When is the best time of the year to climb Mt Rinjani, and when does the park close?

The best season for climbing is April through December. Mt Rinjani National Park closes from 15th of January to March due to heavy rains during the monsoon season. In fact, almost all year round it is possible to trek due to the tropical climate that Lombok has, unless the volcano on Mt Rinjani has been unusually active. The National Park authority will send us notifications about the current activity level of the volcano, so we will keep you apprised of any changes in volcanic activity as needed.
