Though they are little, there is enough room for four to six people to bask and enjoy. Please note that the area is delicate and you need to tread carefully not to ruin the flora.
The springs are right beside the road, noticeable as the smaller one is surrounded by a ring of stones. There are no changing facilities, but you may leave your clothing on the grass nearby. One thing to beware of is that the grass on the pools' edge can become quite slippery, especially in the rain, and there are algae at the bottom of the springs, so be mindful of your footing when getting in and out.
