Mount Ramelau, also known as Tatamailau, stands as the highest mountain in Timor-Leste (East Timor), reaching an elevation of 2,986 meters above sea level. It is sacred to the Timorese people and is an important pilgrimage site, particularly for Easter celebrations when hundreds of people climb to the summit for a sunrise service. The mountain provides a habitat for a range of endemic species and offers breathtaking panoramic views of the island and the surrounding ocean. Hiking Mount Ramelau is a challenging yet rewarding experience, typically starting from the village of Hato Builico in Maubisse. The trek can be made overnight to catch the sunrise from the peak. Along the ascent, visitors find a statue of the Virgin Mary, which marks the final climb to the top. The mountain's natural beauty and cultural significance make it a unique destination for both trekkers and those interested in the local customs and traditions of Timor-Leste.
