We are travelling backpack and plan to sleep mainly in campground when it is possible. We are planning to make a loop on the west coast and finding campgrounds along the way from San Juan, to Rincon, to Ponce and back to San Juan. We also plan to spend some time on the Culebra island.
We would be in Puerto Rico from March 5th to March 15th 2014.
For this route, do you think it is necessary to reserve in advance?
