We were really looking forward to Carlos Rosario for snorkeling. It was pretty easy to get through the fence and a 15-20 minute walk down a well-trodden path was easy to follow and the beach was at the end (so no worries about missing it). Unfortunately, we had not bothered to get advice regarding time of day, tides, weather etc. When we got there early in the morning, the tides were so high that there was very little beach and the waves were crashing in, which was too intimidating. I tried to find the sign which some had indicated in their reviews marks the channels to go out so one doesn't damage the coral beds but I could not find the sign. We were the only people around and didn't think it was safe to try to snorkel given the conditions. We ended up swimming at Tamarindo Grande Beach (about few minutes away on the path). In retrospect, it would have been good to get some local advice and/or to go on a snorkeling tour so there would be someone with a boat to watch our backs (literally). We met a family as we walked back to Flamenco Beach that had booked a snorkeling tour for that morning that was cancelled due to the waves (or wind? It was sunny and quite comfortable outside). Of note, the fence was locked when we came in the morning but it was easy to slip through or over the chains. When we return 1.5 hrs later the gate was unlocked and wide open. The path is initially very flat and in the early morning shaded making for a pleasant walk as long as you have decent shoes. When you get about half-way there you can look down on the water on the other side and you realized that you have to go down (and back up when you are done). I was a little worried about slipping in parts but probably most reasonably able people would be able to make it. I was a little out of breath on the way back up but once the path evened out it was fine. People with knee problems or difficulties with ups/downs might find discomfort but otherwise the path would be doable for most.
The 15-20 minute walk from Flamenco is totally worth it, just be sure to carry your snacks and drinks. If you like snorkeling here you will see a wide variety of fish.
We hiked from Flamenco beach (thru the gate at the back of the parking - despite the warning sign, we stayed on the trail and didn't run into any of the unexploded mines the US government left behind). Its a long hike through wet & dry vegetation, but well worth it for the undisturbed beauty you'll find.
The unique snorkeling here is the amount of coral and various types of coral. Here is where I saw the sea turtles, and there is several types of fish as well. I found it surprising that there was hardly anybody at this beach.
Loved the hike and the sparsely occupied beach! Snorkeling was wonderful here. But for the love of god people, don't stand on the reef!!!
This beach was worth the effort to get there. You have to climb under a restricted gate (sliding on your tummy on the gravel) and then hike 20 min in the hot sun, but this secluded, gorgeous beach is so worth it! (Don't worry--the visitors info attendant at Flamenco beach told us to go under the fence, and we saw some other hikers go that way too). You park at Flamenco beach and then hike in to Carlos Rosario. We took our snorkel gear and spent several hours exploring a huge, healthy reef with a wide variety of fish and coral. A wonderful day, and only one other family and one fishing boat on the beach. Gorgeous!
Go to Flamenco Beach (in the parking lot), find the fence with the locked gate, the sign reads "danger, no trespassing, explosives", that's where you enter. Take the trail and hike for about 25 minutes. You will then come to a beautiful beach. Great snorkeling, crystal clear water.
Best snorkeling ever!!!! Easy and nice even for kids. Wonderful coral reef and plenty of tropical fish around!A must!
Had a great time seeing Coral Reefs and lots of colorful fishes. Would go any time again, it's great.
There's a locked half open fence with a big sign that reads: "Danger". That's where the path starts. You have to climb thru the gate and walk about a mile up and down hill each way. Bring water, if you can. There're no vendors, no facilities, just beautiful beach. The coral was really pretty, but the beach was kinda rocky and we were fighting the current for most of our snorkeling time. The water is clear and the beach is just gorgeous! Grand Tamarindo beach is also on this path.
