Birding in Roslin Glen
Roslin Glen is one of the most attractive woodlands in the Lothians. As part of the
North Esk valley, it comprises mature woodland surrounding a fast-flowing, small
river. It contains some of the most important areas of mature oakwood in the
region. Roslin Glen and the surrounding countryside are host to a wide variety of
birds, wildflowers and mammals. Key birds found in this area are jay, nuthatch,
green woodpecker and kingfisher. Roslin Glen is worth a visit any time of the year
but springtime is special because the wood is carpeted with bluebells and is alive
with bird song.
Roslin Glen forms part of the North Esk Valley and is located approximately 8
miles south of Edinburgh. The source of the North Esk river is the North Esk
Reservoir in the Pentland Hills.  It flows through several Midlothian towns –
Penicuik, Auchendinny, Roslin, Polton, Lasswade and Eskbank – and also
through some beautiful Midlothian countryside before its confluence with the
South Esk at Dalkeith Country Park. From there the Esk flows north to  
Musselburgh, another prime Lothian birding location.
Rosslyn Castle and Rosslyn
Chapel are of historic interest and well worth visiting.

Getting There and Getting Around
By car:
From the A720 (Edinburgh City Bypass) take the Straiton
exit and follow signs to Roslin. To access from the south
take the A7 to Bonnyrigg then the A6094 towards
Howgate. There is a small car park at the turning into the
B7003.
By bus
From Edinburgh Roslin is served by Lothian Buses
15/15A. Rosewell is served by Lothian buses 31 and 49.
Habitat
Roslin Glen comprises mixed woodland, with good
numbers of mature oak, birch,  and ancient Scots pine. In
places the banks of the glen are steep, particularly in the
section downriver of Roslin. Wild garlic and bluebells
carpet the glen in springtime, and the area is rich in
wildflowers. There are cliffs both at
Hawthornden Castle
and upriver from Roslin at Powdermills.

Bounding the river valley itself are expanses of arable
farmland and grassland. The Hewan Bog provides some
marshy habitat between Roslin and the neighbouring
village downriver, Polton. The river itself descends
quickly, and there are many rapids as well as sections of
slow water. The river loop by
Rosslyn Castle forms a
small gorge and the area bounded by this is open and
scrubby. Gardener’s Brae is a south facing grassy /
scrubby slope between the castle and the chapel.
Birds
The mature woodland of Roslin Glen hosts all of the common Scottish woodland
birds such as tits, finches and thrushes. Great spotted woodpecker are very
common, and green woodpecker are now quite often heard, if not seen, between
Roslin and Polton at the wood margins. Jays have started to colonise the oak
woodland and can be found in all areas but the Hawthornden, Hewan Bog / Wood
and Maiden Castle sections are most favourable. Nuthatch were first noted to
have bred in Roslin Glen in 2005 and several pairs now inhabit the glen in the
woods adjacent to Rosebank and Hawthornden. The range is expanding annually.
Warblers are abundant, especially around Rosslyn Castle, Gardener’s Brae,
and along the margins of the Penicuik-Dalkeith walkway and the Roslin-Polton
walkway. Willow warbler, chiffchaff, whitethroat, goldcrest and blackcap are
common and garden warbler are seen every year at Gardener’s Brae. Wood
warbler have formerly been known to breed in Roslin Glen and still breed
elsewhere in the North Esk Valley so it’s worth looking out for them in the spring.
Spotted flycatchers may be seen along the wood margins; pied flycatchers were
at one time semi-regular breeders in the Scottish Wildlife Trust section. Tree
sparrows are seen regularly near the chapel and along the Roslin-Polton
walkway.
On the river itself dipper are common, and kingfisher can sometimes be seen
(they are seen regularly at Auchendinny, which can be reached via the
Penicuik-Dalkeith walkway). Grey heron, grey wagtail, mallard, moorhen and
occasionally goosander are also present.

Raptors are usually visible at some point during a walk in the area. Buzzard,
kestrel and sparrowhawk are often seen. Ravens, peregrine and goshawk are
occasionally sighted. Tawny owls are common, and barn owls are occasionally
seen hunting over the farmland bounding the glen. Around the margins of the
woodland birds of open ground occur, such as swallows, house martins,
yellowhammer, skylark and meadow pipit.
In winter look out for fieldfare and redwing, and occasionally waxwings. Siskins
may be seen feeding on birches and conifers.

Esk Valley Trust website
(information about the Esk Valleys)
Roslin Glen can be accessed from several places:

Roslin
Park on the Main Street, Penicuik Road or Manse Road.
There are three options for exploring from here: (i) walk
along Chapel Loan to access the paths near Rosslyn
Chapel and Castle; (ii) walk along Manse Road to access
the Roslin-Polton Walkway - this provides more direct
access to the Hewan Wood and Hewan Bog sections; (iii)
walk north along Roslin Main Street until you are almost
out of the village and join the path along the Kill Burn, a
triburaty of the North Esk.

Roslin Glen Country Park car park
This is accessed via the B7003 from Roslin (the road is
closed from the south [Rosewell] side). Paths run from
here across the river to the castle / chapel areas, or you
can walk a short distance back along the B7003 to the
entrance to the Powdermills section of the glen.

Penicuik-Dalkeith walkway
. This can be accessed at either end by bicycle, and there
is a small car park at the Rosewell end of the B7003. At
present this has to be accessed via the A6094
Bonnyrigg-Howgate road as the B7003 itself is closed
because of a landslip. Walking west towards Penicuik,
several paths branch off this walkway into the woods and
about a mile from the car park a  steep set of steps leads
down to the Powdermills section.
