IllustrationIruelas rises from El Burguillo reservoir into the eastern mountains of Gredos.
Iruelas rises from El Burguillo reservoir into the eastern mountains of Gredos. Its protected landscape spans El Barraco, El Tiemblo, Navaluenga and San Juan de la Nava. The lower valley offers a manageable introduction; the high Puerto de Casillas routes belong to a different kind of outing. Iruelas has its own nature-reserve designation, separate from the Sierra de Gredos Regional Park.
Forest habitat, especially that of the cinereous vulture and Spanish imperial eagle, is central to its conservation story. Las Cruceras adds a human dimension: resin and timber supported the settlement, and former industrial buildings became a place to explain the landscape. Start here to understand why protecting a tree can also mean protecting a bird.
The July 2026 fire changed parts of the reserve. Older photographs, descriptions of continuous shade and wildlife counts may no longer reflect what you encounter. Let the areas that staff confirm are open shape the visit. Unlock an interactive field guide for this spot: get the Snappit app to identify nature on the go.
Declared in 1997, the reserve protects the cinereous vulture, imperial eagle and their habitat among its priority values. Las Cruceras recalls an earlier forest economy: buildings used for resin and timber work were reused for rural tourism and interpretation. The park house opened in 2006. Its setting is a reminder that this forest’s history includes both livelihoods and conservation.
Begin at Casa del Parque Las Cruceras, then choose the Senda del Enebral if staff confirm it is open. For a longer walk, ask about the separate Siempreverde starting area and its botanical or Cerro de las Víboras paths. Bring binoculars and make time for the resin-working story.
Summer heat and fire restrictions can override walking plans. Autumn 2026 brings recovery works and special arrangements at El Castañar de El Tiemblo. The park house’s published calendar closes January and February; full hours appear below.
The park house and Enebral have documented accessible design, including firm surfaces and wooden walkways. Ask about their condition after the fire. Other paths need a separate assessment.

This 0.5 km circular path begins beside the park house, linking the juniper setting with views towards the reserve and El Burguillo. Once access is confirmed, it is the simplest first-visit choice. Allow 25–45 minutes with stops; the operator’s 15-minute figure is a walking estimate.
Designed with firm ground and wooden walkways. Check the whole circuit and parking approach, as one damaged section could interrupt wheelchair or pushchair access.
Start at Siempreverde, near the camping area, separately from the park house. The botanical booklet describes a descent past labelled plants towards the road used for the return. The published 0.6 km covers the linear path, not a traffic-free loop. Allow 30–45 minutes including stops, plus any additional return time staff advise.
The descent and road return need particular assessment with small children, pushchairs or limited mobility. Low difficulty does not establish step-free access.
Also starting at Siempreverde, this 3.6 km circular hill walk has a published walking time of 75 minutes; allow 1½–2 hours with pauses. The operator describes a bird-observation point. Before including it, ask whether both the circuit and the observation structure are usable after the fire.
A hill walk, with surface, gradient and obstacles to check. Its published low rating is not a wheelchair-access statement.
From Puerto de Casillas, this higher path heads towards an old snow-storage building. The operator lists 4 km, one hour and a 40 m height difference; check the complete return distance and time before choosing it. Access to the pass is a separate approach, so the published hour is not a reservoir-to-mountain outing.
A mountain path with weather exposure, not an extension of the accessible Enebral circuit. Suitability depends on conditions and the walker’s experience.
Confirm opening and Enebral access before leaving home. Begin with the park house, then take the small circuit if its current condition suits everyone. Return to the centre area for a break. Leave the high mountain routes for another visit.
After the initial park-house check, choose the botanical path or the longer Víboras circuit at Siempreverde. Establish parking and the return arrangement before moving there. Include time for a cold picnic in a permitted place. If the path is unavailable, keep to the centre visit or postpone.
At Las Cruceras, ask which displays explain resin collection and the settlement. Photograph buildings and their setting from public areas. Linking the old industry with the surrounding trees makes a rewarding visit even when outdoor access is limited.
For a mixed-age group, make the park house the main event and a short permitted path the bonus. Investigate one question together, such as why a vulture needs forest. A snack after the circuit gives children a clear endpoint.
Fit a few quiet minutes of sky-watching into the walk. Keep paths clear, leave drones and recorded bird calls out of the plan, and enjoy the setting even when no large bird appears.
If open, the interpretation centre can be the whole wet-weather visit. Exhibition renewal was announced in March 2025; ask what is available now. Postpone outdoor walking in heavy rain or strong wind, particularly near damaged trees or working areas.
An enormous, dark bird with broad, fairly straight-edged wings is a useful identification starting point. The reserve has a long-documented breeding association with this species, but old colony counts should not be taken as a postfire census. Use binoculars from an open, permitted place and compare the silhouette, without following a bird towards the forest.
Maritime pine, also called resin pine locally, connects the woodland with the history of Las Cruceras. The interpretation gives a reason to notice bark, cones and the old practice of resin tapping. Learn the story before walking, then look only from currently permitted paths.
Enebral means a place of junipers. The reserve’s botanical descriptions identify prickly juniper in the warmer lower valley. Where access allows, compare this low woodland with the mountain slopes beyond; the sharp change in elevation helps explain the variety of habitats.
Mountain streams drain towards El Burguillo, so the wooded slopes and reservoir margin are connected. This is why a visit close to the water can introduce an upland reserve.
The Pozo de la Nieve recalls the storage of mountain snow for later use. It tells a different working-history story from resin, but requires the separate Puerto de Casillas outing.
The 1997 designation names the cinereous vulture and imperial eagle as priority values. Their habitat deserves quiet and protection whether or not the birds appear during your visit.
Mild days suit a short permitted walk. Ask about current nesting restrictions without seeking nest locations; dates copied from an old itinerary are not a reliable guide to the areas open this season.
Start early where access allows, carry extra water and shorten the outing in heat. Do not light fires or bring a barbecue. Check any fire alerts or road restrictions before leaving.
The municipal site announces exceptional postfire visits from 10 October to 31 December on Saturdays, Sundays and public holidays, with advance tickets. Access is by private vehicle only, with no visitor bus or pedestrian access, and 35 vehicles per time slot. Weekday access is discouraged because work restricts the approach. Check the current booking terms before making plans; this arrangement does not reopen the rest of Iruelas.
The park house closes in January and February under the published calendar. Plan an early return in short daylight, and heed the operator’s warning against Cerro de la Escusa with snow or ice.
Casa del Parque Las Cruceras is in Poblado de Las Cruceras, El Barraco. Contact +34 918 627 623 or [email protected] for current access and guided visits. Ask about booking or fees for a particular activity.
January and February: closed. March–June and September–20 December: normally Thursday–Sunday, 09:00–15:00. July and August: normally Tuesday–Sunday, 09:00–15:00. The calendar adds 6 April, 12 October, 2 and 9 November, and 7 and 8 December, with 20 December shortened to 10:00–14:00. It lists closures on 29 May and 4 July. Confirm the date you need, particularly during recovery or building work.
Bring drinking water and food. Ask which toilets and nearby services are available that day; old campsite details are unreliable after the fire. The Las Cruceras operator reports its houses are operating, but confirm your own accommodation or meal arrangements directly.
Use the N-403 and the Valle de Iruelas turn near the bridge over El Burguillo, then follow the approach to Las Cruceras. Set the destination to Casa del Parque Las Cruceras. Park only in an authorised area, leaving access clear for residents and recovery crews.
A bus to El Barraco or El Tiemblo should not be assumed to reach the park house. Check onward transport to Las Cruceras and arrange the return before committing to the trip. Avoid a plan that depends on walking a road verge from the N-403.
Do not accept a navigation shortcut through restricted forest tracks. Puerto de Casillas and El Castañar have separate approaches; neither is a drive-through connection from the lower-valley walk.
Specialist access information records connected accessible buildings, compact surfaces, adapted toilets and the Enebral walkways. Ask about the complete parking-to-door journey, working toilets, damaged sections and diversions. Explain your mobility equipment and assistance needs so staff can advise on the present arrangement.
Enebral’s accessible design does not describe the botanical, Víboras or mountain routes. With a buggy or limited stamina, choose a centre-only visit unless staff can confirm a suitable continuous outdoor path.
The reserve was affected by the July 2026 wildfire. Before travelling, ask Casa del Parque Las Cruceras to confirm access to the exact path you want, including any nesting or forestry restrictions and the condition of surfaces and signs. The published routes below should not be assumed to have reopened after the fire. If access cannot be confirmed, postpone the walk; an old track on a walking app is not permission to enter.
Each card links to a full Explore page with photos, traits, and fun facts.
Start with the big picture, then zoom in to explore individual wildlife observations around this place.
Before setting off, ask the park house which named paths and approach roads are open that day.
Carry drinking water and a cold picnic; do not rely on fountains or catering along a walk.
Wear grippy footwear even for short paths, and take an extra layer for exposed places.
Stay behind barriers and out of burned slopes, forestry work areas and restricted forest tracks.
Use binoculars without approaching nests, playing calls, feeding birds or sharing sensitive locations.
Keep dogs under close control and follow posted requirements; check indoor admission separately.
Leave plants, cones and other natural material where they are, and take rubbish home.
Download your planning information before arrival and keep the emergency number, 112, available.
