The Puna Rainforest Retreat is off the beaten trail and provides a fabulous rainforest steam vent hike, clean private hot spring tubs, and a sweet cottage with kitchen and bathroom basics. Robes were provided and the sunrise view through the cottage windows was fabulous.
It’s best if you try to get here before dark (and remember, the windward side has an early-ish sunset) as it gets very dark and somewhat difficult to navigate your way. Also, the internet doesn’t work so well in the jungle, so make sure you know where you are going ahead of time.
