This course is in its 20th year. It comprises a number of excursions to bring to life Devon’s fascinating geology – and how this relates to the equally rich natural history. Using our giant 12 foot collage, the fossil seascapes of the Devonian period (+/- 375 million years) will be explained in detail in context of changing continents and climate.

Plant life will also feature strongly – their uses, folklore and more, made interesting and easy to understand, often with humour! Over 400 species have been seen – special attention to identification through families is the order of the day down to basic species level but no further.

Our geology excursions will take us into the amazing world of rocky shore marine biology – again detail made plain will be the order of the day. The course is suitable for those wishing to learn basic geological principles – teachers will find it very useful.

Butterflies, moths (we run a trap) bats and industrial archaeology will also feature.

We cover adaptive morphology as the course includes both past and present marine biology.

The course will be suitable for beginners and the more knowledgeable geologist and naturalist. Lots of detail will be made plain and interested children of 14+ years are welcome with an accompanying adult.

The course is very full-on and there is a fair amount of travel but the locations make it well worth it. Often we swing from one topic to another without moving when on the headlands – they are that good.  This is not a birders course, but we have a list all the same – over 60!

Some locations might be difficult for the less mobile to get to the last few metres – but there will always be something interesting nearby. There are locations where a good head for heights comes in handy – the course is based on headlands! In case of bad weather or tides we can alter the itinerary to visit sheltered nearby locations for short periods.

“Over the last 19 years I have always looked forward to running this course and have had little reason to change anything. We have had a wide range of people – some have been experts themselves, others beginners; teachers, but all have carried an enthusiasm and willingness to share knowledge. Camaraderie and humour has been wonderful each year. There are two very friendly bearded collies on this course – most participants have found them to add to their enjoyment and on the last course some were sad to say goodbye!” – Martin Summers, course tutor

The tutor is more than happy to discuss this varied, detailed and diverse course over the phone or by email with potential participants. Please feel free to contact Martin on: 01822 841176 or email him on [email protected] to discuss any aspect of the course.

Example Timetable

Weather conditions and other factors may alter the programme - but this outline gives a good idea of what is in store.


Introduction to the course after supper, followed by a trip to Hallsands to view the Lighthouse and ruined village at dusk from the viewing platform.


Brixham. St Mary’s Bay and Berry Head.
A day looking for and learning how to recognise fossils using our giant collage. Their mode of life is made apparent using our Devonian seascape. We will visit Berry Head to see spectacular cliffs and views and enjoy the unusual wild flowers, including orchids, identifying them as we walk.  Fossiling on the River Dart is another possibility.


Dartmoor Walk - Haytor and Houndtor.
Using historical sites and trails we study the geology and natural history. A varied day – quarry pond, tramlines to follow, moorland and wooded valleys and maybe climb Houndtor.  This day contrasts with the coastal walks and puts the geological scenery and history in context. The pond and medieval village are memorable and strike up the human historical impact of Dartmoor.


Hopes Nose, Torquay.
The chance to walk and touch the fossilised sea floors/reefs on a wave-cut platform dating from the time of great sea level changes tens and hundreds of thousands of years ago.  Interesting “step faulting” and very clear evidence of volcanism (ash layers) folding and thrusting.  Best example of a raised beach in the South West, showing fossil shells (200,000+/- years old).  Devonian fossils 375 million years old, gold, marine biology, stromatoporoid “buns”, and see the botany on the way down, and back, and all in one day! If time allows the marine biology is well worth looking at - an unusual sea slug can be found here. Humming Bird hawk moths are also to be seen here.


Start Point, Peartree Point and Mattiscombe Sands.
A general walk explaining the geology (metamorphic rocks different to previously encountered) and geomorphology (wave-cut platforms, sea level changes, marine landforms), botany, butterflies and marine biology will feature strongly.  Seals can usually be seen at Peartree Point, which shows rare local evidence of “ice action” as well as underwater arches. We will visit the Lighthouse for spectacular views - the butterflies here have been prolific.


Saltern Cove, Paignton.
A coastal walk will show some of the most outstanding Devonian and Permian geology nationally, including a classic unconformity representing an ancient land surface.  See the burrows of some long extinct species, sea floors crammed with fossil corals, imagine the volcanism associated with the repeated beds of ash and unravel the story of rising sea levels in the Devonian period using our giant collage.


Gorah Rocks, Prawle Point.
A marine ramble linking the sea life of today with previous fossils seen.  Spectacular scenery, metamorphic geology, sea level changes and head deposits - all will be explained!  There will be excellent botany, insect life, and a good beach combing strandline to explore. In the evening there will be a summary of the week.


Depart after breakfast.
