Places I’ve been (and enjoyed):
Titanic Exhibition in Belfast
The Edinburgh festival
Tintagel
Stonehenge and Avebury (not everyone “gets” Stonehenge, and compares it unfavourably to other places, such as Macchu Picchu. But Stonehenge is much, much older and appears to have astronomical significance).
The National Gallery in London
Dennis Severs’ House in London
Glastonbury (not the festival, but the strange little town, including the Tor and Chalice Well Gardens)
The beautiful train ride along the South Coast from Exeter and over the Tamar bridge into Cornwall
Isle of Lewis and Harris. We stayed in Gearrannan Blackhouse Village, went kayaking and visited the standing stones at Callanish, amongst other things. I throughly recommend it.
Durdle Dor and Lulworth Cove, Dorset - gorgeous
Places still on my list:
St Kilda
Lundy
Burgh Island
The West Highland Railway
BAPS Shri Swaminarayan Mandir (a Hindu temple in London)
