Costa Rica is sold to visitors with rental cars and private shuttles. It also has a public bus network that reaches almost everywhere for a fraction of the price, which changes the arithmetic entirely for one person.
The bus network
Extensive, cheap and reaching almost every town.
The trade-offs: journeys are slower, many routes require a change in San José, and schedules take some working out since information is not centralised.
Tourist shuttles are faster, door to door, and cost several times more — which for a solo traveller is several times more paid entirely by you.
A San José to La Fortuna bus costs a few dollars. The shuttle costs a great deal more.
Ask at your hostel which bus and from which terminal; San José has several and they are not interchangeable.
Where solo works
La Fortuna and Arenal — hostels, hot springs, waterfalls, and volcano trails, with everything bookable per person.
Monteverde — cloud forest, canopy walkways and night walks, all guided group activities.
Manuel Antonio — small, easy, with reliable wildlife.
Santa Teresa and Nosara — surf towns with a strong solo and long-stay scene.
Puerto Viejo on the Caribbean, cheaper and with a completely different culture.
Corcovado — requires a certified guide anyway, so joining a group is the only option and there is no solo penalty.
Activities price well for one
This is the structural advantage.
Rafting, canopy tours, guided hikes, night walks, diving and surf lessons are all per person and group-based.
They are also the main way solo travellers meet others, since everyone on a raft is in the same situation.
Eating alone
Sodas — small local restaurants serving casados, a plate of rice, beans, salad, plantain and a protein, for a few dollars.
They are where Costa Ricans eat, they are everywhere, and eating alone at one is unremarkable.
Hostel kitchens cover the rest, and supermarket prices are reasonable.
The costs
| Item | Solo daily |
|---|---|
| Hostel dorm | $15–30 |
| Hostel private room | $40–70 |
| Casado at a soda | $5–8 |
| Public bus between towns | $3–10 |
| Guided activity | $40–100 |
Activities are the main expense, not accommodation or food. National park entries add up too.
Safety
One of the safer countries in the region for independent travel, with the realistic risks being opportunistic theft and the sea.
Riptides are the leading cause of visitor deaths on Pacific beaches. Swim where there are others, and understand that the escape is to swim parallel to shore rather than against the current.
Do not leave belongings on the beach or visible in a vehicle.
Avoid walking alone at night in San José and in some coastal towns; take local advice.
Practical
Distances take longer than they look. Roads are mountainous and a 150 km transfer can take four hours.
Season: the Pacific side is dry roughly December to April; the Caribbean follows a different pattern with drier spells around September and October.
Spanish helps considerably outside the main tourist towns.
Book hostels ahead in the December to April high season.
