We took the full day tour in April. In generally it was ok, but... I expected a little bit more of walking in the national park. Basically it was just walking 50 -100 m from the bus and than back. If I could do it one more time I would choose the half day... the lagoon and the Los Hervideros is nice, but nothing extraordinary this were the first two stops. Then we went a bit more to to the national park, via Janubio salt pans but we did not stop there. In the park we went for the optional camel ride 6 EUR/person, and it was truly the highlight of this tour, it was a real fun and experience, I recommend all to take it. After this the bus took us for the wine tasting, the area was lovely, but there was nothing to do, they offered us a little really very little amount, and only one of the dry or sweet wine sample to taste, there was a souvenir shop and thats it. After this the driver took us for lunch in Yaiza, either you could take a lunch in a local restaurant buffet for 8 EUR, it was goof but again nothing really special or you could take your time there, stop was there around 45 -60 mins. After lunch the guide took us again to follow the Route of the Volcanoes. That was really something extraordinary, unfortunately we could get out only in the area of the restaurant and all the rest of the tour was done as a sightseeing bus. To be honest if the last part would not happen, I would be really disappointed. If I can recommend, I would take only half day tour or some other tour where there is more walking in the park.
