Selamat datang! Welcome to Indonesia. The adventure begins with a welcome meeting at 6 pm. If you happen to arrive early, perhaps check out Maimun Palace – designed by a Dutch Architect and built in the 19th century, it combines architecture from Malay, Indian and Islamic cultures and is now a museum. Alternatively, buy a ticket and take a guided tour of the museum at Tjong A Fie Mansion – known as "the historical jewel in Medan", the Tjong A Fie was built in 1895 by a hakka merchant and is modelled on the Cheong Fatt Tze mansion in Penang. After your important welcome meeting, you could head to grab some street food with your group at one of the night markets in town, or go to a local restaurant – your group leader will know of some good spots.

Jump aboard a private vehicle and drive to Bukit Lawang (approximately 5 hours). The first part of the journey involves quite heavy traffic, but the roads are nice and smooth. Closer to Bukit Lawang it gets bumpy and windy, so brace yourself for a bit of an adventure. The reward for the journey is the destination – Bukit Lawang a peaceful village located on the banks of the Bohorok river, right next to the Gunung Leuser National Park. In the afternoon you can take an optional tour in the countryside by becak (cycle rickshaw) or cool off with a refreshing swim in the river. There will be also be plenty of time to prepare for your jungle trek.

Set off on your trekking adventure through the Gunung Leuser National Park with an experienced guide (approximately 5–6 hours). The night will be spent camping out in the jungle. This UNESCO World Heritage-listed park spans 7927 square kilometres and is one of the world's most diverse ecosystems. It's the home of many endangered species, including the Sumatran tiger, rhinoceros and elephants. These animals are extremely rare to see but you will get the chance to go in search for wild orangutans. There used to be an orangutan rehabilitation centre here, but now these creatures have all been returned to their natural habitat, so this is your best chance in Indonesia to see orangutans in the wild. There are also 300 species of birds, and many rare plants and flowers. Today's hike is hilly and can be muddy. The paths are mostly clear, but there are some sections where you’ll have to climb over large fallen logs. You may stop and rest while the guides go in search for orangutans. Along the way, guides point out orangutan nests, edible plants for you to try, monkeys, birds, and wild orangutan. You will carry your own lunch and break for lunch along the way then continue trekking to the camp site, where the guides set up and cook dinner for the group.

You will wake early to the sound of gibbons and continue the trek down river (approximately 2 hours). Your feet may get wet, so strap-on sandals, booties or local rubber shoes are recommended to pack. Head back to Bukit Lawang, where day rooms will be made available for a freshen up and shower before you get on the bus. It's also a good chance to stock up on some tropical fruit for the road. Depart early afternoon for Berastagi (approximately 5.5 hours). Berastagi is the home of the Karo people, a Batak sub-group with traditional villages (long houses), and is your destination for the night.

Drive for approximately 30 minutes to the starting point of today's hike. The hike (approximately 2-3 hours) brings you to the top of Sibayak Volcano (2094 m). It's quite steep, muddy and slippery, especially in the wet season. Follow a shady jungle path which, towards the top, opens up into a more alpine setting. Long pants are essential to protect you from poisonous plants, and a trekking stick will also come in handy. After reaching the top, sit down to a traditional bungkus lunch and enjoy the views. From the summit you can see (and hear) the steaming vapours escaping from the fumaroles of this active volcano. Then it's time for the descent (approximately 1 hour). Afterwards, head straight to the nearby hot springs for a soothing soak – after a few days of trekking, you deserve to relax in these pools, which are all naturally heated by the volcano.

This morning, head to Tongging Village by private vehicle, on the banks of Lake Toba (2 hours). The road from Berastagi to Lake Toba is a nice, smooth road. Then, continue on and stop at Sipiso-Piso waterfall, which was formed by a small underground river of the Karo plateau. Watch as water cascades from a cave in the side of the Lake Toba caldera some 120 metres (360 feet) down to lake level – forming Indonesia's highest waterfall. Lake Toba itself, surrounded by mountains, is a peaceful spot to relax. It was formed by a huge volcanic eruption 70,000 years ago; a second eruption 50,000 years later created an island the size of Singapore in the middle of the lake – Samosir Island. Your accommodation tonight is right next to the lake and boasts nice views of the water, mountains and rice fields.

Embark on a day tour in Samosir. Visit the Stone Chairs and the Simanindo Museum (in a traditional house). You’ll also travel up to a viewpoint on the island which gives you a panoramic vista of the below Lake Toba and the surrounding Sumatran countryside. Walk through nearby rice fields and stop by a local Batak house for a traditional lunch. Toba Island is dotted with many ancient and modern grave sites, several of which you’ll see on today's tour. You’ll also have the chance to enjoy a traditional Batak dance performance. The Toba Bataks have a unique religion, architecture and culture. Although they are predominantly Christian, they also practice animism. The most distinctive element of their culture is the traditional architecture – extraordinary boat-like houses with roofs resembling buffalo horns.

Drive back to Simanindo (approximately 45 minutes). From there, take a boat back over Lake Toba to Tigaras (approximately 45 minutes). Make a stop at a traditional Dokan Village where you'll find a handful of traditional houses which are still the homes of local Batak families. Afterwards, continue back to Medan (approximately 3.5 hours).

Today you will fly from Medan to Jakarta approx. 2.5 hours. Please note you will be unescorted for this flight but you will be transferred to and from the airports. With your free time in Jakarta check out some of Jakarta's interesting museums, such as the Wayang (puppetry), Balai Seni Rupa (fine arts) and Maritime museums. The National Museum is great for first-time visitors. For a city monument, don't miss the Monas (National Monument) dedicated to the spirit of the Indonesian people. As this is a combination trip, your group leader and the composition of your group may change at this location. There will be a group meeting to discuss the next stage of your itinerary and you're welcome to attend, as this is a great chance to meet your new fellow travellers.

Familiarise yourself with the city on a full-day tour with your local guide. Take in Sunda Kelapa port – where the Dutch first landed, temple-filled Chinatown and the old town of Batavia. See Si Jagur – an old Portuguese cannon ornately decorated with a disguised meaning. Visit a Chinese mansion (Chandra Naya) and gain an insight into the beautiful Peranakan architecture. Wander about Fatahillah Square, then explore the religious side of the city at Cathedral Church and Istiqlal Mosque – the largest mosque in South East Asia.

Today there's some distance to cover, so you will spend large chunk of the day travelling. Travel by train to Purwokerto City (approximately 5.5 hours), then take a private minibus to Pangandaran (approximately 3 hours). Pangandaran is a small fishing village popular with visitors looking for a coastal escape. The Penanjung Nature Reserve on the adjoining peninsula boasts some impressive flora and fauna, which you’ll see some of tomorrow!

Set off on a tour of the local surrounds, villages, cottage industries and the impressive Green Canyon. Your day trip begins with a stop at a local market to check out the produce and home industries such as palm sugar and rice cracker production, as well as the famous Javanese wayang golek (traditional wooden puppets). Then you'll continue to the Green Canyon. Hop aboard your boat and travel upriver (approximately 30 minutes) through superb jungle scenery, before stopping for a swim up in the canyon itself. This spot, whose water is as green as its name suggests, is a popular hangout for locals, so take the opportunity to interact. Your day will take you to a nearby beach where you can have a break for lunch and swim in the afternoon before heading back to your accommodation.

Head inland by private minibus (approximately 1 hour) before catching a train to Yogyakarta (approximately 4 hours). This town is one of South East Asia's real gems. It's Java's cultural heart, has a great atmosphere and is an Tuuur favourite. From batik workshops to the nearby Hindu and Buddhist temples, Yogya offers a great array of cultural avenues to explore.

Rise early to avoid the crowds at Candi Borobudur – the largest Buddhist structure on earth. This magnificent World Heritage-listed site is set in a tranquil park. As you approach, you'll see the enigmatic temple rise before you, looming amongst the tropical foliage. With your local guide, follow the route of ancient pilgrims, circling the mandala-shaped structure from the early realms towards Nirvana. It's truly one of South East Asia's treasures. Afterwards, enjoy an afternoon of free time. You might like to visit one of Yogya's other heritage temples – this time perhaps of the Hindu faith. Prambanan Temple is the largest Hindu complex in Java. This evening, perhaps catch a performance of the epic Ramayana Ballet – your leader will be able to check dates and availability for you.

Pedal out of the city on a cycling tour (approximately 6 km) through the rice fields and countryside surrounding Yogyakarta. See the locals in this area making various goods, from bricks to tofu and tempe. As well as palms and lush green grasslands, you will see the odd burst of yellow and pink flowers by the side of the road, which make for great photo opportunities. This cycling tour is on relatively flat ground, so it won't be too strenuous. There will be ample time to take in all the interesting scenes of slow-paced local life. You will then have a free afternoon today and there are many activities for you to choose in Yogyakarta. Perhaps a cooking class to learn about Indonesian cuisine or salute to the sun with a yoga class – there is something for everyone!

Travel by train (approximately 4.5 hours) before transferring on a minivan (approximately 1 hour) to Seloliman Nature Reserve. The peaceful Seloliman Nature Reserve is situated on the slopes of the sacred volcano of Mt Penanggungan. Meet some of the volunteers working at the Seloliman Environmental Education Centre and eat delicious, locally grown organic produce cooked by their staff. The centre's accommodation is atmospheric, even with open-air bathrooms built in harmony with the surrounding forest, so take this opportunity to relax. This is a beautiful spot to appreciate nature – be sure to sit under the stars tonight and take in the ambience of what’s around.

Join reserve staff on a walk around the reserve, learning about the local environment and the Javanese tradition of herbal medicine (approximately 2.5 hours). You'll gain an insight into the region’s flora and fauna, traditional farming methods, rice production and the mini hydroelectricity plant. Finish up with a traditional jamu demonstration and a tasting of this Javanese herbal medicine. Continue on to Mt Bromo – the timeless homeland of the Tenggerese (approximately 4 hours). The still-active volcano – standing at 2329 metres – is the most well-known of the Tengger massif. This region is also the homeland of the Tenggerese and the steep, cultivated hills of the Tengger Valley. Retire early tonight in preparation for tomorrow's early start.

Your early start today (around 3 am) will be well worth it; trust us. First, drive to a lookout point in jeeps for sunrise over the sea of sands. If the weather is clear, the sunrise over this eerie sea of volcanoes is an unforgettable experience. Afterwards descend in your jeep to the sea of sands and climb up to the volcano crater to take a peek inside. The ascent is not too difficult (approximately 45 minutes), but it can be very cold, so don't forget to bring extra layers of clothing. It's also worth bringing a scarf to cover your nose and mouth, as it can get dusty. Return to the hotel to freshen up and then depart midmorning to Kalibaru in a private minivan (approximately 5.5 hours). You'll stop for lunch en route, then arrive in the afternoon, with time to relax by the pool or perhaps indulge in a local massage.

Head out early in the morning to tour nearby coffee and cocoa plantations. You'll see how coffee is dried and if there’s time, how cocoa is fermented. Before you set off, enjoy a nice cup of coffee or tea and snack on fried banana. Travel by minibus to the far eastern end of Java – Gilimanuk (approximately 3 hours). There is often a lot of heavy traffic on this stretch of road as it's the main entry point for Bali, so there may be some delays. Next you'll board a ferry across the Java Strait (approximately 1 hour), before boarding another minibus for a journey along the west coast of Bali (approximately 1 hour). Travel on to Pemuteran – your destination for the next two nights.

Enjoy a relaxing day in this gorgeous beachside location. Maybe start the day with a relaxing yoga class and then explore the local area at your own pace. You could visit the surrounding monkey-filled temples, go swimming off the coast, or think about booking in a snorkelling or diving expedition to the turquoise and marine life-rich waters of Menjangan Island. Otherwise, simply sit back, relax and watch the fishermen go about their day-to-day on one of the beaches.

Make the journey to Ubud (approximately 5 hours). En route, stop in at Taman Ayun Temple, taking in the impressive Balinese architecture while you stroll around the tranquil gardens. Ubud is Bali's main arts and cultural centre – a thriving centre of markets, shops and warungs and close by to verdant rice terraces and lush jungles. With nature and wellbeing at its core, Ubud is a highland haven of Bali. It's a wonderful place to experience the magic that has made Bali such a popular travel destination. Tonight, why not get a group of your travel pals together and find a local place to eat some traditional Balinese cuisine.

Your trip comes to an end after breakfast this morning. There is plenty to see and do if you're staying longer. Hire a bicycle and explore the surrounding rice paddies and small villages, or visit galleries, museums and handicraft merchants in town. If you would like to spend more time in Ubud, we’ll be happy to organise additional accommodation (subject to availability).
