Is Barragem de Montargil good with a dog?

Mixed, in our experience with Aba.

Barragem de Montargil is a beautiful lake. It still wasn't one of our favourite lake spots in Portugal. Access was harder than we expected, and we only found one short hike. At the end of May we were covered in bites, and we pulled several big ticks off Aba after every walk. Aba loved the forest and the warm, muddy water. For us, it was better to look at than to spend time at.

With a dog

Water for the dog
Aba got to swim in muddy water. It already felt very warm at the end of May. Check the water quality before you let your dog swim.
Shade and heat
In many places the forest comes right down to the water, so there is natural shade on the walk.
Paths and terrain
The ground was easy on paws, and we found no broken glass. We only found one short hike, and it didn't feel like a place for long walks along the shore. Two of the public access points we found meant driving a while on very bumpy dirt or forest roads.
Watch out for
Aba had tick protection, and we still pulled several big ticks off him after each walk. The mosquitoes and other biting insects went for us too, even through strong insect repellent.

A beautiful lake that's hard to reach

Montargil is a well-known lake destination, mostly for people who like water sports. On paper, it's exactly the kind of place we usually love. The lake is beautiful. There's forest, soft hills and lots of water. But access was more limited than we expected. Many of the easiest spots on the lake seem to belong to campsites, hotels or other private facilities. We found only a few public access points, and two of them meant driving a while on a very bumpy dirt or forest road.

For walking, we only found one fairly short hike. Compared with other lakes we've visited, this didn't feel like a place for long walks along the shore.

Insects, ticks and warm water

In many places the forest comes right down to the water. It looks stunning and gives some natural shade on the walk. But at the end of May we were eaten alive. We wore strong insect repellent, and the mosquitoes and other biting insects still went for us. Aba had tick protection, and we still pulled several big ticks off him after each walk. If you come here with your dog, check them carefully afterwards.

The water already felt very warm at the end of May. Aba had a fantastic time anyway. He had a forest full of smells, muddy warm water to swim in, and the odd fish jumping out of the water. For us, the bites, the ticks, the limited access and the state of the water made Montargil beautiful to look at, but not much fun to spend time at.

Birds, then the walk itself

If you like birds, bring a big lens. Montargil is known for birdwatching. I saw black kites hunting and lots of other interesting forest and lake birds. So it's a beautiful lake, great for birding and probably great for water sports, which we didn't try. As a place to walk and swim with a dog, it wasn't one of our favourites. The rest of the video is the walk with its original sound.

Good to know

  • Bring something to remove ticks. Check your dog carefully after every walk, even if they have tick protection.
  • Bring strong insect repellent for yourself. At the end of May it only helped so much.
  • Check the water quality before you let your dog swim.
  • Some of the public access points meant driving a while on very bumpy dirt or forest roads.
