"My wife and I had the pleasure of taking this tour with Mark. We thoroughly enjoyed ourselves. Mark is friendly, warm and well spoken and has a wide range of information at his fingertips, all dispensed with a warm sense of humor. I would recommend this tour to everyone!!!

"We signed up for this tour to Keukenhof and weren't disappointed. We were in a group of just eight people and our guide Rory, was charming and funny. We had three full hours in the Keukenhof gardens. What a delight that was! After that, Rory drove us through back roads and we stopped off at some flower fields for some photos au naturel, and then we went to a real Dutch pancake house. It was fun and kitsch, the pancakes were great and we had a quick walk in a nearby nature reserve where we saw some deer... And then it was onwards to Haarlem where we visited a windmill... All in all a wonderful day out."

"Lee took us around Amsterdam on the walking tour which was great. She’s definitely knowledgeable, knows her way around the town, gave us great recommendations and made things as comfortable as possible for us. We enjoyed the tour and definitely worth the money."

"After all my travels across Europe, I have become very fond of walking tours. This was hands down the best tour! Mark's tour was addictive! His content was fascinating, and his personality made everything so much fun! I would HIGHLY RECOMMEND doing this on your first day, to better your understanding of all things in Amsterdam!"

"Absolutely loved this tour with Mark! He is a very thorough and considerate guide. I took a picture of something on the tour and he emailed me a picture of that particular building from years ago later that day. This is a great way to learn about Amsterdam and The Netherlands and I highly recommend this small group tour!"

"Bottom line -- if you are going to Amsterdam, you can't get a better introduction to the city than the 3-hour small group walking tour offered by Mark of That Dam Guide. He provides a thorough but nicely paced overview of the city that can serve as the perfect starting point to your Amsterdam vacation. Knowledgeable, friendly, funny -- Mark had it all and we couldn't have been happier with the experience."

"We did both the City Walking tour with Rob and the Red Light District tour with Lee. Both tours were extremely informative. We find that walking tours provide extra insight and information that you wouldn’t find in guidebooks, with the personal touch of engaging and friendly guides. Thoroughly recommend both tours!
