Swimming pools

I know there is one at the big hotel opposite Tescos but that gets expensive. Are there any other pools in the town?

There are two others I know that are open to the public.

The municipal pool is at the stadium, don't know the price or when it is open, though should not be expensive.

Then there is the one at Benjamarachutit School, open, I believe from around 4:30 pm to 8pm weekdays and Saturdays all day. Cost 20 Baht for the public.

Both are Olympic size pools with stadiums if you wish to bring down an audience.

I don't know about swimming pools, but there some really nice waterfalls just out of town ... clean mountain water in beautiful scenic settings - way better than a swimming pool. Just head out to the mountains and you'll find them.
