Where is the closest national park to Aberystwyth?

Kicking off just 20 miles north of Aberystwyth is Snowdonia, a smorgasbord of jagged mountain peaks, expansive forests, emerald-green valleys, and sandy coastline that comprise one of the UK’s most popular national parks. Aberystwyth makes a good base for a foray into Snowdonia’s southern flanks, but within the park boundaries are no shortage of pitch-up places, such as those on the southern and northern slopes of Cadair Idris, Southern Snowdonia’s highest summit.
