Intercity transport on the island is weak here so the best idea is to rent a car and go… You can rent a compact car for 26 USD/day but take care about hidden costs: insurance, one-way rental, taxes. Only best agencies like AVIS will show them when you book via internet.
I started with my companion from San Juan early in the morning. We went to the mountains to enjoy the landscapes of the lush green interior covered by the thick forest. Roads are good here, but in the mountains they are narrow. Nature is graet: fern trees, palms, breadfruit… In the stalls on the roadside you can buy bananas (10 for 1 USD) or nice papaya for 2 USD…
We visited little and charming colonial city of San German… and after some 10 hours we arrived to Ponce – second large city of Puerto Rico with rich historic output.
Petrol is cheaper here then in Europe: 87 cents per litre.
I am sweaty and tired but happy after such an interesting day.
