We spent 6 nights (June 28-July 4 2012) at Blue Osa using a Groupon promotion. It was a trip of a lifetime. First off, my fiance proposed to me the 1st morning we woke up there to a beautiful sunrise on the beach. I have wanted to visit Costa Rica for years and this exceeded my expectations. At Blue Osa we enjoyed several of the activities and tours available. The staff was wonderful and friendly. There was a yoga retreat for instructors the week we were there and they allowed me and my fiance to join in their sessions. The massages were great, we were with young woman whose name has slipped my mind. We went on the Corcovado day trip (saw amazing wildlife), on the Rainforest Bike and Hike (saw more amazing wildlife and a small waterfall that flows into a nice sized pool), and we also did the Waterfall Rapelling. The Waterfall rapelling was awesome!!! The weather was hot but the rain in the late afternoon or evenings cooled it off for bedtime.
There isn't even a strong enough word for how great the food is at Blue Osa! The food is fresh, delicious and unique. Maria and her staff were great. Since we all eat together, we ate with Yoga group and some had restrictions in their diets so we all ate the restricted diets but it didn't stop them from delivering the same quality meals.
It was a wonderful trip where we were able to relax in a peaceful atmosphere in the middle of a jungle with a beach and without all the chaos and technology that distracts us in our normal routines.
The only thing that I would say is not to go in with super high expectations on the rooms. The rooms were nice enough, but remember you are in the middle of the jungle and it is hot and there is no air conditioning. It is more of a camping type feel but that is part of the unique experience.

Blue Osa is beautiful, the food tasted wonderful, everyone who works there is so helpful and knowledgable, and the yoga and messages were very relaxing. I showed up a stressed out, anxious creature and left as a new woman, relaxed and finally at peace with myself.

This was a great place to be part of nature, yet still have wonderful facilities and amenities within reach. A very safe location, with all sorts of fun activities and tours to do, or just relax and let your mind finally wander into pure happiness.

I will definitely be returning!

We spent 4 nights at Blue Osa using a Groupon promotion. It was fun, friendly and relaxing...there are activities/tours available or you can just veg....great massage by Jesus, excellent food at every meal, informative and helpful guides. Flights across the country were fine. People in general in Costa Rica were great. Points of note: because of the heat/humidity, activities at Blue Osa can start early (yes, like 5:30 a.m.) and once the sun goes down (which happens fast at the equator), people generally go to bed. No blow dryers and short showers, which was fine since you're generally drenched anyway and so is everyone else. Lovely lap pool. Everyone gets to know everyone else since you're eating 3 meals a day together. If you need something going on all the time, or need shopping or nightlife on a vacation, this might not be a good fit. If you need to recharge and get close to nature in a fairly luxurious setting, this is a lovely spot.

This was the perfect end of a very enjoyable exploration of Costa Rica. Blue Ossa is remote, beautiful, and very rejuvenating. The staff is wonderful and engaging without being obsequious. It felt more like a loose “family” than a “resort”. The food was delicious, and the deep tissue massage was the best I have ever had! In addition to the tranquility, there are tours (hikes, walks, kayaking, etc.) into the jungle and on the bay that add the right touch of interest and excitement. I particularly recommend the “Bike and Hike” to the waterfalls, where you can find many animals, including poisonous frogs, four types of monkeys, countless types of birds, and many other animals large and small. The cool swim at the base of a delightful waterfall was very fun and refreshing on a hot day and one of the many highlights of the day! The in-house tour guide was very friendly and knowledgeable. Another real pleasure is talking with Marie about cooking, or discussing her history and experiences on the Ossa peninsula. One last thing not to be missed: There is a nearby local outdoor restaurant/bar that on Friday nights throws an energetic “party” with music, good drinks, and food. It is THE event for the local singles and families, and for those tourists that have the good fortune to hear about it! -- Pura Vida
