Alajuela holds the main airport, and the province runs from that city north to La Fortuna and Arenal. Poás is a morning drive up from the valley. Atenas sits in the hills on the way west. It is the piece of the map people fly into and then leave. Poás and La Fortuna sit on the Central Valley pages, Bijagua on the North Pacific pages, and Los Chiles and Upala are farther north.
Where Alajuela is
The capital of the province is the city of Alajuela. It starts at the airport, runs through Atenas, and continues north to La Fortuna and Arenal. Poás is in this province, not in San José. The north reaches the border with Nicaragua, at Los Chiles and Upala. That landscape is not the city.
On this site Poás, La Fortuna, Arenal, and Atenas are filed in the Central Valley. Bijagua is filed in the North Pacific. The province is larger than either label. The city and the volcano share a name and not a climate. One is a night beside the terminal. The other is hot lowland under a cone, a few hours up the road.
Alajuela has restaurants and rooms a few minutes from the Juan Santamaría airport.
La Fortuna is the town at the base of Arenal, for the volcano and the hot springs.
Arenal Volcano is the cone you look at. The hot springs are why people stay.
Poás Volcano is an active crater in the park above Alajuela, worth the drive on a clear morning.
Atenas is a valley town with a mild climate, coffee farms, and green hills around it.
Bijagua is a small town west of the lake, for the blue water at Río Celeste.
Getting around
Juan Santamaría (SJO) is in this province. It is the airport people mean when they say they are flying into San José. The city of Alajuela is the night before an early flight, not a second capital. The square is a short taxi from the terminal.
Route 1 continues through the province toward the northwest and Liberia. The other international airport is Daniel Oduber (LIR), in Guanacaste. A Liberia ticket does not help a La Fortuna week, and an SJO ticket does not help a Tamarindo week. La Fortuna and Arenal are about three hours north of the valley. Poás is a morning from the city, not from La Fortuna. Do not plan both craters on the day you land.
Stay in the city if the flight is early. Atenas is the quieter hill if you have a full day and do not need to be at the curb before dawn. Do not sleep on the coast the night before SJO.
Parks and protected areas
These national parks are in Alajuela: Poás Volcano, Arenal Volcano, Juan Castro Blanco, and Tenorio Volcano (part).
Alajuela province starts at the airport and the city of Alajuela, runs through Atenas, and continues north to La Fortuna and Arenal. Poás is in this province, not in San José. The north of it reaches the border with Nicaragua, which is a different landscape from the city.
The city and the volcano are the two trips people mix up. One is a night beside the terminal. The other is a hot lowland under a cone, a few hours up the road. They share a name and not a climate.
Juan Santamaría (SJO) is the airport in Alajuela province. It is the airport people mean when they say they are flying into San José. The other international airport is Daniel Oduber in Liberia, and that one is for Guanacaste. A Liberia ticket does not help a La Fortuna week, and an SJO ticket does not help a Tamarindo week.
The city of Alajuela is the night before an early flight, not a second capital. The square is a short taxi from the terminal. You skip the crawl through San José if the plane is at dawn.
Yes. La Fortuna is in Alajuela province. The town, the waterfall, and the cone you look at from that side are Alajuela. The north shore of the lake, Nuevo Arenal, is Guanacaste. The line is the water, not the drive around it. Bijagua and Río Celeste are Alajuela too, farther west, and they are their own morning.
Poás is the other famous piece, and it is a morning from the city, not from La Fortuna. Do not plan both craters on the day you land.
Stay in the city of Alajuela if the flight is early. Atenas is the quieter hill town if you have a full day and do not need to be at the curb before dawn. Neither is a beach. Do not sleep on the coast the night before SJO.
A house search in this province usually means the hills around Atenas or the edge of the city, not La Fortuna. La Fortuna is a visit. The valley is where people stay.
Alajuela province has three climates. The city is a little warmer than San José and still nothing like the coast. Poás and the upper slope are cold and wet, and cloud often takes the crater by late morning. That is why the visit is at opening. La Fortuna is low and hot, with the same afternoon rain as the rest of the north from about May to November.
Pack for two climates if the plan is the airport and a volcano on one ticket. A beach wardrobe is the wrong bag for Poás, and a valley jacket is the wrong bag for the Arenal pool.
The local attractions in Alajuela province are Poás, the La Fortuna waterfall, Arenal, Doka Estate, and Atenas. Two of these are a morning from the city. Two of them are a different day, up north. Atenas is the one you can do on the way.
- Poás Volcano: A steaming acid lake fills the main crater. You look from the rail and stop there. Be there at opening. Late morning is often white.
- La Fortuna waterfall: A long stair drops to a cold pool under the falls, a short ride from La Fortuna. Swim only if the current allows. The hard part is the climb back out.
- Arenal Volcano: You look at the cone from the base. You do not climb it. Morning is clearer, and by afternoon the peak is often wrapped.
- Doka Estate: The coffee estate is on the slope above Alajuela, on the way down from Poás. You follow the bush to the cup, then you leave. Two hours is enough.
- Atenas: A valley town with coffee on the hills and milder air than the city. The square is the stop. There is no single marked summit.
