This is for those of you who are driving yourselves to the park. I used a GPS and it somehow stopped me well short of the park. Just follow the signs after getting to Quepos. Once you pass all the hotels that are going up and down the mountain you will be on a beach front street. This is where it gets interesting and get ready to go into sensory overload. There are literally bands of people that will stop you using every form possible trying to con you into either parking or to take a tour. They will actual get in front of your car and demand that you stop. They all have some kind of official looking shirt on and one guy even blew a police type whistle to get me to stop. They are all tour guides and not Park officials or Police. They will tell you all sorts of stories like "the park is full and you can't get in without a guide" to "there is no parking so you must park here". Its all a sales pitch. The trick is to just insist that you are going to the park entrance which is quite a ways from the start of the onslaught. I made the left to the park and since cars are not allowed in the park, yes, you have to pay to park. But I found a great space right in front of the gate and right next to the official ticket stand. $6 to park and $10 per person entrance fee. But It didn't end here. As I got out of the car the next onslaught of tour guides descended upon me. I almost had to fight them off with a stick. They were all very polite but damn it was rough. One guy even said that it is a 90 min walk to the beach. B.S. I bought my tickets and entered the park. Whew! Peace at last. The bottom line is 1. Get there early. They only allow 600 people in at a time. 2. You don't need a guide. The monkeys greeted me almost at the entrance. 3. It's a 15 min walk to the first beach. We pretty much toured the entire park in about three hours stopping to eat lunch and to take a dip in the water. 4. Make absolutely sure you bring a full lunch with extra water. There are no vendors of any type in the park. If you wait and try to buy something just outside the gate they will soak you for it. 5. Beware of Yogi Bear type raccoons. They will go out of there way to steal your "picinic basket". I was making sandwiches and almost got gang tackled by a group of them. If you are out on the beach, the monkeys will do the same. Other than that, it's awesome as already mentioned in other reviews.
