If you have limited time at Baku totally prefered to take a trip to Gobustan . Rare view - orijinal , active volcanos will make you surprise . You can touch muds take a return to open air museum and perfectly desined 3D Bio Museum . Professional and certificated tour guide will give you fully information from past till nowadays . Mostly preferred to take this trip on morning hours so after lunch you will finish your trip so 2nd part of day you can take a chance for another trip or exploring the city centre .
