Located just east of Bali, Lombok has been promoted as "an unspoiled Bali" for quite some time, with beautiful beaches and the large, looming volcano of Mount Rinjani. However, an impending tourism boom was severely disrupted by riots in 2000, when mobs of Muslims and ethnic Sasak people, ostensibly protesting sectarian violence in Maluku, attacked and looted churches as well as homes and businesses owned by Christians and ethnic Chinese. The ensuing years have been quieter, but tourists have continued to stay away.
The more Islamic culture in Lombok compared to Bali may explain the reason why Lombok is quieter than Bali in terms of parties and nightlife, which can be either a positive or a negative depending on your point of view. Lombok is also becoming increasingly popular for honeymooners.
