Salmelanlampi is a compact bouldering crag with several aesthetic boulders in a beautiful forest. Some of the proudest lines might be a bit high for some climbers but for those who enjoy it you're in for a treat. Stone quality is good, mostly gneiss.
Access is only a few minutes from the parking spots. Logging trucks use the road often so please keep this in mind when parking.
There is a summer cottage near the main bouldering sector. So keep the area clean, brush your tickmarks after you leave and keep noise to a minimum.
trivia: If driving from the south through Vääksy there is a wonderful restaurant called Kanavan Kunkku which is a perfect place to stop on the way. Sysmä on myös iha vieressä.
