We went to Playa del Carmen in 2001. I have always wanted to see Sian Kaan. We rented a tracker from our hotel and we took the trip all the way down to Punta Allen. The road was so full of potholes and nothing but curves. It took us alot longer than we thought it would. We were running out of gas, but still could not see any little town. We drove, curve after curve, nothing in sight. Our gas tank was getting low and we were getting nervous. But, luckily, we came upon Punta Allen. It was beautiful and a welcome site. We watched from the pier as lobster cages were put down to catch lobsters. We were able to get gas there through a hose from a local resident. We did not find an actual gas station, but there was gas as the resident sucked on the hose and then filled our tank. We stayed there to eat in a local house/restaurant with two tables. It was the best fish and lobster I ever ate in my life. I wouldn't trade that memory for anything. Sian Kaan was beautiful and even though we were a little nervous because we were getting low on the gas, it was still an adventure I will never ever forget. We stayed in Punta Allen for about an hour and then begun our trip back to Playa del Carmen. We didn't arrive back at our hotel until after 9pm at night, but we had the trip of a lifetime! I want to go back someday, I want to stay at a little hotel and spend a few weeks just soaking up the beauty. My husband and I loved every minute of this trip, even though it was a little scary at times being alone and no place in site. I would never venture that trip alone. We are finally retired now and able to spend more time traveling. We will defintely go back to Sian Kaan again.
