Megalithic Preseli Tour in mid September – places remain available!

Organised by VIP Wales and with Robin Heath as Tour Guide

Sunday 15th – Tuesday 17th September 2019

Like the previous course , this course is based around the Cnapan Hotel and Restaurant in Newport, Pembs.

However, there are also several places for local people or those that would prefer to take an alternative option – bring a camper van or caravan, tent or book into a YHA Hostel.

VIP Wales have put together a course to run on the above dates and have asked me to provide them a suggested itinerary. Enclosed below, in modular form, this tour provides alternatives in the event of poor weather. At this stage it is preliminary but gives a good indication of the extent and content of the Tour’s intent.

September is a great time to visit the Preseli region and the weekend of the 15-17th embraces the Full Moon period. The hectic holiday period during August has long since subsided, while the weather is often sunny and warm with gin clear skies and there is still enough daylight to be out and about until 7:30 or even 8pm. The longer shadows during the day make visiting megalithic sites even more atmospheric.

For this second Megalithic tour, we introduce the role of Castell Mawr as the centre of a ‘Preseli Wheel’, and the undoubted significance of Gors Fawr as the principal and more or less complete surviving stone circle.

Each of the following ‘modules’ may be integrated into a bespoke tour by prior consultation with the client(s). Once this is defined, then the flexibility will centre around weather conditions and, importantly in Preseli, access to toilet facilities, which are limited, although Castell Henllys is a good venue for WC, books, prehistoric vibes and a coffee in bad weather!

Please note that none of the above is set in stone, unlike the actual megaliths, blue or otherwise, so it will be necessary to await the final form of this proposed programme in due course.
