This route was planned by komoot.
No, this route, despite being categorized as 'jogging' on komoot, is generally not recommended for casual jogging or beginners. It is considered a hard, highly technical hike requiring good physical fitness, sure-footedness, sturdy footwear, and prior alpine experience. The terrain includes significant elevation gain, scrambling sections, and uncomfortable karst pavement (lapiaz).
The terrain is challenging and diverse, characterized by a dramatic karst landscape within the Itxina Protected Biotope. You'll encounter a 'labyrinth between mountains full of chasms and caves,' with a 'tortuous territory of sinkholes, dolines, and lapiaces.' The route consists primarily of unpaved, natural, and alpine sections, with rocky, uneven ground that makes it unsuitable for typical jogging.
This route offers several spectacular natural highlights. You will pass by the famous Ojo de Atxular, a natural gateway with panoramic views. The trail also leads to the Axkorrigan Occidental Summit (1095 m), offering breathtaking views over the Itxina Karst. Additionally, you can visit the impressive Supelegor Cave, known for its large entrance and mythical connections.
Specific parking details for this exact trailhead are not provided in the available information. However, trails in the Gorbeia Natural Park often have designated parking areas near popular access points. It is advisable to check local resources or maps for the most convenient and official parking locations before your visit.
The Itxina Protected Biotope is located within the Gorbeia Natural Park. Generally, there are no entrance fees to access the natural park itself. However, for specific activities or larger groups, it's always best to check the official websites of Visit Biscay (visitbiscay.eus) or Basque Country Tourism (basquecountry-tourism.com) for any updated regulations or permit requirements, especially for sensitive areas or guided tours.
Given the technical nature of the terrain, especially the steep and rocky sections, it's best to undertake this route during dry conditions. Wet ground can make the scramble and steep channels particularly hazardous. Spring and autumn generally offer pleasant temperatures, but always check the weather forecast for the Gorbeia Natural Park before you go.
While many trails in natural parks allow dogs, the highly technical and potentially hazardous terrain of this specific route, including scrambling and navigating uncomfortable karst sections, might not be suitable for all dogs. If you do bring a dog, ensure it is well-behaved, physically capable of handling difficult terrain, and kept on a leash as per general park regulations.
Given the trail's difficulty and terrain, you should bring sturdy, ankle-supporting hiking boots with good grip, appropriate clothing for varying weather conditions, plenty of water and snacks, a map and compass or GPS device (as straying from the path can be problematic), and a headlamp or flashlight if you plan to explore the Supelegor Cave.
Yes, particular caution is advised if the ground is wet. The ascent to Axkorrigan involves a steep channel of rock and grass which becomes especially discouraged and dangerous in wet conditions. The karst terrain can also be very slippery when wet. Always check the weather forecast for the Gorbeia Natural Park before starting your journey.
Yes, this route also passes through sections of the [CIMA BI02] Larreder - Pagomakurre and the Areatza - Pagomakurre trails.
Yes, the route allows for visits to notable caves like Supelegor Cave. Supelegor is celebrated for its impressive, large entrance and accessible interior. A flashlight or headlamp is highly recommended if you plan to explore inside.
