Tried Cosol Tours based on previous reviews and was not disappointed in any way.
Had Yellowbird as guide and he did an outstanding job.
Positives: tasted local foods, tons of infomation about the island, first experience with a volcano, bananas straight from the trees, the beach between the Pitons mountains is just unbelieveable, waterfall perfect, and the list goes on and on.
And all this for just 65 bucks. Had to give the man a tip, it was the perfect excursion.
Negatives: Not enough time, cruise ship with 4,000 guests wouldn't wait for us.

We just went on a cruise for our honeymoon earlier this month and went on Cosol Tours in St. Lucia - This is the BEST tour you could possibly do!!! We had such a blast!!! Cosol himself was our tour guide and he was fantastic. He took us to all the scenic parts of the island...made us a breakfast of all local food, took us to a banana plantation, swimming between the pitons...all the while we had free beer, spiced rum, and rum punch! We had such a great time and because of Cosol this was my favorite island on the cruise by far! We loved him!

St. Lucia, awesome place! We were on a boat cruise two weeks ago and out of the five ports we visited, St. Lucia was the best. We had a tour arranged with Cosol Tours.......... what a tour, what a guy? We had a fantastic time........ tour operator was friendly and funny -- had us all laughing all the way. My cheek bones were hurting. We visited a number of places including the volcano, banana plantation and took a water taxi to a beach. Lots of the local food to eat and drink..... yes we had a "mobile vehicle" following us with cold drinks to quench our thirst at every photo stop...yep, ever 10 minutes we stopped to take pictures. St. Lucia is really nice ---- the winding roads were scary at times but the drivers surely know how to handle the roads.... we were safe, praise God. Overall Cosol Tours entertained us and fed us very well throughout the tour. I would recomend Cosol Tours if you want to Tour St. Lucia. I surely hope to do this again. Francis, if you are reading this review, we thank you again for a wonderful time. So you know, the marriage has to be void because I understand you are related (laugh).............. can't marry into your own family (laugh). Thanks again and continued blessings!

This tour was amazing because not only was it super fun, but it was entertaining and edducational. I would definitely recommend Cosol's tours to anyone who wants to tour the island of St. Lucia.
