At present I do not have any archaeological holidays planned for 2020.
I will be guiding walking holidays for HF Holidays in Scilly and we will visit many of the archaeological sites on these. There will be nine 6 night holidays, based at the Bell Rock Hotel on St Mary's, between April and September 2020. We spend a full day walking on each of the inhabited islands: St Mary's, Tresco (with an opportunity to visit the Abbey Garden), St Agnes and Gugh, St Martin's and Bryher.
Full details are on HF Holidays' website.
