6 Best Hotels in Arenal, Monteverde, and the Northern Lowlands, Costa Rica

Perched canyonside with views of the forest and the volcano beyond, these spacious, modern cabins of stone and wood below soaring ceilings and massive windows are cozy, private, and comfortable. Your villa includes free minibars featuring local beer and kombucha, a private deck with a plunge pool, indoor/outdoor showers, a huge high-end gym, complimentary yoga classes, a swim-up bar for socializing, and unparalleled service. The breakfast with a personal French press of coffee is mostly grown on-site and will fill you up until dinner.

Scattered over expansive grounds are freestanding casitas, villas, and "tents," all tastefully decorated with dark-wood furnishings and equipped with luxurious touches like indoor-outdoor showers, four-post canopy beds, plasma TVs, and whirlpool tubs. Rooms fall into three categories (suites, casitas, and villas) but are similar in design with an eclectic mix of imported decor ranging from Italian crystal chandeliers to Balinese hand-carved furniture. The wood-plank floors and ceilings made from sugarcane reeds add a natural touch. The adults-only villas are at Naraya Springs, an exclusive section of the resort connected by way of a 230-foot jungle bridge. Double the rate of the casitas, villas have private plunge pools and complimentary extras like minibars, Wi-Fi, laundry service, and yoga. Although lacking volcano views, villas are extremely private and have their own reception area, spa, and pool. Only half of the casitas and suites have volcano views. The highest-end is the tented camp, large luxury "tents" have soaring ceilings, soaking tubs, breathtaking vistas of the volcano from the suites and private plunge pools, walk-in closets, your choice of breakfast served on the patio, and every amenity (daily laundry service is included). There are cascading termales, thermal pools heated by the natural springs, and the spa has open treatment rooms so you can hear the wildlife and rain during your massage. The resort's five restaurants offer tapas, international, Asian, Mediterranean cuisine, and even a wine bar, so you never have to leave the comforts of the grounds. Special packages are available for those who want meals included in the rate.

This is one of the closest properties to the volcano, with rooms boasting hydromassage Jacuzzis, sitting areas, jaw-dropping views, Juliet balconies, and nearly 700 square feet of space. High ceilings, almost too much space, and queen beds that face walls of glass are what set this property apart from competitors; but at night when the curtains are drawn, rooms can be rather dark and stuffy (electricity operates by key card). The beautifully manicured grounds make up for this minor pitfall, with streams, gardens, and thermal springs that cascade from the swimming pool down to the spa. Guests receive complimentary admission to the Titokú Hot Springs, located 6 km (4 miles) south of the hotel and 5 km (3 miles) north of La Fortuna.

With its own adventure park, hot-springs complex, and activities for all ages, this resort caters to both hotel guests and the outside public with day passes to its massive grounds. Near-perfect volcano views from individual balconies, a 14,000-square-foot spa, and rustically elegant rooms all contribute to a sense of well-being at this luxurious and remote retreat. The sky is the limit in furnishings (and price) as you work your way up to the suites and villas—additional rooms, arched sky-lighted ceilings, and hot tubs are among the amenities. Even the standard rooms have surround-sound speaker systems and huge balconies facing the volcano. Below the property is Club Río, an outdoor adventure park with kayaking, horseback riding, rock climbing, rappelling, hiking, and a wildlife preserve for rescued animals. Visitors are transported up and down the hill by shuttle bus, and many of the hot-spring pools are surrounded by the kind of artificial rocks and boulders you see in amusement parks.

At one of Central America's most relaxing and romantic resorts, it's the hot springs and lovely spa, coupled with attractive rooms, that customarily draw happy guests inland from the ocean. Most rooms have a terrace, all with either volcano or garden views. Luxurious touches include nightly turndown service, bathrobes, a minibar, a movie library, and free access to the hotel's hot springs (day passes for nonguests cost $89). Updated rooms provide respite after a day's adventuring. As the most romantic and beautifully designed hot-spring facility in the area, the 20 pools tend to get crowded with outside visitors. For a break from the public, hotel guests have access to the Shangri-La Gardens, an exclusive adults-only hideaway. The hot springs and spa are actually 300 meters east of the hotel; you can either walk from your room or take the complimentary shuttle.
