Nightlife in this rural wine region is restricted to the wine bars of the local bodegas and the small hotel bars, all of which are family friendly.
I recommend an evening at the high quality Stratvs Bodega , having dinner in the restaurant, followed by some sampling of the excellent wines at the bar. The bodega and bar, El Chupadero (La Geria 3; +34 928 173115; www.el-chupadero.com) regularly has live music events and even DJs.
La Geria is in Lanzarote. For general advice on nightlife in Lanzarote, see my Lanzarote nightlife page.
