This is one of the most, if not the most, famous landmarks on Central Park. It has appeared thousands of times in the movies and television and it’s a much visited area. The view from there is gorgeous. I recommend you to get on the bridge beside it and take a look from there: you’ll see the fountain, the lake, the trees, the city in the background and the boathouse.
The Bethesda Fountain and Terrace were renovated a few years ago and the result has been amazing. Don't miss taking a look at the beautifully restored tiled ceiling under the terrace. As an added bonus, there are often violinists or other musicians that play music under there, the echoes are fantastic!
