Just a warning to anyone planning to go on an organized trip from Costa Adeje to Loro Parque - we did this trip last week, booking with Thomas Cook from the Bahia Principe (other excursion companies didn't pick up from Bahia Principe so Thos Cook seemed the easier option.) Before our holiday I had looked at google maps and thought the coach journey would be in the region of 1.5 hours, going by the motorway. Thomas Cook went via Los Gigantes - the start of a hellish journey.
We were picked up at 8.00am and picked up at Los Gigantes about 9.30. We then went over the incredibly winding road over the mountains. I'm a good traveller but felt nauseous - loads of kids on the coach were sick, and of course the rep didn't have sick bags. We reached Loro Parque at 1.00 - 3 hours after we set off!
The return journey was just as bad with kids vomiting all over - it really is a bad journey.
I would suggest if you book this trip that you get ABSOLUTE confirmation of the route the coach will take if your party are poor travellers - this journey could ruin an expensive day out.
