2 - 3 litres of water is included in the trip, per person, per day. Additional drinks, like soft drinks, additional water, and alcohol, are not included. We will provide water on the bus to save on the small plastic bottles, so that you can fill up from there (bring your own water bottles). Additional water is around $1 - $1.50 per litre. Sodas are around $1.50 - $2. We also suggest you bring filter water bottles so you can fill up as you go from taps.
