Step 1: Reserve Permit
Through SINAC (Sistema Nacional de Áreas de Conservación), which can be booked online on their platform.
Step 2: Reserve Accommodation
Additionally, hikers must reserve a spot separately at the Base Crestones Refuge, the sole accommodation near the summit, which offers basic lodging about 5.5 kilometers from the peak. It is especially important to book several months in advance during the dry season, when hiking is most popular due to favorable weather. Permits can be obtained up to 6 months in advance. During the wet season, permits can be obtained up to a couple of days in advance. Reservations can be made up to 6 months in advance. You can book up to 6 people per group, and same-day permit bookings are no longer available.

Step 3: Register In Person
Finally, it is important to note that one must register the day before entering the park at the National Park Office in San Gerardo. Given that registration closes at 4:00 PM every day, it is very important to plan your arrival in San Gerardo well in advance to avoid missing the registration window.

Physical Preparation for the Cerro Chirripó Hike
Hiking Chirripó is physically demanding, requiring a good level of fitness due to the steep 2,500-meter (8,200-foot) ascent and a total distance of 40 kilometers.
Prior experience with long hikes or high-altitude trekking is highly recommended. Since the summit stands at over 3,800 meters, altitude sickness is a real concern. To minimize risk, it is advisable to spend time in high-altitude regions beforehand to acclimate. Whether you are hiking in the dry or rainy season, being in good physical shape is crucial for completing the journey safely.
A successful Cerro Chirripo hike requires:
- Strong cardiovascular endurance
- Leg and glute strength
- Knee preparation for descent (trust me, I never feel a pain like that)

The descent is often more painful than the ascent because of constant downhill travel over rocks.
Training 8–12 weeks prior is strongly recommended.
