"Lovely! A quiet jewel just 10 minutes outside the Santa Teresa's main district. Great adults-only resort, terrific restaurant, lovely beach, great rooms, wonderful massage. The resort, rooms, beach club, beach, staff and experience are all top notch.
Can't overstate how excellent the restaurant is, whether breakfast lunch or dinner. The pool may be the only slight knock - it's lovely and unique, but small and accessible to only a few villas. But we didn't actually care. The beach club, beach, Santa Teresa, and neighboring Montezuma were all charming enough to make this a great experience.
You'll want / need a car if you stay here. Relying on open ATV would be bad - you'd be covered in dust from the 10-15 minutes of dirt road between Blue Mist and Santa Teresa. We rented a 4wd Bronco from Liberia, which made the 4 hour drive in regular mode and last 15 minutes of gravel rough road in 4wd no problem.
Nearby: Nami (best sushi in town / 5 min from Blue Mist), Katana (best restaurant in town), Pronto (best italian in town), Umi (best night beachfront bar experience), Tipsy (best wine shop)
Tour: From Blue Mist we booked a Montezuma Falls guided hiking trek with Grasshopper Tours. Make sure to get Ernesto - a truly lovely local who literally grew up hiking and playing in the falls before it was a tourist destination. A great guy!
We booked a Zumi tour to Tortuga Island from Montezuma village. Tour good, snorkeling fine, Island was boring, but we loved the town of Montezuma!"
