Castlemartin Range Coast Path walk

Easy cliff top path following the Pembrokeshire Coast Path through a MOD range, past dramatic cliffs, stacks, arches, a secluded chapel and 2 remote beaches. Check access times!

Firing Range

You can only do this walk when the firing range is open - usually weekends, some evenings, and the summer.

See Castlemartin Range Firing Times Published mid-month for the month ahead. You need all 3 'open'. Reconfirm on the day if making a special journey - phone 01646 6622367 after 8:15 (recorded message).

Length 8 miles (12.9 km) out and back. Half that if you car shuttle. Less if you turn back early.
Toughness 2 /10 (higher if optionally visiting the beaches - 1 of which involves scrambling)
OS Map

This is an easy cliff top walk along a stunning and secluded stretch of the Pembrokeshire Coast Path, with dramtic cliffs, headlands, arches, stacks and hidden beaches. It passes the Green Bridge of Wales (a cliff arch), St Govan's Chapel (hidden in a gulley), and 2 remote beaches.

The walk is through the "Range East" part of the Castlemartin MOD Firing Range. Access is free, but only possible on certain days. You must check in advance!. You must stick to the sea side of the coast walk (marked by white painted stones). Route finding is easy - just follow the coast!

It is an out and back walk - don't worry, you'll be happy to do it twice! There are car parks at both ends if you want to shuttle. You can start from any of the 3 access points.

The cliff top path is fairly level, and away from the edge (i.e., not scary). There are 3 beaches you can visit, 1 easy, 1 medium, 1 a bit of a scramble. There are several short diversions to headlands.

Walk Options

You could make this a circular walk following the "Castlemartin Range Walk", an always open permissive path maintained by the army around the range boundary. Its waymarked with a tank symbol. Then, follow the Green Bridge / Stack Rocks access road to get back to your car. Far nicer to walk back along the coast! Note also that as the path is not a public footpath, the 'no bulls in the field' rules do not apply

Range West

Castlemartin has been a firing range since WW2. It is untouched by modern argriculture, so of great scientific interest for its flora and fauna, and is effectively a nature reserve. It is a major firing range, used about 40 weeks a year by NATO countries for training with live rounds from artillary, tanks, and anti-aircraft weapons.

The firing range is split into 2 parts, 'range east' and 'range west', by the 'stack rocks/green bridge' access road. This walk is in range east only, which is regularly open to the general public.

The "range west" coast path is, if anything more remote, and more spectacular, however this part of the firing range is never open to the general public (due to unexploded shells). Access is only possible on guided walks (about 1 a month) by either the National Park Authority or the local Ramblers group.

Note that there are differant arangements for anglers, cavers, climbers, and surfers, in recognised groups, who can get an annual permit after attending a safety briefing.

The "Coastal Cruiser" Bus 387/388, year round, about 2/day in each direction in summer, has a circular route: Pembroke Dock station - Bosherton (lily ponds) - Broad Havan (NT car park) - St Govan's car park - Green Bridge (Stack Rocks ) car park - past Range West - Angle - Pembroke Station. You could use this bus to walk 'one way'. Large groups should phone ahead to reserve space on 01437 764551.
