In December 2013 we traveled to Costa Rica for a 10-day vacation. The trip was indeed amazing and far exceeded our expectations. We visited the Pacific coast in the Uvita region which includes the amazing Bahia Ballena Nat'l. Park.
We actually stayed one night in San Jose at the start of the trip and again at the end of the trip; we spent 9 nights/10 days in Costa Rica. We HIGHLY recommend the Pacific Rim of Costa Rica around the Whale Tail.
