About Liberia

Liberia, Costa Rica, is a relaxed gateway to Guanacaste’s sun-soaked beaches and volcanic landscapes, with easy access to both the Pacific coast and inland nature. In April, the region is typically hot and mostly dry, often marking the tail end of the dry season, with daytime highs commonly around 30–35°C and low humidity compared with the greener months.

Spend a day hopping between nearby beaches like Playa Hermosa or Playa Panamá, then head inland for a soak in hot springs near Rincón de la Vieja Volcano. Wildlife watching is rewarding in this season, and the clear skies make for excellent sunset views and stargazing after an evening of local Guanacastecan cuisine.

Tips for This Route

• Porter’s Ottawa–Liberia nonstop is on an Embraer E195-E2; the 2–2 layout means no middle seats, and the “PorterReserve” front cabin has noticeably more legroom for the 5h50m hop—worth it if you’re tall.
• Don’t count on seatback screens: bring downloaded movies/podcasts and a power bank, then lean into Porter’s free beer/wine and decent snacks (but eat a real meal before boarding).
• At YOW, Porter’s gates can be a walk; show up early so you’re not sprinting to board, and aim for the left side of the plane for nicer Pacific-coast views on arrival into LIR.
• Liberia (Guanacaste) is hotter and drier in “high season” (Dec–Apr) and can be dusty; pack a light layer for the cold cabin, then change quickly after landing.
• In Guanacaste, small bills matter: carry some colones for tolls/parking and tip 10% only if it’s not already included as “servicio” on the bill.
