A taxi ride from Cienfuegos (about $22 return, including waiting time) to the entrance, where you can buy drinks and wait in the shade for a guide. An easy ten-minute walk with the guide to the boatshed. Small boats with a hard-working oarsman who takes you across the lake to where you may see lots of flamingos if you are lucky. We were lucky. And if you are still lucky, the guide will show you how to entice a large hairy spider out of a hole in the path.
