Adventure
If you are looking for a more intense adventure you are spoiled for choice in Bali. The possibilities for trekking or biking, including mountain biking and e-biking, are limitless, those who love to get wet can go diving, snorkeling or river rafting.
Jungle trekking in the higher areas of Bali, sunrise trekking on one of the volcanoes (excluding Mount Agung which is in an active phase since September 2017. There is still a 4 kilometer danger zone around the crater and it is strictly forbidden to enter this zone.)
Amed is the best dive and snorkel area in Bali. You will find a lot of very interesting dive and snorkel spots like the Liberty shipwreck in Tulamber, the Japanese shipwreck in Banyuning, coral gardens, pyramids with artificeally grown corals or an underwater temple.
The best places for this sport are around Ubud.
Exhausting mountain biking, comfortable e-biking or just normal biking is all possible in Bali. Bikes are for rent in many places and it is a nice alternative to explore the island.
