I did like the price for the areas we visited, cause there were different locations. It was around 20 euro per person. The only thing is we did not have enough time to walk in island. The boat trip took 45 mins , instead of 25 (this promised me the manager on the phone. Side note: if I knew the correct time frames I would probably rejected trip due to my motion sickness). So it started at 14 00h and finished at 17.00. We arrived at 14.45 and the story telling from guide took too long (so the other tourists complained too). We had only 30mins to go and back on the track to the fortress. We didn't get time to see the fortress on the water, we barely managed to reach boat on a way back, when we came at 17.05h. The guide telling was interesting and in good pace(speed), no complains for the guide, but the time for tourist walking ourselves should be prolonged.
