Open coastal headland with no admission charge; free for everyone.
No charge for anyone.
Two National Trust parking areas, both free and without marked bays. The bottom area is a grassy verge on the right a few yards after the cattle grid, with space for around 15 to 20 vehicles; the top area is on concrete ground at the end of the road with space for about 10 to 15 cars. The trail page lists the lower area as 'Free, limited parking at the foot of Mynydd Mawr'.
The map pin is the Trust's what3words car park address ///mammals.progress.lilac, which resolves to the top parking area beside the coastguard hut. Drivers pass the lower area on the way up; the circular walk starts from the lower area.
By road from Aberdaron village take the first right after entering the village and follow signs for Uwchmynydd; after the cattle grid you reach the bottom parking area, or continue up the concrete road to the top. Satnav LL53 8BY. Bus 8B from Pwllheli ends at Capel, Uwchmynydd, a 30 minute walk away.
Mynydd Mawr and Braich y Pwll form the westernmost tip of the Llŷn Peninsula beyond Aberdaron, the best mainland viewpoint for Ynys Enlli (Bardsey Island) across the treacherous tides of Bardsey Sound. A concrete road climbs to a former coastguard hut on the summit, with views of Llŷn, Eryri and, on clear days, the Preseli hills and Wicklow in Ireland. In the Second World War the hill was a signal station housing around 70 RAF personnel. Choughs dive and swoop along the cliffs, the headland of Braich y Pwll is the only place in mainland Britain where the spotted rock rose grows, flowering between June and August, and rare golden hair lichen clings to the rocks. Reviewers describe 360-degree panoramas and a fine walk down to the point. Livestock graze here, so dogs must be kept on leads at all times. The two-mile circular trail starts from the lower parking area and follows the Wales Coast Path before turning inland beside a brook.
Open coastal headland from dawn to dusk every day; the Trust's calendar shows every day to 31 December 2026 fully open.
No toilets or other facilities. A concrete road leads from the bottom of the hill to the top car park with views from both points; from the top the terrain is uneven with steps and rocky crags beside the coastguard hut.
Livestock graze the headland, so dogs must be kept on leads at all times.

The national coast path crosses the headland below the summit and is signposted at stages 3 and 4 of the Trust's circular walk. Dog rules on the wider path were not researched.
