We stayed there 9 days at the end of Feb. 2011 - we tried all the 3 types of bungalows (800-2000TB) and all where good. It is good place form the kids, food is pretty OK but the best is the silence and relaxed environment, no bars or karaoke no music in the restaurant and no sound from the mountain roads.
No Pool but a great pool next door (which can be used)
Good free Wi-Fi
easy access to the larger beaches and waterfalls which should not be missed
overall very pleasant, low key and cheap :-)

A good stop in the calm part of Koh Pha-Ngan, bungalows on the beach are wonderful

We stayed at the Wattana resort for 6 nights at the beginning of our family trip to Thailand this summer. We are a family of 6 so rented a family bungalow and a standard bungalow between us. The bungalows are basic but clean and cosy. The beds are pretty hard but they are pretty much the same everywhere in Thailand. We chose the location because we wanted to be far away from the crowds coming for the full moon party. It was a perfect location for a family, but if you are looking to party it is probably the wrong place for you. Each bungalow has a hammock and you have clean towels when you arrive, but just be aware they aren't changed after that.

As other reviewers have said, it is a family run resort, so we feel like we really got to know the owners and their adorable little girl who visits with everyone at meals. Out of all of the places we stayed on our trip, this was number one for my kids, probably because it was so friendly and personal. We were picked up from the ferry by the owners and brought to the resort. The food is fantastic here and the price is reasonable. We went to a few other places but ended up eating here for most meals as they were the best. The beach is right out the door. We were a little disappointed that the water was very shallow during the day and not really swimmable until the evening, but we discovered that this time of year most of the beaches on the North and West sides of the Island are like this. We walked into the little village along the beach often. There are some great little seafood restaurants right on the water in the village that are worth trying.

We rented a longtail boat for a day and toured the East side of the island to various beaches. The swimming is much better this time of year on this side of the Island, but it is true that you can get stuck there. The weather turned on us when we were at Bottle Beach and we were stranded for a few hours until the storm let up. Koh Mah is a 30 minute walk or a 5 minute scooter ride and had some good snorkeling. The beach there was a little dirty and there is construction going on so I wouldn't want to stay there. We hired a driver to take us to the beaches on the West side of the Island for the day which was reasonable.

My husband and I were in Koh Samui for our honeymoon 20 years ago and brought our 4 kids back to Thailand for our anniversary this summer. Koh Phangan is definately much quieter and nicer than Samui and we would highly recommend the Wattana if you go.

We stayed in the modern bungalow for 4 nights and the resort is very relaxing and quiet. The resort is at the end of the bay and is about a 10 - 15 minute walk into town. There is also a restaurant which is open all day. The only downside was that our room wasn't cleaned during our stay and we had to ask for clean towels and bath mat and change the toilet bin. However nothing else could be faulted so was good value for money.
