Brandon, thanks for the article and discussion. I prefer to play when and where walking is allowed, except when a mandatory cart invitation is too good to pass up. I was schlepping until age 60 when I relented to a push cart (timely Father's Day gift). Totally agree with you - green to tee proximity and reveals for sure make for an extra special hike!
A great resource is The Walking Golfer Society - https://thewalkinggolfer.com/

I lived in Austin a few years and Lions was my home course, and I hope SaveMuni survives - Jimmy Clay, Roy Kizer and Blue Bonnet Hill are very fun walks as well.
Living in Denver, we are good-walk spoiled with many choices - some of my favorites are Riverdale, Meadow Hills, Green Valley Ranch, Coal Creek, Indian Peaks, Raccoon Creek, and Fox Hollow.

Memorable public course golf walks for me are too many to include them all. Some that stand out in my brain: Montauk State Park NY; Duke University, NC; Caledonia, SC; The Bandit, New Braunfels, TX; Papago, AZ; Singing Hills, CA; OGA, Pumpkin Ridge, OR; Shuksan, WA; Bemidji Country Club and Chaska Town Course, MN; Brown Deer State Park, WI; Black Lake, MI; Glen Mills, PA; Neshanic Valley, NJ.
Being retired military, I also have a penchant for military courses, too many going extinct.

Nothing beats finishing up a good round, hiking it into the 19th hole, at twilight on a June evening!

Golf is always better walking. I will try and walk even on trips were cart is included, in Wisconsin two great courses to walk is whistling straights with great views of the lake. Sand Valley’s Mamonth Dunes is also a great walking course. Not really any great scenery, but just nice gentle rolling hills that hide holes from each other and super easy to walk. Always love to walk my home course Cedar Creek with great views of Mississippi valley.

Your colleague Tim may agree that The Fenwick Golf Course (Old Saybrook, CT) is a great nine hole walk. Not many hills to climb (if any?) and you're treated to great waterfront scenery as well as a jaunt through a fantastic, classic New England neighborhood. Instagram has a few photos (link below) and this reminds me that I owe Golf Advisor a review of this place!

If you get a chance to get to South Africa head to Gary Player CC in Sun City as it runs along Pilansberg National Park and you never know what you are going to see. Its a good walk and the course will challenge you.

One of the most enjoyable rounds I ever played was on a little known course near Vancouver, BC called Sandpiper (yes, another Sandpiper), in Harrison Mills. I played it on the last great sunny warm day in mid-October, finishing in shirt-sleeves as the sun went down. A shorter course, but mostly through the woods with some finishing holes along the river. What really made it special that day were the small streams that run throughout the course were filled with salmon swimming up to spawn, some in only inches of water. As a result, it hosted probably 100's of eagles in the area, feasting on the easy catches. Add a few deer to the mix and can it get any better? Yes. When teeing off on one hole, an eagle was perched on a branch about 40 feet above my head. Just as I was about to swing, it swooped down right in front of me, its 7 foot wing span whooshing up the fairway between the trees.
Book a round there (and a stay at the accompanying Rowena Inn and cabins) for an early to mid-October date. You won't regret it.

My favourite walk, up to the green, was and hopefully can do again, is the 18th at Radium Hot Springs Resort, in Radiaum Hot Springs British Columbia CANADA. The green reminds me of 18, at Augusta with the Sunday backstop, just behind the pin. Rarely, was the pin anywhere else, when I played. I loved admiring my approach, as it hit, just beyond the pin and drew back to the pin. My shots never went into the hole, but just the excitement of the action on the ball, doing exactly what I had hoped for, was priceless,

Highland is a great course. I haven’t played it in years and I know it occasionally has maintenance issues. It is a LONG walk and the one you describe at the 12th hole is a good half mile from green to tee, but— you know, it is a quite lovely walk along the river. Scotland has many good 9 holers. My favourite is Tarland, in Aberdeenshire , an Old Tom Morris creation which is a nice walk with brutal successive holes at 4, especially 5 and 6. I also love Rosehearty which I played for the first time last year. Golf as it used to be. Clubhouse was closed, no trolleys, you paid in the pub across the road, wind was up, blind holes, etc, what fun all for £15.00. And Scarista! ——I could go on.

Thanks Brandon for the interesting article of walking golf courses. I would like to note that Otter Creek (Trent Jones Sr. 18 and Jones' son Reese did 9 more) in Columbus, Indiana, is one of my favorites for walking (has relatively close green to tee walks). It is a wonderful challenging layout. Although, after Cummins Engine donated the course to the city maintenance has been something to be desired, unfortunately.

I agree with Tim on Fort Myers Country Club. A classic Donald Ross course that opened in 1917. Much more fun to walk than ride. I also enjoy walking Maple Leaf Golf Course in Linwood, Michigan. A 1960’s vintage family-owned and operated course that offers 3 different 9-hole experiences. A beautiful walk during the fall colours. And the course I consider my home course, Burlington Springs Golf and Country Club in Burlington, Ontario, Canada. Another great family- owned course that is a great walk in all seasons

Sandpiper Golf Course in Goleta, CA is a good as it gets.
