination has to offer.

However, some activities are more suitable for children from 5 years old, or for those who already know how to swim and are able to short walks.

Yes, the transfer is private and takes approximately 3 hours and 30 minutes. It can be done in a 4×4 vehicle or van, depending on the number of guests.

It is important to note that only 4×4 vehicles can reach OIÁ. If the journey is made by van, a transfer will be necessary at Santo Amaro square, where the final stretch (about 10 minutes) is completed in a 4×4 vehicle.

Due to the nature of the region, access to our property is only possible via 4×4 vehicles. If you are not in a vehicle with this configuration, please inform us so that we can arrange your safe arrival from the city of Santo Amaro to OIÁ Casa Lençóis in our 4×4 vehicle.

In our bungalows, we have side-by-side bedrooms, but they are not adjoining.

With the buyout option, where the entire property is reserved, we can accommodate a group of up to 23 guests.

Because we are in a natural and preserved environment, it is possible that some insects may appear during your stay — it’s part of the experience in the region. We take all necessary precautions to ensure maximum guest comfort.

To ensure a comfortable and relaxing stay, we recommend bringing light and comfortable clothing, such as swimwear, shorts, bermudas, UV-protective t-shirts, and cool dresses.
The winds are strong during the excursions, so we suggest bringing caps or hats with ties and scarves to protect your hair.

There’s no need for sneakers: the sand on the dunes doesn’t get hot, and it’s best to walk barefoot.

Don’t forget to pack: Insect repellent, sunscreen, and sunglasses.

OIÁ Casa Lençóis is located in an area further from the city center, a few kilometers away. This location is, in fact, one of our most special features: we offer guests a tranquil retreat, surrounded by nature and far from the urban hustle and bustle.

Our staff speaks other languages ​​to assist guests.

We have two bilingual managers on the team, able to assist in English. The other staff members are local residents and do not speak other languages.
