Cuba

I'm heading to Cuba on the 24th Feb for just over 3 weeks.
I plan to see as much as I can, including: Havana, Baracoa, Cienfuegos, Trinidad, and maybe Santiago and Vinales too.
I'd like to spend a few days hiking (day hikes), and a few days at the beach. Anyone have any particular recommendations for nice hiking trails and good beaches (ideally not too touristy)?

I'll be travelling alone, so if anyone has any general advice or recommendations for Casa Particulares, things to do and places to go etc. I'm all ears.

Many thanks,
Matt

1. Learn Spanish if you don't know it already.
   
2. Otherwise, at least learn the words for today and tomorrow because if you want to buy a train or bus ticket, probably you want it for today or tomorrow.
   
3. Casa Particulares are great.
   
4. Waterproof backpack. When it chucks it down, it really chucks it down.
   

"Mobile telephones, tablets and laptops can be taken to Cuba, but any inbuilt GPS should be disconnected or disabled."

Really?

Get some basic salsa lessons before you go.
Trinidad and Vinales have brilliant outdoor salsa sessions in the evenings.
