If you want to see the Blue Fire and the sunrise, you should set off early. The gates open at 2:00 a.m., and you can begin the climb up Ijen. It's about 4 km to the top and 600 meters in elevation. The path is wide and well-maintained, with some steep climbs. You'll definitely need a headlamp. Then you can descend into the crater to see the natural phenomenon known as the Blue Fire, which is caused by the combustion of sulfur gases. The path is rocky and requires some surefootedness—but I found it manageable in sneakers. The fire wasn't big when I was there, but it was still fascinating! You definitely need a mask, as it smells strongly of sulfur down there! Masks and headlamps are available for rent. Afterward, you climb back up and can watch the sunrise. You need a bit of luck, as fog often rises from the crater, and you can't see much. Truly beautiful, BUT it's a mass event! Many of those who climb up, and especially those who descend into the crater, don't have the fitness for it, and especially not the surefootedness. So, you have to set off right away at two o'clock! People are also crowding around the blue fire.

Gili Air, the second largest of the islands, offers a bit of Gili Trawangan and Gili Meno - nightlife and quiet places for undisturbed relaxation. Here you can also dive with one of the local diving schools or you can rent a snorkel and explore the underwater world around the island yourself. Diving on Gili If you don't want to be on the beach, you can pay one of the local diving schools and go on an excursion to the local sea depths and believe us, you won't regret it.

The smallest and quietest of the 3 Gili Islands. No cars, just a few R-scooters. Otherwise you get around on foot or with a bike that is not very roadworthy 😉 Alternatively you can take a small horse-drawn carriage. Very quiet and relaxing. Unfortunately, there were a lot of jellyfish in the sea when we were there 🙄

The water garden complex 'Taman Tirtagangga' was built in 1946 by the last Raja of Karangsem, inspired by the spring, cool climate and scenic beauty. The water from one of Tirtagangga's natural springs is considered sacred. The garden is intended to ensure the safety of the sacred place and create a place of reflection, peace and joy for all visitors. In 1963, the Gunung Agung volcanic eruption almost completely destroyed the garden. Tirtagangga is abandoned and subject to looting. The restoration of the water garden began in 1979, but in the 1990s the facility fell into disrepair again. End of the 20th century Widoere Djelantik, the grandson of the last Raja, founded a foundation with the aim of restoring and developing the garden based on the Balinese Hinduism-Buddhism concept. This concept divides the cosmos into Bhur, Bwah and Swah. Swah is the upper world of gods, Bwah is the middle world of humans and Bhur is the underworld of demons. The transition between these worlds is expressed by the 8 sculptures in the meditation center in the northwest corner of the garden. The human struggle between gods and demons is symbolized by 20 sculptures in the Mahabharata pond. https://www.tirtagangga.com/ https://tirtaganggabali.com/index.php/en/home/

In the Mahabharata Pond in Taman Tirtagangga, Pandawa and Kurawa figures rise from the water, symbolizing the human struggle between gods and demons. A path between the statues allows visitors to walk on the water and cross the Mahabharata pond while observing the Pandawa and Kurawa figures. https://www.tirtagangga.com/Sculplan.htm#Mahabharata Excursus: In the Mahabharata, the Hindu epic, the Pandavas are the five sons of Prabu Pandu Dewanata, who rules the kingdom of Hastinapura. King Pandu leaves the kingdom to live as an ascetic, leaving his wife, five sons and the kingdom to his brother Dretarastra. When the five sons grow up, the kingdom will be handed over to them. Dretrastra has 99 sons of his own, called Kurawa. Over the years, Dresastra and the Kurawa try to get rid of the Pandavas and seize power. The disputes ultimately lead to a war, which the Pandavas win despite losses. https://artsandculture.google.com/story/the-pandava-unit-pengelola-museum-seni/NgWB8o4lv7-hgQ?hl=en

Indonesia's lakes are incredibly diverse, ranging from vast volcanic calderas like Lake Toba to mystical crater lakes such as Lake Kelimutu, known for its changing colors. Many also feature unique geological formations, clear mirror-like waters, or are integrated into local spiritual practices with temples built upon them, like the Ulun Danu Beratan Temple on Lake Beratan.
Yes, many Indonesian lakes hold deep cultural and historical importance. For instance, the Pura Tirta Empul Water Temple is a sacred site where Balinese Hindus perform purification rituals in its holy springs. Similarly, the Tirta Gangga Water Palace, though a man-made water garden, was built by a Raja and is considered sacred, reflecting Balinese Hinduism-Buddhism concepts.
Several lakes and water attractions in Indonesia are family-friendly. The Tirta Gangga Water Palace offers a beautiful recreation park with water basins and ponds. The Ulun Danu Beratan Temple on Lake Beratan is also a popular and accessible destination for families, offering cooler temperatures and picturesque views. Additionally, the Pura Tirta Empul Water Temple is open to visitors of all ages, though purification rituals are for those who wish to participate respectfully.
You can enjoy a variety of outdoor activities near Indonesia's lakes. For hiking, there are easy hikes around places like Ubud, which often feature rice fields and natural scenery. For cycling enthusiasts, there are gravel biking and MTB trails available. Adventurous trekkers can undertake multi-day hikes to reach high-altitude lakes like Segara Anak within Mount Rinjani's caldera.
Yes, Indonesia boasts several lakes renowned for their extraordinary clarity. Labuan Cermin Lake in East Kalimantan, aptly named 'Mirror Lake,' has water so clear it perfectly reflects its surroundings and features unique dual layers of fresh and saltwater. Paisu Pok Lake in Central Sulawesi is another 'mirror lake' where you can clearly see the bottom, including rocks and tree branches.
Indonesia, being part of the Pacific Ring of Fire, has many lakes with volcanic origins. Lake Toba in North Sumatra is the world's largest volcanic lake, formed in a massive caldera. Lake Kelimutu on Flores island is famous for its three crater lakes whose colors mysteriously change. The Ijen Crater also features a stunning turquoise acidic lake within its caldera, known for its 'Blue Fire' phenomenon.
Generally, the dry season (May to September) is considered the best time to visit most Indonesian lakes, as it offers clearer skies and more stable weather conditions, ideal for outdoor activities and sightseeing. However, specific lakes might have unique considerations; for example, the sunrise view at Mount Batur and Lake Batur can be enjoyed throughout the day, not just at dawn.
Yes, some lakes are known for their unique ecosystems and wildlife. Lake Sentani in Papua, for example, is home to diverse marine life, including unique species like cork fish, Sentani sharks, and saw sharks. The surrounding forests of many lakes also host various bird species and other terrestrial animals, offering opportunities for nature observation.
Lake Poso in Central Sulawesi, Indonesia's third-largest lake, is unique for having white sand surrounding its edges. This gives it the appearance of an inland beach, where visitors can explore by motorboat and observe the daily activities of local fishermen and fish farmers.
Segara Anak Lake is a stunning crater lake nestled within the caldera of Mount Rinjani in Lombok. Its name means 'Child of the Sea,' referring to its striking blue waters. Formed during a massive volcanic eruption, it's part of the Gunung Rinjani National Park and offers spectacularly beautiful scenery, often reached by adventurous multi-day treks.
Yes, Lake Kelimutu on Flores island is famously known as the 'Three-Colored Lake' because its three crater lakes mysteriously change water colors, often appearing red, blue, and white. Another example is Weekuri Lake in Southwest Sumba, a crystal-clear lagoon connected to the sea, which results in dynamic color changes in its bluish-green waters.
