Coasteering - Rhoscolyn


Use your climbing skills to traverse the cliffs, experience ‘wild’ swimming as you round headlands carried by the swell and test your nerve as you leap from the rocks into the deep – this is not a dry activity!

Rhoscolyn’s rocky shoreline is a fantastic place for your first experience of this unique challenge. With a stunning backdrop of the mountains of Snowdonia you can explore this beautiful craggy coast. There are offshore islets to swim and leap to, hidden coves and crevices to discover and deep cracks and fissures for the brave of heart.

Staffed by experienced instructors with excellent local knowledge and with low instructor to participant ratios, we’ll open up a new perspective for you as you explore this challenging environment.

The coasteering venues are a few minutes walk from our base at Outdoor Alternative. All activity sessions are tailored to the needs and abilities of the group. Our aim is to set challenging activities which take people into new environments giving them new skills and experiences, expanding their comfort zones and redefining their sense of what’s possible.
