La Moleta and Ibón de Iserias Circular Trail

This challenging hike typically takes around 7 hours and 48 minutes to complete. However, given its difficulty and significant elevation gain, it's wise to allow extra time for breaks and enjoying the panoramic views.

No, this trail is classified as 'difficult' and is not suitable for beginners or families with young children. It requires very good fitness, sure-footedness, sturdy shoes, and some alpine experience. The section to the summit of La Moleta and the Ibón de Iserias is particularly demanding.

The trail typically starts from Canfranc Estación. Parking is generally available in the vicinity of the Canfranc International Railway Station, which serves as a convenient starting point for many hikes in the area.

The terrain is highly varied and challenging. You'll encounter a 'challenging vertical kilometer' ascent via El Carretón through dense forests. As you gain altitude, the path transitions to open, rocky sections with loose stones and narrow passages. Some parts, especially above 2,000 meters, may even feature fixed chains or 'clavijas' to aid navigation. The descent often leads through the picturesque Izas valley with green meadows.

The route offers spectacular Pyrenean landscapes. Key highlights include the stunning, emerald-green Ibón de Iserias (also known as Ibón de Samán), a hidden glacial lake. You'll also pass by the Divina or Negras Waterfall and enjoy panoramic views from the summit of La Moleta, overlooking peaks like Midi d'Ossau and Collarada. The historical Canfranc International Railway Station is also visible from above.

The best time to hike this trail is typically during the warmer months, from late spring to early autumn, when the high mountain passes are clear of snow. It is not recommended in conditions of heavy snow or ice due to avalanche risk and exposure, as it requires alpine experience.

While specific restrictions for dogs on this exact trail are not detailed, given its 'difficult' classification, varied terrain including rocky sections and potential fixed chains, and the need for sure-footedness, it may be very challenging or unsuitable for many dogs. Always ensure your dog is fit for such demanding conditions and check local regulations regarding leashes and protected areas.

There is no mention of specific permits or entrance fees required to hike the La Moleta circular trail. However, it's always good practice to check for any updated local regulations before your trip, especially if visiting protected natural areas.

The trail passes by the Refugio Huerta Seséñas, which might offer some basic facilities or shelter. While there are natural water sources like the Divina or Negras Waterfall and the Ibón de Iserias, it's crucial to carry sufficient water for a hike of this duration and difficulty, as natural sources may not always be reliable or potable.

Given the trail's difficulty and high-mountain environment, you should pack sturdy hiking boots, appropriate layers of clothing for varying weather conditions (even in summer), rain gear, plenty of water, high-energy snacks, a map and compass or GPS device, a first-aid kit, and sun protection. Trekking poles can also be very helpful on the steep and rocky sections.
