As of spring 2025, the Bolt Committee has begun renovation work and has also developed the cliff with some new, funky sport routes. Runsa is now considerably more versatile and clearly more interesting even for those who only climb sport routes. The topo pictures and descriptions are currently somewhat temporary. New and better topos are expected to be available in November 2025.
In a beautiful and quiet natural area next to Lake Mälaren, 5 km northeast of Upplands Väsby, lies this crag. From the top of the ancient castle next to the crag, you have a mile-wide view over the water and away towards Märsta. This crag is 75 meters long, and the routes range from 10 to 20 meters high. The rock is mostly solid and fine gneiss/granite.
The main attraction is a clean overhanging flat face, far right on sector Huvudväggen. Here you will find a few crack lines and some bolted face sections, mostly offering quite demanding traditional/mixed climbing. Be prepared to use a lot of energy when placing the gear itself.
The route Vampyren is considered a real gem and a classic in Stockholm, and it's a must-do if you are into traditional climbing. It's easy to rig a top-rope if you want to try some of the more demanding classics, which is good, as the majority of climbers most likely would top-rope these routes before they lead them. Vampyren, however, is considered to be alright protected, but still demanding as it is overhanging and pumpy.
Follow the path back around the crag to get to the top.
The Bolt Committee has begun renovation work. Information about which routes are involved can be found under each climbing route.
The left part of the main wall, which is somewhat difficult to overlook, is divided by ledges and corners of varying sizes. However, if you give it some time and inspect it, you will find quite acceptable shorter sections and routes. Here, you will also find the newly bolted sport routes (2025). Some of the scattered bolts have been replaced, and several anchors have been fitted (in 2013 and 2025).
Flugväggen:
40 meters from the main wall is Flugväggen, which is an eight to ten-meter low-angle crag with a couple of nice routes that give more climbing than you might think. Unfortunately, the moss tends to grow quite quickly in this sector, although the central part usually remains in better shape. Bring a brush. Here are also a couple of unreported bolted routes.
Skeppsättningen:
Straight into the forest at the “stone ship” is a 30-meter wide and 6-9 meter high overhanging little nice crag. It has two main walls, the left of which is the steepest (100 °) but also the lowest. The right part is quite shady. The four routes are well worth doing and have a lot of climbing for the meters. Many of the routes have their crux at the top, which makes them less suitable as boulders. There are still some possibilities for new routes.
Bring a brush, as it can be mossy.
Environment:
Southwest facing. Mostly open, but some shade at the base here and there. Great in spring and autumn, but hot in summer.
