It is undoubtedly a privileged place worth visiting, especially for its location within the natural park, its proximity to the beach, and its health tourism, as it is an underground source of thermal waters—with a considerable sulfur content—whose waters have traditionally been recognized as beneficial for treating dermatological diseases.

If you’re looking for a peaceful and scenic day out in nature, Marjal de Pego-Oliva Natural Park is a hidden gem worth exploring. It’s a beautiful wetland area located between the towns of Pego and Oliva on the Costa Blanca, full of wildlife, rice fields, and freshwater springs. 🚶♂️ What to Do There • Walk or cycle the trails: There are several easy routes, including wooden boardwalks over the marsh, great for families or casual walkers. One of the most popular paths is the Ruta del Bullent, a circular walk that brings you close to rivers, rice fields, and the famous natural spring. • Swim in the Font Salada: This is a warm natural spring (about 21–24°C all year) where you can take a dip. The water is known for its skin-healing properties. • Birdwatching: The area is rich in biodiversity, with herons, ducks, and even rare fish and turtles. Bring binoculars if you can. • Enjoy the peaceful views: There are viewing platforms offering panoramic vistas of the marshes and surrounding mountains. 🧭 Tips for Your Visit • Follow the marked trails to protect the environment and avoid getting lost. • Bring water and sun protection, especially in summer. • Respect nature: take your trash with you, keep noise down, and don’t disturb animals or plants. • Avoid weekends in high season if you prefer quiet – it can get busy, especially at the spring. 🚗 Getting There & Parking Access is easy from the N-332 or the CV-700. If you’re visiting Font Salada, note that parking has recently been restricted. There’s a new small car park nearby (Racó del Fuster), and the spring is a short walk from there.
