Escaping Valencia for a Day
Valencia is a city that rewards those who leave it. Within 1.5 to 2 hours of the city centre, the landscape transforms completely — from Mediterranean coast to mountain canyon, from river delta to medieval hilltop fortress, from botanical garden to underground cave system.
The day trips available from Valencia cover a remarkable range: active mountain hiking with thermal pool swimming, boat tours through subterranean rivers, multi-village cultural circuits along the Costa Blanca, and some of the most dramatic natural landscapes in eastern Spain. Most tours include round-trip transport from central Valencia, making them entirely self-contained — no rental car, no logistics, just an early morning departure and a late afternoon return.
The options below cover five fundamentally different experiences, suited to different travel styles and fitness levels.
Montanejos: Hike the Mijares Canyon & Swim in Thermal Pools
Montanejos is the definitive natural day trip from Valencia — 4.7/5 from 2,452 reviews, and the most-reviewed outdoor excursion in the region. The village sits at the bottom of a dramatic limestone canyon carved by the Mijares River, roughly 100km northwest of the city in the province of Castellón. The combination of challenging canyon hiking and year-round thermal swimming makes it uniquely rewarding in any season.
The Hike: Mijares River Canyon
The guided hike follows the Mijares River for approximately 9 kilometers (shortened to 5-6km in summer) through a narrow gorge with sheer limestone walls, native pine forest, and panoramic viewpoints. The terrain is moderate — some steep sections at the start, rocky paths throughout — and the trail involves river crossings in places.
The hike's signature landmark is El Chorro: a natural water jet that releases approximately 300,000 litres per minute from the rock face. Even when the flow varies seasonally, the force of this underground spring emerging directly from the cliff is striking — one of the more unusual natural phenomena in the Valencia region.
The Thermal Pools: Fuentes de los Baños
At the end of the hike, the Fuentes de los Baños thermal springs are where the Mijares River receives a constant injection of mineral-rich underground water, maintaining the pool temperature at 23-25°C year-round. The springs have been in use since at least the 10th century, when Moorish settlers built a bath complex here — the ruins of which are still visible nearby.
Participants have approximately 1.5 hours of free time at the pools — enough to swim, dry off, eat a packed lunch by the river, and explore the small village. A bar near the pools serves cold drinks and basic food.

- Not suitable for: Children under 14, pregnant travelers, serious medical conditions, mobility issues

Best Full-Day Nature Trip from Valencia
From Valencia: Montanejos Hiking Tour & Thermal Pools
A full day in the Mijares River canyon — 9km guided hike through dramatic limestone gorge, the Chorro natural water jet, and 1.5 hours of free time at the 25°C thermal pools. Round-trip bus from Valencia included. Valencia's most popular outdoor day trip, rated 4.7/5 from 2,452 reviews.
Book Montanejos Tour on GetYourGuide →Cueva de Sant Josep: Underground River Boat Tour
The Cueva de Sant Josep (Coves de Sant Josep) in La Vall d'Uixó — just 50km from Valencia — is one of the most unusual natural attractions in Spain: a network of limestone caves containing one of the world's longest navigable underground rivers. Visitors board small flat-bottomed boats and glide through 1.5 kilometers of illuminated cave chambers, with stalactites and stalagmites reflected in the dark water beneath.
This is a half-day experience rather than a full-day trip, making it natural to combine with other Valencia activities. The boat tour is accessible for all ages and fitness levels — no hiking required, no steep terrain. It is particularly recommended for families with younger children, travelers who want a unique natural experience without physical exertion, and those for whom Montanejos is too demanding.
Two Booking Options
Two versions of the cave tour are available on GYG — choose based on your preference:
- t431994 — Cueva de Sant Josep Boat Tour with Guide (4.6/5 · 2.319 reviews): The most-reviewed option. Includes transport from Valencia and a guided boat tour through the caves. The larger review count reflects years of accumulated bookings.
- t481345 — Caves of San José Tour + Guide & Entry Ticket (4.7/5 · 308 reviews): Slightly higher-rated alternative, also with transport, guide, and entry included. The newer listing with fewer but more recent reviews.
Both cover the same core experience — the difference is primarily in the specific tour operator and departure logistics. Check availability for your preferred date on both listings.

Book Alternative Cave Tour →Altea, Guadalest & Algar Waterfalls — Full-Day Costa Blanca Circuit
This full-day excursion covers three completely different landscapes and experiences in a single outing — rated 4.6/5 from 307 reviews. It is the most visually varied day trip available from Valencia, combining a Mediterranean coastal town, a dramatic medieval mountain fortress, and a protected waterfall system in the same journey.
The Three Stops
- Altea — A whitewashed hilltop town on the Costa Blanca with cobbled streets, artisan shops, and the iconic blue-domed church. Sea views from the hilltop. Free time to explore, eat, or walk down to the beach below the old town.
- Guadalest — One of Spain's most dramatically situated villages: a 10th-century Moorish fortress village perched on a rocky needle above a turquoise reservoir, accessible only through a tunnel carved through the rock. The medieval castle, cobbled streets, and panoramic views over the mountains and water are consistently described in reviews as breathtaking.
- Algar Waterfalls (Fuentes del Algar) — A protected natural wetland area with cascading waterfalls and crystal-clear natural pools in lush vegetation. Swimming is possible in the pools. The paths involve uneven terrain and some climbing — not suitable for those with serious mobility restrictions.
3 Destinations · Full Day · Coast + Mountains
From Valencia: Altea, Guadalest & Algar Waterfalls
A full-day Costa Blanca circuit: Altea's whitewashed hilltop old town, Guadalest's medieval cliff-top fortress with turquoise reservoir views, and the Algar Waterfalls natural pools. Three completely different experiences in one day, with transport from Valencia and a knowledgeable guide throughout.
Book Altea + Guadalest + Algar →Stay in the City: Cathedral, St Nicholas & Lonja de la Seda
Not every day has to be a full-day trip. For travelers who want to go deeper into Valencia itself rather than leave the city, the guided tour of the Cathedral, Church of Saint Nicholas, and La Lonja de la Seda offers 3-4 hours of concentrated cultural immersion in the Old Town.
The Church of Saint Nicholas — Valencia's Sistine Chapel, with 2,000m² of Baroque ceiling frescoes — alone justifies the decision to stay. Rated 4.7/5 from 500+ reviews, with skip-the-line entry to all three monuments included. A natural choice for a rainy day, a rest day between outdoor excursions, or a final morning before departure. See the full Walking Tours guide for more options.
Stay in Valencia · Half-Day · All Weather
Valencia Cathedral, St Nicholas & Lonja de la Seda Tour
Skip-the-line entry to three of Valencia's finest historic interiors in 3-4 hours: the Cathedral with the Holy Grail, Saint Nicholas (2,000m² of Baroque frescoes), and the Gothic Silk Exchange. The best alternative to a day trip for a rest day, bad weather, or a final morning in the city.

Practical Tips for Day Trips
What to Bring for Montanejos
When to Go
- Best months overall: May, June, September, October — warm enough for swimming, cooler for hiking, fewer crowds at the pools
- Summer (July-August): Hot (35°C+) but the thermal pools are the most inviting. Arrive early at the Algar Waterfalls to avoid peak crowds. The hike is shortened to 5-6km in summer
- Winter (November-March): The thermal pools are still 25°C — a surreal contrast to air temperatures. The hike is at its most dramatic with high water in the river. Fewer tourists everywhere
- Weekdays vs weekends: Montanejos is significantly less crowded on weekdays. The Algar Waterfalls on a summer Saturday can be very busy
Book in Advance
All tours include coach transport with fixed departure times — places are limited. Book at least 3-5 days in advance in peak season (July-August) and over Spanish public holidays. Free cancellation up to 24 hours before departure on most tours gives you flexibility without risk.
