Guanacaste is the northwest corner of Costa Rica, a dry region of beaches, cattle country and volcanic uplands that stretches along the Pacific coast toward the Nicaraguan border. Most all-inclusive resorts here sit on the coast, particularly around the Papagayo Gulf, and many guests could happily stay put. The reason to leave is that the surrounding region offers national parks, wildlife and small towns that a resort week does not touch. This guide covers the main options and the planning points that matter for each.

Understand the seasons first

Guanacaste has a pronounced dry season and a green season. The dry season usually runs from about December to April, with sunny days and dusty hills. The green season, roughly May to November, brings afternoon showers, lush landscapes and lower prices. Both are good for different reasons, but outings behave differently. Trails are drier and easier in the dry months, while rivers and waterfalls are fuller in the green months. Our guide to all-inclusive resorts in Costa Rica and what differs explains how the seasons shape a stay.

Rincon de la Vieja National Park

This is the best-known inland destination in the region. The park surrounds an active volcano and offers trails past fumaroles, bubbling mud pools, streams and forest, with waterfalls and swimming spots in some areas. Access to the volcano summit is restricted at times for safety, so check the park’s current status before you travel. Many visitors combine a morning hike with canopy tours, horse riding or hot springs run by private operators nearby. The drive from the Papagayo coast is typically about an hour and a half to two hours each way, so plan a full day and start early.

Santa Rosa National Park and Playa Naranjo

Santa Rosa protects dry tropical forest, historic sites and a remote stretch of coast. The beaches here, including Playa Naranjo, are known to surfers, and access can involve rough tracks, so a guided tour or a high-clearance vehicle is wise. It suits guests who prefer wildlife and history to a beach day. Bring plenty of water, as there is little shade on some routes.

Playa Conchal and the Papagayo beaches

Playa Conchal is known for its sand, which contains crushed shells and gives the beach its name. It is among the more photographed beaches in the region and can be reached from several resorts, either on foot along the shore or by a short drive. The Papagayo Gulf also has sheltered coves that are suitable for snorkelling and paddling on calm days. Always ask the resort about current water conditions, because Pacific beaches can have strong currents, and learn what the beach flags mean before you swim.

Tamarindo and the small coastal towns

Tamarindo is the largest beach town in the region, with restaurants, surf schools and shops. It is livelier than most resort areas and gives a change of pace for an evening meal. Smaller towns along the coast offer a quieter version. Take local currency or a card, as small businesses may prefer one over the other, and check the exchange rate offered before you pay.

Wildlife, boat trips and turtle nesting

Palo Verde National Park, farther inland, is known for wetlands and birdlife and is usually visited with a guide on a river boat. Along the coast, sea turtle nesting takes place on several beaches. At Ostional, olive ridley turtles nest in large numbers in mass events known as arribadas, which occur through the year with a peak in the wetter months. Because these are wild events with strict local rules, only visit with a licensed local guide, and do not expect a guaranteed sighting. Responsible operators will tell you this plainly.

Planning and safety points

• Book with licensed guides for parks, volcano areas and turtle viewing. Ask the resort desk, but compare it with independent operators.
• Allow for road conditions. Some routes are unpaved, and travel times can be longer than the map suggests.
• Pack for sun and rain. A light rain jacket is useful in the green season, and reef-safe sunscreen and a hat are useful all year.
• Carry identification and any medication you need for the day, and check the rules for carrying prescriptions on a resort trip.
