The Emerald Pool, Sa Morakot, is a natural pool in the Khlong Thom forest reserve, about an hour inland from Ao Nang. Its name comes from the water, which is a bright blue-green that looks lit from within, fed by a cool stream and surrounded by trees. Nearby is Namtok Ron, a hot spring waterfall, where warm mineral water cascades through terraced pools you can sit in. The pair make a restful contrast to the island days, with shade, birdsong and a cooler climate. The Viator half-day jungle tour we link, rated 4.1 from 36 reviews, runs about six hours with hotel pickup from Krabi Town and Ao Nang, spends around two hours at the Emerald Pool and one at the hot spring, and uses a group of up to fifteen. The national park fee is not included and is paid at the entrance.
What to expect: the Emerald Pool is a swimming spot with cool water and a gentle walk from the entrance. Paths lead through forest to the hot spring, where you can sit in warm pools, and a viewpoint offers a short trek if you want exercise. Bring a swimsuit, towel, insect repellent and shoes that can get wet. Lockers and a few stalls near the entrance sell drinks and snacks.
Timing: both places are busiest from late morning, when tour groups arrive, so an early start gives the best experience. The hot spring is pleasant in the cooler months and in the evening, when the heat softens. Because the pools are natural, water levels change after rain, and in heavy wet weather they can be closed or murky, so check conditions with your operator.
Combining it: the tour is a good pairing with the Tiger Cave Temple, either as a full-day combination or as two separate trips. If you prefer to travel independently, hire a taxi for the day, and bring cash for fees. Be aware that fees for foreign visitors are higher than for Thai residents, and that the fee on the tour page is not included in the ticket. This is the most relaxing day in a Krabi itinerary, a good choice on a day when the sea is rough or after a run of boat tours.
