We were amazed by the variety of different beaches Costa Rica has to offer - and we only visited a few on the Pacific Coast. We found that even beaches that were right next to each other could vary dramatically in terms of sand color and composition, presence of rocks, water clarity, wave conditions and vegetation. As a result, it's worthwhile to visit more than one beach because you can count on a dramatically different experience.

We found that it was a good idea to stay in Tamarindo and make it our "home base" while doing the beach thing due to the town's wide (and ever growing) selection of lodging, restaurants, shopping and services. If you get tired of Tamarindo, there are several nearby beaches that are worth exploring (and many that are not). Here is a quick rundown of the beaches we visited, starting of course with Tamarindo and Langosta and then moving North (we didn't go South because those beaches were further away). Keep in mind there are generally no public restrooms or showers at any of the beaches - it's usually not an issue though. The only services would be restaurants or stores nearby, which I will mention if they exist.
Beach Reviews
Tamarindo: On the fence. Fine light brown sand beach. Mainly a place where people learn how to surf on the gentle waves. Conveniently located next to the main street in town - making food and services easily accessible. A few parts of the beach have large rock formations in the water, but these areas are obvious and easily avoided (just follow the crowds). If you like surfing and people watching, this is a good place to go and the most crowded beach you will find in the area. But the beach itself really isn't that great nor is the water clarity very good.
Langosta: Not worth it. This beach is adjacent to Tamarindo on the South side but
separated from it by a rocky outcropping. The beach itself is not that nice. The beach is narrow, has quite a slope to it and the sand is coarse and there are many rock formations all over the place. Combine all this with rough waters and this is not a beach for playing in the water.
Perhaps the only attraction is on the South end of the beach, where it ends at an estuary. People occasionally kayak up the river and at low tide there were locals fishing shellfish out of the tidepools in the rocks. The estuary can also make for some big waves, but the resulting longshore current is very strong and when I was there the waves were closing out - not a good place to surf or bodyboard.
Playa Conchal: Worth visiting. This picturesque beach is made up of eroding white
seashells. It's long enough that you could find some seclusion if you wanted. The water is usually pretty clear and calm, and a rock outcropping at the North end of the beach makes for good snorkeling.
Getting here can be confusing though. From Tamarindo, drive past the mega-resort Paradisus Playa Conchal (they won't let you access the beach through their resort anyway - unless you want to pay their ~$80 resort fee!). Stay to the left and look for a small dirt road that runs South right along the beach. Lining this road are several rinky dink looking outdoor restaurants - it probably won't look like you're going the right way, don't worry. Keep going and you can actually drive onto the beach, across a nearly dry estuary, over a small rocky hill (you'll likely need 4x4 to make it due to ground clearance issues), and voila! There is a rather impromptu parking area under the trees right in front of the North end of beautiful Playa Conchal!
The beach is very secluded and there are no businesses except for those restuarants you passed a ways back.
There are also local vendors present renting snorkeling gear. The snorkeling isn't all that great, you'll see some fish but that's probably about it. It's certainly not as colorful as snorkeling in the Caribbean. Still, I love white sand, turqoise water and snorkeling, so this beach made for a worthwhile stop.
Playa Brasilito: On the fence. If you go North
from Conchal and continue on the road running along the beach, you will pass through a small neighborhood of homes and find deserted Playa Brasilito on the other side. You can drive right onto the beach (and all over it if you really like). The sand is very fine and almost black (so it's very hot) and it continues on for quite a ways. Not a store or vendor in sight and the water is very calm like Conchal. I didn't go in the water though because it didn't look as clear or inviting as Conchal and there were no rock formations in sight for snorkeling. If you go to Conchal you might want to stop by and have a look, but it's not worth a separate visit just to go see this beach.
Playa Flamingo: Worth visiting. This was my favorite beach.
This pristine beach is very long and wide. It has cotton candy soft white sand, turqoise water and playful waves. It was also practically deserted.
To get here, follow the signs to Playa Flamingo and then you must drive South of the town of Flamingo - that's the one prominently perched atop the rocky outcropping (can't miss it - look for tall condos and hotels). Don't be fooled into thinking that the black sand beach with calm waters to the North of town (where all the boats are harbored) is Playa Flamingo - it's nothing like it. There is a dirt road running alongside the beach where you can park (I wonder if
development is planned for this beautiful beach).
The waves made for great bodyboarding or bodysurfing. The sand was also so soft that it didn't matter if you wiped out and hit bottom. No facilities or stores nearby except for the town of Flamingo on the hill.
Playa Ocotal: Avoid. This beach feels dirty. You have to drive a couple miles through a residential area to reach this teeny weeny black sand beach. Once you arrive the road basically dead ends and there is some impromptu parking available. You are greeted by a big trash can and probably a nice rotting smell too. Watch out for mosquitoes too near the parking area. Walk across dirt (it will probably be a little muddy) and the ground transitions into black sand - whose muddy consistency and dark color doesn't help the dirty feeling you get.
The water is calm. There is a large rock formation at the North end of the beach which makes for wonderful snorkeling. I actually saw a big eagle ray here. However, I would rather snorkel at Conchal than this dirty-feeling beach.
Playas Del Coco: Avoid. This is actually a big town, perhaps rivalling Tamarindo in size. However, it feels very old and dilapidated (think Tamarindo in 30 years). I got the feeling that the place was wasting away. Street vendors easily outnumbered the tourists we saw - although we did go in July which is low season. I understand the main tourist draw here is fishing and diving trips. We took one look at the beach and turned around. Not even worth a visit.
Playa Hermosa: Avoid. This is a very long and wide beach with calm water and boats anchored offshore. The sand is dark and fine. We walked up and down the beach a bit and noticed that locals outnumbered the tourists. This beach was the most crowded next to Tamarindo. The water did not look inviting so we didn't go in. We got a similar "old and dilapidated feeling" as we had about the town of Del Coco. We took a peek at one of the hotels right on the beach, supposedly one of the nicer places to stay in Hermosa. We were greeted by an army of dragonflies (an impressive sight) patrolling the front of the hotel - which is both a good and a bad sign (bad since it implies the presence of lots of mosquitoes). The hotel itself was "old and dilapidated" looking and made us feel good that we had chosen to stay in Tamarindo.
