Palace of Knossos is one of those "must see" places. You should understand it is under the construction but it all is mainly broken like all ancient ruins. All the treasures you can see at Archaeological Museum.
At the museum is very illustrative and instructive scale model of the palace. The tickets to the palace are 15€ and to the museum 10€. If you buy a special ticket package which is a combination ticket including both places you pay just 16€ (valid for 3 days) (children under 18 years free) (June 2017).
Michael advised us to go to see also Museum of Ancient Eleutherna. We didn't know it is there despite we've read many guidebooks and articles when planning our holiday on Crete. The museum is accessible also by wheelchair and offers great views around. It is a very modern place to visit despite you'd have some limitations or disabilities. The tickets are 4-2€ (children under 18 years free) (June 2017).
The Ancient Eleutherna is more than the museum. There is still the real Ancient Eleutherna with all the ruins. The museum just holds the treasures.
The area around to the ruins is wide and not accessible by wheel chair (but still worth of driving around by a car to see the old village of Eleutherna where people still live, there you can also wind-up a bit). It includes great walking routes from sight to another. You should not try to bite it all by one visit. It is place where you can go hiking for many times and always to see something new.
We went to see the cisterns.
We didn't have the flashlight with us but it was not necessary. When you stand there by the mouth of the cisterns staring into the darkness for a while your eyes get use to it and adapt pretty soon.
Then you notice you can see more and more and go deeper in despite you have no flash light. Your eyes adapt faster into the darkness than light. It happens even faster if you keep your eyes closed when waiting it to happen. :)
We also drove around a bit and went to see the wider region. Visits to The Monastery of Arkadi and village of Margarites (known from its pottery) are easily connected to Eleutherna trip. In Margarites is a great tavern Mantalos with stunning view.
PS. Tomorrow I will tell you one more story about our CretanHoliday considering gluten free food and eating out as a coeliac in Greece/Crete where coeliac disease is pretty unknown. After that we'll be back to normal craft blogging with few interesting designs and materials I am on at the moment.
