There have been quite a few enquiries on this forum on the pricing and availability of day trips from Tossa.
The following are examples of prices of tours taken from the Travel Agents in the town – Thomsons and other operators, and hotels, may have their own tours at better prices.
Examples (child price in brackets)
Barcelona and Montserrat €40 (€26)
Barcelona Nou camp €43 (€29)
Barcelona free day €23 (€14)
Barcelona Gaudi €32 (€21)
Port Aventura €49 (€42)
Certainly for trips to Barcelona it is much cheaper to get the bus to Blanes, via Lloret and the train to Barcelona and the journey will be far more interesting.
