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

These cozy, comfortable, and simple rooms allow you to sleep as close as anyone should to a volcano—it's the only hotel inside Arenal Volcano National Park and less than two miles away. Stellar views and outdoor activities are what the place is all about. The facility was founded by Smithsonian researchers and is fairly rustic, though after a hike on the 11 km (7 miles) of well-maintained trails, you can take a dip in the infinity pool and Jacuzzi, which face tall pines on one side and the volcano on the other. With more than 400 species of birds and 870 acres of private rainforest, this property is a dream for bird-watchers and those who seek peace and quiet. Other activities include complimentary guided hikes to the waterfall, horseback riding, or relaxing at the spa. Five of the rooms are wheelchair-accessible, as are a couple of miles of the property's trails. The dining room, which serves tasty and hearty food, has great views of the volcano and lake. A separate building contains a few spartan budget rooms.

Tucked into the mountainside, the main lodge with the restaurant and bar has a decidedly sophisticated feel, with spectacular views of the Pacific in the distance. Two-story suites are spacious, simple, and beautifully appointed. In addition to the main lodge, there are stand-alone bungalows, including a family suite with three bedrooms and two baths. The attentive staff is like that of a much pricier place, doting on you, knowing your likes, and helping with every last detail. Don't miss sunset happy hour with expertly crafted cocktails, or the restaurant with meals well suited to the epicure. Entrance to the Agouti Reserve with a 4 km (2½ miles) nature hike is included with your stay.

Reminiscent of a ski lodge, this longtime favorite has extremely comfortable and stylish rooms with vaulted ceilings and great views. The bar is positioned around a huge but cozy lobby fireplace, and the outdoor heated pool is a perfect place to unwind after a day of tromping through the reserves. The exceptional El Jardín Restaurant, with its menu of Garden, Ocean, and Land options, uses locally grown vegetables and dairy from the Monteverde milk factory. Rooms are situated along a long corridor, which tends to carry hallway noise; Nos. 201 and 207 have the most privacy. Guests are advised to keep their balcony doors closed, because monkeys have been known to ransack suites.

If you fancy toucan-spotting from your room or the deck of your bungalow, Chachagua will be right up your alley. Each room has a pair of double beds, an outdoor table, and nice showers enclosed in large, reflective windows where birds gather to watch their reflections while you bathe. Only deluxe bungalows have TV and plunge pools, but if you fancy a dip, there's a series of natural spring-fed pools leading to one of the two outdoor restaurants and bar. For complete isolation, request a room facing the rainforest. An open-air restaurant serves an organic menu. The lodge is 3 km (2 miles) up a rough track—4WD is a must in rainy season—on the road headed south from La Fortuna to La Tigra. Do not attempt arriving after dark or during heavy rains since the river crossing becomes impassable and roads are poorly marked.

From the villas to the farm to the on-site hot springs, kids and adults alike are enthralled by this peaceful property. The lush and lovely well-kept grounds have volcano views and include an agua fria (cold water) pool for splashing around as well as multiple tranquil hot springs to relax. There is a spa, bar, and restaurant. The farm-fresh eggs (you can collect them yourself) make for a hearty and delicious breakfast.

Whether whiling away the mornings on the porch amid the toucans, trekking to the river, or spotting nocturnal creatures on night hikes, nature lovers will be enthralled with the stilted cabins of this 10-acre property in the trees. With nice beds and air-conditioning, the basic cabanas, elevated on stilts, are level with the forest canopy, where you get a bird's eye view of the, well, birds, and Costa Rica's other plentiful flora and fauna. The property is quite a drive from the sights, but they're a relative bargain and friendly staff are a nice bonus. There's a minimum two-night stay.
