Try to eat at the privately owned restaurents, the state owned are very montonous as it seems that the same supplies are sent to all the hotels.
Good walking boots, a head torch and a damp flannel or wet wipes are essential for the bunk house stays. There was NO water available at Aguada de Joaquin apart from that which is provided for drinking.
Pack all your stuff into waterproof bags / bin bags for the pico turquino trip, it is very humid & everything gets damp even if it doesn't rain.
Take an additional small, light waterproof bag big enough for both your fleece & sleeping bag which will be carried by the porters. My sleeping bag was wet with sweat from one of the porters, not very special!
The Pico Turquino day is tough. We had ideal conditions & it still took longer than stated. we started in the morning at 6.50, lunch at 12.15 - 13.15 , arriving at la Platica from 15.25 - 16.45. A total of 9 hours hard slog. 3 of the group decided to go straight to la platica & one did not make it to the top of Pico Turquino.
When descending from Pico Turquino, take the second sign to la platica, it is after the car park as the first path is extremely slippery, even when dry & many of the steps are missing.
Take plenty of energy bars, dried fruit, nuts from the UK. Children appreciate biros and sweets. The guides have equipment mainly donated by travellers & will appreciate anything which you can spare. Take old clothes and shoes if you have room in your case, they will be much appreciated as the state does not provide clothes & they are very expensive for the Cubans to buy.
You need to be fit for this holiday, it is probably not suitable for anyone who does not take some form of regular exercise.
The itinery is a good balance of walking & sightseeing. We drove 2,600k but because it was well paced with interesting stops it never felt like we were in the coach for too long.
