Scotland’s Highlands Eco Tour

Aigas Field Center

Led by Sally O’Byrne
July 6, 2024 – July 13, 2024

Spend 8 days at the Aigas Field Center in the Scottish Highlands for a guided holiday featuring wildlife, birding, history, botany, and scenery. 

Aigas is Scotland’s premier field study center, dedicated to nature conservation and environmental education.  Aigas is a thriving nature reserve; an example of responsible ecotourism and restoration ecology; and a scenic place to experience and learn about Highlands wildlife and cultural heritage. 

On this Delaware Nature Society eco tour, you will be able to enjoy the grounds of the nature reserve, learn about the reintroduction of European Beaver, experience nearby ancient Caledonian pine forest, see many species of birds including Golden Eagles, European Dipper, Crossbills, Red Deer, and British Primitive Goats.

Visit Neolithic Clava Cairns (an ancient burial site), Culloden Battlefield, Cawdor Castle and Gardens, shores of the Highlands west coast, the shores of Beauly Firth to spot otters, and the River Beauly.  Birds, mammals, wildflowers, and scenery will be infused with each field trip. 

Finally, a visit to The Black Isle will finish off the week.  This mix of pebble shores, cliffs, agricultural lands intermixed with native woodland and old hedgerows will afford opportunities to look for many species of plants (some rare), shorebirds and many other bird species.

Overnight stay and meals will be provided at the Aigas Field Centre during the trip.  No single supplements are charged, and accommodations are in cozy timber lodges nestled among the trees.  Breakfast and dinner is served on-site, and packed lunches are provided for field trips.

Travel to Inverness Scotland is not included and options will be discussed with you after registration.
