Celestún is a small fishing town on the Gulf of Mexico coast, about an hour and a half west of Mérida, and the gateway to the Ría Celestún Biosphere Reserve. The reserve is a long, shallow estuary where salt water and fresh water from underground springs mix, creating a rich feeding ground for American flamingos. Between roughly late autumn and early spring they gather in large numbers, and a boat trip takes you close enough to watch them wade, feed and take off in a rush of pink. Along the way the boatman will steer through a tunnel of mangroves, past pelicans, herons and ibises, and stop at a freshwater spring called a ojo de agua where you can swim. The tour usually finishes with a fish lunch at a beach restaurant and some free time on the sand. It is a gentle, rewarding wildlife day with very little effort, and it is particularly good for families and for anyone who wants a break from ruins.
Listing details: the day tour from Mérida lasts about seven and a half hours and includes an air-conditioned vehicle, a guided nature tour of the biosphere reserve, a bilingual guide, beach facilities such as loungers, showers, a pool and hammocks, and lunch. Entrance fees are covered, but travellers are asked to bring about 500 pesos in cash for the visitor centre and boat operators, which is easy to miss when comparing prices. Hundreds of travellers have reviewed it, with a high rating and free cancellation up to a day before.
Seeing the flamingos: numbers and positions vary with the season, tide and weather, and the birds are wild, so the boat keeps a respectful distance. The best months are generally from about November to March, though some birds can be seen at other times. Go in the morning when the light is soft and the water calm, wear sun protection, bring a hat and binoculars if you have them and keep your voice low. Do not attempt to feed or chase the birds, and follow the boat captain's instructions.
Making a day of it: Celestún town is simple, with a beach, seafood restaurants and a quiet main street, and the Gulf waters are warm and shallow. If you want more time, stay overnight in a small beach hotel and see the flamingos at first light. On the way back to Mérida you can stop at a hacienda or a roadside cenote. It combines well with a visit to Uxmal on another day, and it is a relaxing counterpoint to the ruins.
