Being a lot less touristy than Bali, one does get an authentic Indonesian experience. With places like the Gili Islands and Mt Rinjani, there is so much to do for not only surfers but divers and explorers. Why don’t you take a guided bicycle tour? There are some beautiful quaint accommodation options and the beaches are spectacular.
Most of Lombok’s south coasts offer surf-seekers challenging waves of various grades. There are four surf-points, which are highly recommended. Within the Lombok’s Kuta Beach there are two points, namely Gerupuk that provides softer waves, and Aik Guling offering waves mostly for the goofy’s. The ideal surf season is during the periods of June, July, August, December and January. The next break is at Ekas Beach that provides more challenging waves and reef-break-point, reachable by boat or by land from Kuta Beach. Alternatively, choose to stay at the Sanctuary in Lombok.
