TIPS FOR A GOOD DAY OUT
(1) Be prepared for the bus to be late. Apparently 5-10 mins is common (although I was only told this by another tourist), but we waited exactly an hour. There was a lot of confusion about whether we'd missed the bus, and Viator didn't communicate with us (even though they have all our contact details from the bookings - and an app).
(2) Take plenty of water and snacks in a backpack. There's nothing much to buy at the start of the trail (just a couple of vending machines, but I put 2 euros in and nothing came out). Take at least 1 litre of water per person for the walk. They told us there'd be a 'picnic area' on the trail, but it turned out that it's at the end, just before you get back on the bus. You need to keep your energy up, and hunger would be miserable. The picnic area features a series of catering huts where you can get good street food, beers, juices etc and it's not expensive. Plenty of seating.
(3) Toilets ARE a problem. It was a 1-hour wait at the bus stop for us, and over an hour on the bus. Then a very quick toilet break but only AFTER a brisk 20-min walk. Then nothing for about 3 hours. No going behind a bush on the trail - it's all CCTV-monitored. Then there are toilets at the end of the walk.
(4) The pace throughout is fast. On the way from the entrance to the start of the trail, I could barely keep up (and I'm 6' with long legs). On the platforms, you just have to keep moving. If you stop to take endless shots with your DSLR, you will be very unpopular. Snap a smartphone image when you can.
(5) It can be windy up there. Be careful of spectacles, mobile phones, etc.
(6) Be respectful. We were in a group, but there were independent visitors who wanted to move faster and would barge past with no warning - having someone push past you, when you're on a trail 50cm wide, 100 metres up, isn't fun.
(7) It's quite a long trudge from the start of the trail to the start of the high platforms, and an even further trudge to the picnic area (where out bus was waiting for us). Decent footwear is a must - glad I took my hiking boots.
