Instead of using the services of a tour company, which would cost about 165 USD , we decided just to drive ourselves to San Blas. We left about 630 in the morning and traveled all the way through the Corregidor Sur. For first time drivers, the landmark to look for is the big sign that says, Altos de Llano and immediately after that , there is a left turn going to Kuna Yala . Up to this point, travel time is about 1 hour. Once you make that turn, just follow the road until you reach the end which is the Port Carti Tupile. But be careful, the road is a roller coaster ride with tight turns and some patches of dirt . It would be better to have a 4x4 because of the steep climbs. At about 30 minutes of driving, there is a checkpoint and you have to show your passports or residency cards. You also have to pay 5 USD per person (for residents) and another 5 USD for the car once you reach the port,which is after another 30 minutes you have to go to the blue building and pay another 2 USD per person plus 3 USD for parking. After this , you can meet the boatman of your choice. it is better to pre arrange with a boatman the day before so he will be waiting for you in the port. Otherwise, you can try your luck with those offering services in the port. In any case , cost for the boat is about 30-35 USD per person. Travel to the islands will take about 30 minutes.once you have arrived at an island , the locals will charge you another 2 USD per person , for using their facilities. Be sure to bring your small bills for all of these expenses. The locals will also offer you food like lobster 15 USD for half, or fish 20 USD. I would suggest that you just bring your own food but if you want to help out a bit, better if you order something fom them. There are toilet and shower facilities in some of the bigger island . By the way, the boatman can wait for you so be sure that you do not pay right away on arrival but once you get back to the port. Hope this is helpful to the first time travellers.
