The central valley generally has a mild and pleasant climate, with temperatures ranging from approximately 15–30 degrees Celsius (mid-60s to low 90s Fahrenheit) throughout the year. However, the weather can vary depending on the time of year and the specific location. The region is mountainous with colder temperature on higher altitudes like for example the Poás volcano. The dry season in the area runs from December through April, with January and February being the driest months. The rainy season runs from May through November, with September and October being the wettest months. 

San José is the capital and largest city of Costa Rica, located in the central part of Costa Rica, the Central Valley region. It is situated at an elevation of approximately 1,160 meters (3,810 feet) above sea level, making it one of the highest capital cities in the world. The surrounding metropolitan area, is home to a significant portion of the country's population. The city has a rich history and has played a central role in the nation's political, economic, and cultural development. San José was founded in 1738 and officially became the capital of Costa Rica in 1823, following the country's independence from Spain. Despite the history of the city, the general impression when walking through the city center is not that of a colonial city, although there are some buildings of cultural significance such as the Teatro Nacional, The Metropolitan Cathedral of San José, and the Museo Nacional which is located in historic military barracks. 

This National Museum is worth a visit as it offers a fascinating glimpse into Costa Rica's history, culture, and natural heritage. It features pre-Columbian artifacts and colonial art. The Teatro Nacional is an architectural masterpiece and still functions as the national theater, hosting various shows performances. Below the plaza next to the Teatro Nacional is the Museo de Oro (Museum of Gold). This museum is a showcase of pre-Columbian artifacts and as the name suggests a lot of them are golden artifacts. Despite all of this, San Jose is mainly the business and governmental hub of Costa Rica. You will be entertained if you have to spend a day or two in the capital, there are plenty of hotels, good restaurants and more highlights other than I have mentioned. You can use it as a base to visit some nearby highlights, but I would advise you to not stay too long in San Jose, as Costa Rica has so much more to offer. But before you go, don’t forget to visit the Mercado Central (Central Market) which is a large marketplace for fresh produce, traditional dishes, handicrafts, and souvenirs.

Braulio Carrillo National Park is one of the larger national parks of the country, located north-east of San José. The vast part of the National Park is located in the Heredia province and smaller parts in the San José, Limón and Cartago province. The best known part of the park is the located in the San José province. This is because in this area, Ruta 32 the highway from San José to Guapiles and Puerto Limón on the Caribbean coast, runs through the park. This part of the highway is already insanely beautiful and a true attraction, with nice views over the pristine forests of the park. 

If you have time to spare when travelling between San José and the Caribbean, you can visit Braulio Carrillo National Park at the Quebrada Gonzalez sector along Ruta 32.  Due to the convenient location of the ranger station close to Ruta 32 and two relatively short hiking trails, it is easy to fit into your itinerary. From the ranger station, you can access the Las Palmas trail is 1.6 kilometers (1 mile) long and will take approximately one hour. From the ranger station on the other side of Ruta 32 you can access El Ceibo trail. This trail is only 1 kilometer (0.6 miles) long and will take approximately 45 minutes. The trail will take you to the Rio Sucio lookout point. Check the official website SINAC ACCVC BCNP for more information.

Alajuela is the capital city of the equally named province, located in the hearth of Costa Rica north of the nation's capital San José. It is one of the first places most people will visit when coming to Costa Rica. This is because the main international airport of Costa Rica, although abbreviated to SJO for San José, is located in Alajuela. This airport is officially known as Aeropuerto International Juan Santamaría, named after Juan Santamaría Rodriguez who became a national hero who died after his actions were decisive for winning the second battle of Rivas during the war between Costa Rica and the American mercenary forces of William Walker in the 19th century. If you're interested and have some time to kill, you might want to visit the Museo Histórico Cultural Juan Santamaría located in the city center. Although the town has some historical significance and some colonial buildings, of which the aforementioned museum and the beautiful white Cathedral of Alajuela are worth a visit, most highlights of the region are found outside the city. Surrounded by coffee plantations, the town enjoys a temperate climate and serves as a gateway to exploring the North Central Valley's natural wonders.

Poás Volcano National Park is located north of San José in the province of Alajuela. Poás is closely located to San José and the town of Alajuela. This makes it an ideal trip when you are staying near the capital or near the airport. The main attraction of the park is the Poás Volcano with a height of approximately 2700 meters (8850 feet) above sea level and has a very impressive and large crater. The Poás volcano is an active volcano. Activity is visible in the hot and acidic lagoon of the main crater, which is in fact a large geyser. Small geyser eruptions might occur and witnessed if you are lucky. The park also has a hiking trail to Laguna Botos, an old crater lake.  Access to the park is limited and tickets can only be bought online. From the parking lot it is a short walk to the main crater and the Laguna Botos hiking trail is not that difficult, but very nice as it shows the distinctive low vegetation of the volcano area. Check the official website SINAC ACCVC Poás NP for more information.

Bajos del Toro is an off the beaten path area and is home to several breathtaking waterfalls. I will describe two of them, but if you research the area, you will learn that there are more that are definitely worth to consider visiting. A day trip from San José or Alajuela is possible, or you can choose to visit this area on your way to La Fortuna in The Northern Zone. If you want to take your time to explore this area, it might very well be your first stop after arrival at Juan Santamaria International Airport. Note that the main road through Bajos del Toro is paved and does not require a 4WD, but it might be a more challenging and foggy road for which you want to take your time.

Catarata del Toro is a privately-owned ecological waterfall project. The trails in this park are well maintained and will take you to an impressive high waterfall tumbling down into an old volcanic crater. You can get to the base of the waterfall by descending a stairway trail. The park also contains lookout points with views towards Castro Blanco National Park. Check out the website of Catarata del Toro for more information.

The Blue Falls, are a combination of several bright blue waterfalls (La Tepezquintle, Las Gemelas, La Celestial, La Turquesa, La Pintada) surrounded by tropical forest. The project has a secured parking area and there are restrooms available. You are able to swim at various natural pools, but be aware that you will have to undertake some light to moderate wet and slippery hiking to get around the project and flip-flops are not allowed for this. The first two blue waterfalls are a1 kilometer (0.6 miles) walk from the parking. You can make a 2 kilometer (1.2 miles) and 6 kilometer (3.8 miles) roundtrip, depending on which waterfalls you choose to visit. Check out the website of The Blue Falls for more information and hiking options.
