I had no previous experience with Costa Rica, so I was a virgin to the hospitable culture as well as to The Blue Osa Yoga Retreat. I was with my partner attending a yoga retreat and as you might imagine from the website, it's a perfect place for such an event. The group was great, the room was beautiful and an excellent beach - practically private. Truly one of my best vacations ever. I've always been a fan of the Big Island, but traveling from the East coast - it's just too long of a journey for a week. Costa Rica was a short 4 hour flight to San Jose from Charlotte, NC and then a small plane connection to the Osa Peninsula. Better to arrive a day before your retreat for an overnight in San Jose. Not much to see or do in San Jose, but it makes for an easier trip. I preferred Nature Air for the local flight even though it's at a different airport. Less restrictions on luggage weight and the taxi trip is about 25 minutes from almost anywhere in San Jose.
The food and staff are equally as fantastic. It's was Valentines Day during our visit and the staff made our room especially beautiful as a surprise for my partner. Very sweet!
I feel like I will visit The Blue Osa many times in the future. I personally think that visiting a place as remote as The Blue Osa, it's best done as a group retreat. However, I spend a lot of time alone (too much) and I loved the group energy. That's just a personal preference.
