I'm blessed to have a wife who doubles as a Yoga studio owner. She put together an all inclusive trip to a resort where Yoga is the emphasis. There's a few resorts like this around the World and we chose Blue Spirit in Nosara. We brought 25 people here so the staff and locals love us. There's only about 40 people staying here all together. THe other group is a yoga teacher training group out of LA.
We do Yoga first thing in morning and another class in the evening before dinner. In between is lounge around time. I surf now. Got a 10 minute lesson from a local Tica named Nelson. Spent the last couple days on the surf board doing my thing.
The resort is on a massive beach side property, but the grounds are almost like a rain forest. Howler monkeys are walking around above you at all times. Huge ass spiders and tons of little geckos are very common.
Highly recommend Nosara for a week getaway. MHK-Dallas-Liberia Costa Rica airport= 5 hour total.
