From the main road it is a really easy walk in and so pretty. You do not need a guide at all, the walk is about 10 minutes. We used a guide because we didn't know and because we had a vehicle with us and $40 XCD seemed like a good insurance policy.
There are two sets of falls the farthest in are the highest. You can walk under them . Just be careful, obviously, the water flow changes all the time. At times the pressure was very intense.
The lower falls you can slide down and into a warm pool of water. The slides you want are on the right hand side. Be brave, you will be glad you did.
Definitely a highlight of our time here.
