Town on the Osa Peninsula



Uvita is everything you imagine when you think of Costa Rica.

The beaches are beautiful long stretches. The forests are dense and jungle-ish. The waterfalls are plentiful. The people are the sweetest.



Dominical consists of a small (but lively) downtown area, beaches, and dense jungle mountains.

Even though it is a small town there are still plenty of excellent restaurants and many to do.



I feel like Ojochal is one of those places that needs to grow on you. It is an absolutely beautiful area, but it doesn’t have the unique vibe that some Costa Rican towns have.

I think a big part of this is the fact that there is no distinct downtown area.


Puerto Jimenez

A good place to stay if you are visiting Corcovado National Park. This town has a decent amount of infrastructure and is home to some beautiful Golfo Dulce beaches.

Drake Bay

A gateway to Corcovado National Park. This small village is the perfect place to disconnect from the world.

This town is home to the world’s largest left hook. It is a popular destination for surfing enthusiasts,. It is a bit of a challenge to get here.

The Osa Peninsula Weather

The dry season and main tourism season in Costa Rica is from late December until late April. During this time of year you can expect crowds and higher prices in this area. 

This especially applies to the more popular beach town like Uvita.

From May until August prices go down a bit, the crowds go home, and the weather turns somewhat rainy.

You can expect afternoon rainstorms to last about one to two hours. 

If you plan on visiting the southernmost points of the country (Drake Bay, Golfito, Puerto Jimenez) you need to be prepared for the fact that there are many roads that require river crossings.

Sometimes it is not possible to cross these during the rainy season. 

From August until December prices usually get even lower and many places close due to the lack of tourism.

At this time of year, you are more likely to experience rainy days.

The temperature year-round is usually in the upper 80°F (around 30°C) during the day and dips to about  65° F (19°C) at night.

Year-round the sun rises between 5:15 and 5:45am and sets between 5:30 and 6:00pm.

The Osa Peninsula Transportation

There are multiple transportation options to get to and around in the South Pacific area of Costa Rica.

We usually suggest renting a car because it will give you the most flexibility in getting around between locations and it will allow you to explore more on your own.

You can book your rental car with a 10% discount plus other great perks here. 

However, if you are planning on staying at a resort or plan to mostly take day tours with transportation included, it is most likely not necessary to rent a car. 

In this situation, you could opt for a private shuttle.

You can book your private shuttle with our favorite shuttle company here

If you are on a tight budget, the public bus is always an option. Here is the best place for the bus schedule.

Is the Osa Peninsula Worth Visiting?

We think the Costa Rica Osa Peninsula is worth a visit. The fact that this area is known as one of the most biodiverse places on earth is a good reason on its own.

This area also boasts an incredible array of plant and animal species, including jaguars, monkeys, sloths, and scarlet macaws, and is not typically as popular destination with tourists.

I think that makes it the ideal place to experience the true Costa Rica.
