Preferably visit on the whale watching season, and reserve a tour days before so you not lose the chance of this lovely experience, I recommend Bahía Ballena Kayaks & Tours. Beach is beautiful and relaxing, check the tide hours son you can walk to Whale's tale in low tide, and also have like 200 meters of beach to enjoy
Uvita is a great spot for families, not as crowded as Dominical, with plenty of good places to eat. However, some restaurants can be pricey and not worth it. The sea had strong currents, making it dangerous, but there was still plenty of space on the beach
My stay in Uvita was wonderful because it was October and very quiet. I was lucky to have no rain most days and explored all around the area. I loved playa Hermosa and Bahia Ballena. Both places you can walk see endless beach that's almost all to yourself during the fall.
I went to Uvita in Sep because I wanted to see the whale. While some other boats did, we didn't get that close to the whale, so the experience was not ideal for me. However, it is an excellent place for surfing, and the tide is perfect.
Uvita was a great surprise. It has a very good vibe and the best waterfalls for us (we love jumping into pools) - El-Pavon and Uvita waterfalls are pearls (and they're almost free which is rare in CR)
Whale watching was amazing, however it feels a little intrusive. We were assured that the boats are only allowed to go out certain times in the day and not at all at certain times of the year. Considering how well Costa Ricans look after nature, I did believe this to be truth.
