Located inside the Tropical Garden (a very affordable 50baht per person), the waterfall and surrounding tropical forest itself is gorgeous. However, when you pay your entry fee to the garden they practically force onto each tourist a "free bottle of water" as a thank you for their payment. Whilst good intentioned, this leads to many thoughtless tourists to abandon the plastic bottle somewhere along their hike up towards the top of the waterfall. There was literally a bottle visible every ten steps, often with piles of them in places.
My advice is this: visit the waterfall absolutely, decline the water unless you really need it (but planning should've made you bring your own) and do your good deed for the day and pick up a bottle and put it in the trash near the entrance. If every visitor does just one bottle this place can return to its pristine natural state.
The second waterfall is over 4 times higher than its sister at around 80 metres. It is in fact a double fall, both roughly 10 metres wide that can be seen on the road up to the base of the fall. The road up is easy enough, although a little steep, and parking here is free. You will be assailed though by the sellers of , elephant treks, 4X4 jeep treks and trips by jeep up to the falls. But you do have the option of walking up. These same sellers will tell you it takes over half/hour, not true... There are two routes to walk up : 1) by the same concrete road (no cover and very hot the afternoon)that the jeeps take or 2) Through the small village near the elephants and up a dirt road cut through the jungle. This second option is much the better one and takes less than 15 mins. There is one small pool at the base for refreshing yourself and another one 3/400 metres up a track and then across some boulders in the middle of the falls. This is where the vast majority of people seem to stop. I'm told there is a good pool at the very top, but because of rain the track was very slippery and I never made it up there. Because of the heat I would recommend doing this fall in the morning.
Along with it's sister waterfall no. 2n, Na Muang I is situated on the south side of the island, up a cement road off the route 4169. Very easy to get to, no problem on a scooter or 2WD. The parking lot is on private land and costs 20 baht if you only walk up to the waterfall. If you're for the elephant trek it's free (commerce, huh). From the lot an easy walk through the woods about 300 metres and you're there. Not very spectacular, but nonehteless one of the highest on the island (18 metres).
This waterfall is situated to the south-east of the main port town of Nathon on the islands western side. It's quite some trek to reach from the entrance and not as good as Na Muang, although it's most secluded.
There are two Na Muang waterfalls where Na Muang Waterfall 2 is the one to head for and the furthest away from the main road. This waterfall has been visited by several Thai kings such as Rama V and his queen, Queen Saovapa Pongsi and later by King Rama VII. King Rama IX and his queen visited in 1962.
I am not too sure what is the hype about waterfalls in Koh Samui but I went to the Hin Lad Waterfall and I am not not too convinced. There were rubbish everywhere and the waters were dirty. I am not too sure about the rest but this one is best given a miss. I have seen better waterfalls.
When going on a Island Safari Tour, be sure to bring your trunks. The water is cool and you don't see s$%t... but it's a great refreshing experience. Also, make sure to walk up to the top of the waterfall. Great view.
The Waterfall is located a mile south of Nathon Town. It is approx. a 2 mile walk through the forest. The waterfall has several levels with a cool pool for a refreshing swim (so don't forget trunks and bikinis). In the dry season it may some seem like a bit of a trickle... Not as impressive as Na Muang waterfall.
There are a few waterfalls on Samui, they are better in the rainy seasons but by far the best one is Na Muang............heading from Lamai to Na Thon on the 4169 just past Wat Khunaram.
Here you will find tourist stalls, a car park (small charge) the waterfall and a lake that you can swim in.
The next best is Hin Lad just before Na Thon but it is very tricky to get to (by foot) and to be honest if you've been to Na Muang i wouldn't bother.
Located southwest Na Muang waterfall are a great place to visit.There are two waterfall Na Muang 1 with 18 meter high that someone can go with car and Na Muang 2 a 80 meter high waterfall that can be reached by 30 minute walk
Wanting to get off the beach after a few days baking, we travelled inland to see some sights. We followed the signs and a paved entrance road off the main highway that took us up to a small selection of huts and stalls selling souveniers and food. (FYI - best bar-b-que chicken - we went for seconds...) After just a few steps, we were at the base of the No. 1 waterfalls. Not so spectacular as I live close to Multnomah Falls in Oregon - however a nice way to spend the afternoon. We hiked up the 15 minutes to the No. 2 and spent a couple of minutes enjoying the thundering splashes from the waterfall all to ourselves before a group of children ran out from the jungle, jumping into water and enjoying relief from the heat.
Walked for more than 1/2 an hour to arrive at the top where there was supposed to be a waterfall... not enough water on the day I went...
Too dark up there to take decent photos to show how indecent the waterfall was.
