I put the Pong Arng Hot Springs in things to see in Chiang Dao but it's more to do. Diving in naturally warm water ponds is very relaxing. Situated 3-4 kilometers before Sri Sungwan Waterfall, these hot springs are also part of the Pha Daeng National Park. The entrance ticket gives you access to both places. It is up to you to see in what order you wish to make them. Hot water first or cold water first. Personally, I preferred to end up with hot springs.
