Gren Tours is ‘Blue Badge’ qualified tourist guide Glen Portch. Glen was born just outside London and has lived, worked and played in and around London for most of his life. However, he realised how little he knew about his native city and country when friends, visiting from overseas, asked questions. Eager not to embarrass himself again, he took the Institute of Tourist Guiding‘s “Blue Badge Guide” course and he gained his qualification in 2004.
Glen offers private tours of London and Great Britain for individuals, small or large groups. He has experience of guiding families, groups of school children, A (and B!) – list celebrities and the presidents of multi-national companies. The emphasis is on fun, tailor-made tours and this website is designed to give you some ideas. Once you have browsed this site and are interested in booking a tour or would like more information, please contact Glen via the contact page.

As a huge music fan Gren Tours rock 'n roll tour of London seemed right up my street! It turned out to be a great experience, with lots of stories of recording, gigging & musical excess! This is must for pop culture fans in the capital! With a particular personal interest in Bowie & Bolan I came away very happy indeed! Cheers Glen! 🎶

Glen Portsch rocks! His rock and roll London walking tour complete with pictures and videos from yesteryear brought us all down Memory Lane and singing along to the late great classics. And his stories behind the great legends and the places they visited had us all enthralled. A very pleasant two hours gentle stroll through surprisingly peaceful, picturesque backstreets of London brought those heady days alive. A really groovy experience!

Highly-recommended Rock 'n' Roll Tour in Central London Glen gave us a great Rock ’n’roll tour around Soho & Piccadilly in the centre of London. We started with a handy historical overview of British Rock ’n’ roll, then went to see the actual sites of some of the most famous, former recording studios, cafes, clubs and gigs… Glen brought it all to life with great stories and insights, as well as his own personal passion and deep knowledge of the subject. Couldn’t ask for more - highly recommended! Frances Linzee Gordon

Highly-Recommended English Wine Tour Glen gave us a great tour of two of England’s most famous vineyards, including an excellent overview of wine-making in England on the journey on the way. We had two great site visits, which included a guided walk around the beautiful, Kentish vineyards, a tour of a winery & its production process, and two very informative and enjoyable, guided tastings of the different wines themselves. Glen was a knowledgeable, efficient, friendly and very accommodating guide who took incredible care of us and ensured we were very well looked after throughout, including even providing us with notes after our visit. Highly recommended!

Excellent autumn day in the beautiful vineyards of Kent, Super full day out with Glen. He guided us down from London into Kent. We learnt about the growing wine industry in the UK and the many vineyards in the south. We visited two very different vineyards. Chapel Down - largest in England and the boutique Woodchurch. Great contrast. Lunch was in beautiful Tenterden nearby. Nothing was too much trouble for Glen. Big thanks!
