Some tips for traveling to Indonesia

If there is something, in addition to the climate in Indonesia, that you have to take into account when it comes to knowing what is the best time of year to travel to Indonesia, it is when is the end of Ramadan.

Every year the month in which the end of Ramadan is celebrated changes, which coincides with the high season in Indonesia.

This is due to the large number of trips in the country, making flights and accommodation very expensive.

Also the end of Ramadan is usually a vacation time in the country with the largest number of Muslims. This means that the places tend to be much more crowded, it is even possible that in some places it is really difficult to find accommodation.

During our first trip to Indonesia we could see that it was inconvenient in terms of planning and prices, but on the other hand, we enjoyed some parties and celebrations that we would not have known otherwise.
