In the morning, head to Danau Singkarak. If you think you want to spend the day around the lake, make sure you bring your lunch with you. Be prepared to get your feet wet walking through the marshes and swamp forest for about 20 minutes before returning to the solid ground of the primary forest. The hike from the camp to the lake takes about 1.5 hours. Make sure to remind your guide to show you any orchids and Nepenthes pitcher plants along the way, and keep an eye (and ear) out for singing Siamang gibbons, which usually start their calls between 8am and 9am.
Explore the area around the lake once you arrive. Be on the lookout for any wildlife cooling off with a swim or taking a drink.
For the rest of the day, it’s your choice whether you explore around the lake, continue on to Danau Sakti (another 3 hours one way), or return to the forest and marshlands closer to camp. You could also make an attempt to reach the ridge trail at Gunung Kapur to the west. Make sure to pack enough food and flashlights in case you don’t make it back to camp before dark.
In the evening, take another night walk before heading to bed.
