The buses are sufficient. All buses spoke out from Fira. So you can’t go from town to town. You always have to go to fira. To see more of the island you can rent a car or a 4 wheeler or a scooter. We did okay with the bus system. The buses run regularly and are air conditioned and cheap. You may want to rent something for a day or two to really move around the island. It’s not that big so we did well with the bus system

I believe so, but it all depends on your fitness level, we did it from Fira to Oia up to the red bike restaurant. I've recorded teh whole trail with strava and i can tell u Fira to Oia you have a elevation gain of 470mt and a loss of 670 mt so over all you going down hill. The opposite way you will have to climb more and in Fira theres not many taxi to just jump on if you are too tired to walk back.

Sorry no, none at all. The trail is along the caldera (cliff) side of the island so no beaches to be found. But amazing views!

No conozco el frances... pero creo que preguntas por el mejor horario. La mañana sin duda!

Yes it can be done all depends on your walking skills and fitness. The walk can be done in 1h 15min to 3h max this is by taking your time with photos and numerous brakes.

Make that 550m from beginning paved trail to parking lot. (not 5500m).

There are a few stores here and there, but you can’t rely on them being open. That said, we didn’t complete the hike. So I would ask others.

Hi , yes you should be ok with a pair of sneakers... you mean trainers right?? No flip flops, Sandles or high heels, closed shoes, to protect your toes. No crocs either...

I would suggest walking downhill from Imerovigli to Fira rather than doing the whole hike from Oia to Fira. We took the bus from Oia going towards Fira and when we boarded the bus we asked the driver to let us off in Imerovigli which worked out well, walking down hill to Firostefani and then Fira.. We took the bus back from Fira to Oia.
