Take the MRT to the Bayfront Station. While there are admission charges to the two domes and skywalk, the rest of the park is free to roam. I would recommend going at dusk to see the sunset and hopefully dramatic skies as we did. The light show, choreographed to music, starts at 8 but get to the base of the supertree grove early for a seat. You also get a great view of the Marina Bay Sands hotel.

We loved this place! So beautiful, well designed, immaculately tended. We're not gardeners but really enjoyed our visit here. We didn't go into the greenhouses / domes as it was so hot. We fancied a gentle stroll instead. So we walked around the paths, alongside the lakes etc where we saw otters, various types of birds and lizards. All this was free of charge. We then paid $8 to go up onto the skywalk. That was well worth it. Spectacular views. A fun experience. Overall Gardens by the Bay is a lovely idea. Every city should have a garden area like this. Somewhere to while away an hour or so and get some respite from life's hustle and bustle. I would highly recommend this attraction to anyone of any age.

Really a must see as there is not that much to see in Singapore. You can walk through the park without charge, only the elevated walk and the buildings have entrance fees.

This was probably the highlight of our trip. The Cloud Forest was unbelievable, and the light show with the supertrees was awesome!
