Resorts in La Fortuna, Costa Rica, line the lower slopes of Arenal Volcano, with naturally heated hot spring pools and rainforest views. The Springs Resort & Spa at Arenal is a top-rated family-friendly pick, offering 28 hot spring pools, five restaurants, a full-service spa, a wildlife preserve, and access to Club Rio for river tubing and horseback tours. The adults-only Royal Corin Thermal Water Spa & Resort delivers quieter hot spring pools, volcanic clay treatments, and a location less than 12 km from Arenal Lake. Both properties include free parking, and both score 88 or higher on guest reviews.
These are premium resorts, so set a higher budget than La Fortuna's average hotel. For first-timers, the Arenal Volcano Road between downtown La Fortuna and the national park puts you close to both resorts and trailheads. Book early for Christmas Eve or New Year's Eve: The Royal Corin charges a mandatory dinner on those dates. A car helps you explore, though The Springs offers an airport shuttle for a fee and free on-site parking. For added adventure, ask the resorts about Club Rio's rafting and rappelling trips.
