You find Lake Batur on the road north from Ubud. This immense body of water at the foot of the Gunung Batur volcano is a rather important attraction in the area where you can do all kinds of outdoor activities: climbing, hiking, mountain biking, and water sports in the lake. The view of the mountain is beautiful, but sometimes it can get a bit foggy. But, even if you're there on a gray and foggy day, the panorama is worth it. I was lucky that day and it was clear out. To get there, you can rent a motorcycle in Denpasar. The road to the lake and the volcano is lovely, and has many rice fields, temples, etc..
Lake Toba is a small lake that is inside a crater of a volcano on the island of Sumatra. Within this lake there is a small island that is beautiful to rest on for a couple of days if you travel or just selecting Sumatra as a tourist destination because you will explore a small piece of the heart of Sumatra. It is an amazing feeling being on an island within an island. I recoomend to stay at one of the many hotels you can find in the village of Tuk tuk, the island resort. In any hotel or guest house the people there will tell you the best options how to visit the island. There are also some interesting natural hot springs, and small towns where local people match surprises for your kindness and curiosity. It is also worth to make a visit at the Indonesian traditional houses in which you can enjoy its architecture. Do not forget to enjoy the sunsets, that are very similar to the ones in Ecuador and are just very beautiful.
Lake Bratan is the second-largest lake on the Indonesian island of Bali. It's over a thousand feet high and is a volcanic crater which has filled up with water. To get there, you need to catch a minibus leaving from Ubud or the coast. On the road, we went down to see monkeys at the temple dedicated to the goddess Dewi Danu. You can go visit by boat or from your hotel or directly by bus if you're arriving from another coastal town. I arrived at the hotel in low season when it was almost empty and there was no staff. I even had to use the hotel's kitchen to cook my food, but I didn't mind. You can negotiate the price of the stay, as well. Usually, it's the high-end hotels that give good deals, not the basic ones, but you can get a good room for a few dollars more than a hostel. The lake is very quiet, and surrounded by friendly people and delicious food. It's perfect for a relaxing break before heading off for a new adventures. Many people come to Bali just to see the beaches, but the interior has its charm too. The road up to the lake and the crater is beautiful. I came from Ubud, and then went down to Lovina. A night on the lake will cost around 5 euros or 8 for a couple. It's almost always cheaper to get a room for two than for one.
After visiting the touristic Danu Temple, beautiful, yes, but it remains a magnet for visitors and a "must" when visiting Bali, I recommend following the road which leaves from the car park and moving on. When you spot a beautiful stretch of water, in a quiet and peaceful location, stop the car. That's Buyan. The water of the lake reflects the mountains which amateur hikers from around the world have explored, the quiet that seems to permeate the enclave, where not even the water dares to make a noise, it is incredible. Behind you there is a small temple, not as nice as the previous one, perhaps less romantic but also inhabited by water spirits. People come here to fish, to talk or just to spend the afternoon. It reminds me of the alpine landscapes of Switzerland or the close-by country of Nepal. Let's enjoy it for a few, long minutes before continuing ...
The early start was awful, I think it would have been better to stay up and have no sleep, but we were told that the views of the volcano were better in the morning. It is an interesting place though it is hard work to climb, with endless hills but when you get to the top it takes away all the pain because it is beautiful, I was speechless.
Maninjau Lake is one of the most famous and valued natural places on the Indonesian island of Sumatra. Located 40km from Bukit Tinggi but the journey takes just over 2 hours by minibús as it is mountain road. The lake is in the crater of an ancient volcano and so it is uphill on the way there and downhill on the way back. The road offers good views over the lake, and you can ask the driver to stop to take pictures. Like a bus full of tourists! The lake is 15 km by 8km and is surrounded by impressive cliffs 500 meters high. As in Bukit Tinggi, the population in Minangkabaus is muslim but with special traditions. The land and the house belongs to the woman who then leaves it to her daughters. Most people grow rice and have some animals. You can swim and enjoy various water sports and rent a bike to get around the lake (5-8 euros), on not the best of roads. If you want some days off, in one of the bamboo houses for rent at the foot of the lake, Bayur village is quiet and caters for all budgets.
Lake Tamblingan is hidden away between the two lakes that occupy an ancient caldera in the mountains of central Bali. This lake can be reached by a path that starts from Pancasari on the shores of Lake Buyan. The stagnant water isn't ideal for a dip, but if you love walking in the forest and the chance to see a bit of wildlife (especially birds), then you can take a short hike up here. From the road that leads to Munduk and then Seririt there is an excellent overview of both lakes. Not far away is the town of Bedugul and the famous temple Pura Ulun Danau Beratan
