Mauna Lani spa, one of the most luxury spas on the island, takes DIY to a decadent level at the Lava Sauna. While sitting on lava rock, you get to smooth black volcanic clay all over your body. It’s cool, which is good because it is hot outside in this circular enclosed area that you’ve got all to yourself. After the mud dries, you’ll be delirious from the hour you spent in clay-covered repose. Your skin will be as smooth as the Ili Ili stones you were resting on, your lowered stress levels will thank you, and after a rinse off in the outdoor shower you’ll be presentable again.
Bonus: at just $85 for 50 minutes, the cost is not going to shock you back into pre-spa tension levels.
