Glas Tulaichean is an interesting and complex Munro. It is bitten into from all directions by corries resulting in a fine array of summit ridges. The main summit ridge runs SW - NE with the summit sitting in the SW corner of it. From here there ridges branch off W, S and SE. To the east of the summit the ridges are defined by the two deep biting corries Glas Choire Mhor and Glas Choire Beag giving craggy slopes on the ridges that run round the rim of them.
The usual route of ascent is up the SW ridge where a well defined path leads to the summit from Glen Lochsie.
Glas Tulaichean is normally climbed in conjunction with its neighbouring Munro Carn an Righ which is connected via a low col to Glas Tulaichean's NW ridge running down the left hand edge of the coire Glas Choire Bheag.
Glas Tulaichean is a great hill that is well hidden away. It is only really visible from the surrounding Munros in the area.
Access is normally from The Spittal of Glenshee on the A93 to the SE. Itís a long walk in with Glas Tulaichean logically being climbed first before tackling Carn an Righ via the above mentioned col and descending back down to the same col.
