ThingsToDoHolyhead Mountain as the main outing →
A dedicated hill walk for a suitably prepared group in good conditions.
A demanding walk to ancient summit remains / NEAR HOLYHEAD
Holyhead Mountain and Caer y Twr
Climb only in suitable conditions to see the hillfort and later watchtower remains above Holyhead. The interest lies in the exposed position and surviving walls as well as the views. Treat it as a proper hill walk with a planned return, not a quick extension to a museum visit.
Before you go
Cadw grades the terrain strenuous. Choose this only if the whole group is comfortable with rough, steep ground, navigation and the weather on the day.
The practical details
- Where to find it
- Holyhead Mountain, Holy Island, west of Holyhead
Directions and arrival information ↗ - Tickets and booking
- Free monument access during reasonable daylight hours, subject to conditions. Car parks at the mountain’s base may charge. No staffed visitor service is implied at the summit.
- Access and getting around
- Steep and uneven mountain terrain makes the summit unsuitable for wheelchairs or buggies. Use an appropriate walking map and a route matching your ability, with time and energy for the descent.
Official access information ↗ - Visiting with children
- Suitable only for children already comfortable with this kind of hill walk and close supervision. The country park offers a less demanding alternative; a summit is never necessary to complete the day.
