Klambratún is a multi-use park located right in Reykjavík, Iceland. You can see some of the iconic bits of the Reykjavík skyline from the park, such as the Hallgrimskirkja church. There is a short 14-hole disc golf course (recently expanded from a shorter 9) that plays in a "C" shape counterclockwise around three edges of the park.

This is a decent layout for beginners and rec level players just looking for an easy round. Holes range from 32 m (105') to 61 m (200') and typically have a couple of tree trunks to work around, and/or thicker bushes/brush in play on one side of the fairway or behind the basket. Although there are many holes that could be construed as "just a clear look at the basket", I felt that the designers did a good job using the natural obstacles that are available in the park. If you overthrow your ace attempt and it goes into the bushes, having to settle for par is likely - this happened to me on multiple holes.

The baskets are yellow banded DiscGolfPark models with the "Next Tee" arrows welded in the bottom. The course flows smoothly from hole to hole, so I didn't have any issues with navigation.

The tee pads are either small circular arrays of pavers, or plastic(?) mesh with stones inside it. One per hole. The mesh is the same stuff you can find at steep spots on maintained nature trails/scenic hikes all over Iceland, and I think it's really grippy and works fine here. Same with the paver arrays - no issues.

The tee signs are just little wood posts with the hole number affixed to them, but since there are no blind holes I didn't really mind.

There is a large kiosk/map between the parking lot and first tee. That parking lot is plenty large, despite the urban setting. The park has trash cans and benches available.

There are some multi-use concerns here. Hole 11 plays close to a soccer (sorry, football) field, and I was fortunate that practice ended just as I got to that tee. Walking paths are in play on a couple of holes.

With holes averaging only about 45 m (150'), the course will be way too short and easy for experienced players. It's also all flat terrain, and there are no water hazards in play. I felt like instead of expanding from 9 holes to 14, the designers could have just made the 9 holes slightly longer to fill a similar amount of space. This would still be a beginner friendly course if that were the case, but it might also be a little bit more appealing to more seasoned players. I finished 6 under and played bogey-free golf here without really trying too hard.

No practice basket, and I didn't see a restroom in the park. There is probably one inside what appeared to be a small on-site art museum, but I thought that might have an admission fee so I didn't try to go inside.

=== Disclaimer and Award ===
I'm an American from the state of Michigan who played 14 courses in Iceland while on vacation. My ratings and thoughts are therefore relative to the other courses I played in Iceland - but also the hundreds of US courses I have played. Furthermore, I use the entire 0-5 rating scale per DGCR standards. For example, a 3.5/5 may be seen as a negative on Amazon or UDisc - but here it really does mean "Very Good".

I am giving each course I played in Iceland an informal award, because every course has something special to offer.
This course's award is: Most Convenient Round.
This course is nothing amazing, and I wouldn't recommend going too far out of your way to play it. But if you live nearby or are visiting the area, the combination of in-the-city, available parking, and a quick round means this is likely a pretty easy one to add to your itinerary. It's definitely playable with one disc, for those tourists who are trying to pack light. Overall, not a bad place to spend 30 minutes and you can bring the non-DGers in your party too. I was between a 1.5 and 2.0 here, so let me call it a "strong" 1.5.

This was the last course I played out of the 14 mentioned above (we would pack up later the same evening, in order to catch our flight home the next morning). It made for a nice little encore to wrap up the disc golf portion of our trip. We plan on returning to Iceland one day, and I would recommend to all non-locals that you plan your own vacation here. If interested and starting to look into it, feel free to DM me as I'm happy to chat about logistics etc. Our Iceland vacation ranks high on our list of trips taken all-time, and the disc golf (overall, better than expected) was the icing on the cake!

-Can be played with one or two discs.
-Takes under 30 min to play
-Many aceable holes
-If played in the summer can play beyond 11pm
-Easy to find in a well labeled park
-Course Map at hole one
-Great tee pads

-Holes are similar but did well being in a city park
-If a lot at the park could be waiting for others to walk the paths
-Limited parking if the park is being used

This course now has 14 holes. I emailed admin but did not hear back from them. After 9 you will see 10 or just look at the sign before #1 to see entire layout.

-Tees are cobble stone, and while they are inconsistently shaped, they are good quality and adequate for what is needed at this course.
-There are posts in each tee pad that say what hole it is, but no par or distance.
-High quality DISCatcher baskets.
-Fairways are short grass with assorted walking paths as typical for a city park course.
-Extremely easy to navigate, the flow is intuitive, and tees are clearly visible from each basket.
-This is in a nice city park, and the course is pretty cookie cutter in terms of a typical city park type course, but there is a low amount of graffiti and garbage, so there is overall a nice vibe at this course.

-Not really any rough to get stuck in, other than the occasional bush.
-No elevation, or mounds, just flat.
-A couple trees in the fairways that add to the holes, but some shots are just 200' straight shots with a tree or two on the green.
-No OB, one Mando, on an easy course like this you need to have stuff like that to make it a little more difficult.
-Short distances, almost all holes are ace opportunities and most are pretty unchallenging because they are right there over flat ground with only a couple trees in the way.

This course is a fun activity to do in Reykjavik, my hotel was just over a kilometer away from this park, so I had to play it, and it was worth it.

-There is a good chance you will hit an ace
-Very easy to find
-Relatively easy to navigate, as the holes just loop around the perimeter of the course
-Only takes 45 minutes to play
-Is flat and walkable
-It is walking distance if you are in downtown Reykjavik
-there is a small art museum with a cafe after you finish hole 9 (yes there is a bathroom too)
-the park is very pretty and well maintained with trees, flowers and other plants

If you are looking for a challenge with long holes and challenging terrain, you will probably be disappointed.

This is a very short, very easy course in the town square of Reykjavik. It is 9 holes, with each hole being about 200-250 feet. Most of the holes are of the same length as Rutgers DGC in NJ (USA). I would think of it really as a practice course or an entertainment course, not professional grade. If you are at the competition level, you'll be able to play Klambratun with a putter for the most part, which is why it's so great to play if you're coming from overseas, are only bringing a few discs and just want to get a quick round in. It was great for me because I was visiting for a few days,and had a friend with me who hasn't played in years so it wasn't a huge commitment out of our day of sightseeing to play this course.

Easy to find. Easy flow. Good for beginners or those just visiting the city who want to get in a round of disc golf. Plenty of other locals around who can help out if you are visiting from another country. Park is well maintained.

A couple of holes have some technical shots, otherwise there is not a lot of variety if you are looking for a technical course. Other than tee numbers and an initial map, there is little signage, although it is fairly easy to find the next tee and see the next basket. I do not think there are bathrooms ("water closets") other than what is available at the museum located on the premises, which costs money to enter. There can be other park visitors in the way of some shots.

A very skilled local who was playing behind us told us that this course was not the best that Reykjavik had to offer. He advised taking a 15 minute car ride out of the city for one of the better and more technical courses. Unfortunately, I did not have that opportunity. There were quite a few other players there that day, telling me it would be fairly easy to get more information about local courses, and most speak English. I would advise playing this course if you are in the area because it is easy to get to, fairly typical, and you might not have another opportunity if this is the only time you plan to visit Iceland. It is fun to play and you won't be disappointed you did.

-It was easy to navigate and the course flowed
-Great baskets
-Easy location to find within the heart of Reykjavik (four blocks from my hostel)
-Fun locals, they let me borrow discs to play with them
-Good design for the limited space and trees in the park
^Mixture of shots
-Beautiful looking park
-I believe there were bathrooms but I'm not sure.
-Street lamps can light up some of the course... nice for when it's always dark

-Some holes were short and everything was par 3
-Some walking paths come into play and I can see errant shots heading in those directions
-Tee signs are really basic but the park has a great board out front

If you ever are in Reykjavik and have the time then I would play a fun short round. It's nothing stellar but it's cool knowing that disc golf is growing internationally. Also I believe they have leagues and doubles here. Might want to ask a local. Also, in the summer there is only a brief period of darkness... fun being able to play golf at 10 at night or 3 am after hitting a bar

Location is great and easy to find
Good course map at start
Easy to follow layout
You are playing disc golf in Iceland, what could be better!

Way to short and way to easy, more of a beginners track
Lots of people around as plays through public park
Not much shot variety

If you find yourself in Reykjavik, which I hope you do as it is a beautiful place, it's well worth it to get out and play. Nothing interesting or special about the course, but easy to get around in about 45 minutes and fun to have played in Iceland.
