Any other favorites? Maybe even local trails we haven't heard of.

I didn't respond to this post at first because I've done many really good hikes, but I don't know the names of most of them. Some were in Olympic NP, Mt Ranier, Yosemite, Sequoia, Banff and Jasper, Rocky Mountain NP. My favorite so far in RMNP was the walk from Bear Lake to Cub lake via Odessa Lake.

I just walked segments 9-11 of the Colorado Trail with family members in July, about 46 miles near Leadville over the course of 6 days. The trail from Tennessee Pass to Turquoise Lake was incredible, especially around Porcupine Lakes.

In tems of local trails, in and around Durango, CO, there are several classic hikes. I'm not including "difficult" (according to the Forest Service) hikes, because I don't tend to do them. Here are some I like:

Easy: (Most of these are approached by rough rock roads; only the third requires 4WD.)

Spud Lake hike - starts from Old Lime Creek road, which is a great drive in its own right, north of Durango.

Big Al trail near Mancos is handicapped accessible (I think) - just a nice walk through aspen to a great viewpoint. This makes the list because I was able to take elderly, arthritic flatlanders on it.

The walk from the parking area near Kennebec Pass to Taylor Lake and beyond - goes through impressive fields of wildflowers with peaks all around. Lots of great picnic spots.

The walk around the Big Meadows Reservoir just east of Wolf Creek Pass.

Moderate:

Much of the Colorado Trail. The stretch between Molas and Kennebec Passes is particularly spectacular.

The hike from the Bandora Mine to the Animas-Dolores divide in the ineral Creek area just northwest of Silverton. Looks down on Lake Hope and Trout Lake.

Animas City Mountain on the edge of Durango is good because you get great views north, up the Animas valley, and views south to Durango.

Haven't had the opportunity to do much hiking out west, but we enjoy the Whiteoak Canyon trail in Shenandoah Nat'l Park.

I live in the Northwest and there are so many great hikes and climbs
Mt. Rainier/Mt. Adams/Mt. St. Helens
and all the hikes and trails around these great mtns.

Specific climbs
Granite Peak
Mt. Dickerman
Cutthroat Pass
Twisp River Pass
Chelan Lakeshore Trail
War Creek Pass to Stehekin
I could go on and on but then that would be really boring!

Good trails are never boring. Exhilerating--challenging--peaceful--meditative--tiring--but never boring!

They don't all "have" to be nature hikes, right?
1. Lake Quinault Rain Forest, WA
2. Ruby Beach, WA
3. Black Forest, CO
4. Most of the trails in Sedona, AZ
5. Walking from downtown San Francisco so far out that we could see the entire skyline before we realized how far we'd gone (it was our first visit)
6. Perdenales Falls, TX
7. The beach in Seagrove, FL (before Seaside developers "found" the area)
8. Boston
9. Paris - all around town

Wintertraveler- I liked your response- thinking outside the box ;0)
I like nature hikes but also just trekking through an interesting city. I know they offer "walking tours" in Europe. I gather they are organized tours where the participants walk from one place to the next (not just a city walking tour). Has anyone ever done this?

I also enjoy hiking as well as fine dining. I need the former to burn the calories of the latter! For those with bad knees etc. I think it is still of value to try a scenic trip with a small boat ride/or float plan trip to get your self reinspired about the beauties nature has to offer.

Standing at the top of Nevada falls after hiking 3-hours uphill and past Vernal Falls (Yosemite) was an awesome experience even if the last 20 minutes was spent wading through snow with wet socks.

Denali Park and anywhere in Alaska is also a very refreshing experince. Trails in Petersburg are flat and made of wood for easy tranquil hikes.

Don't remember all the names - but every hike I've done in the White Mountains of New Hampshire has been breathtaking.

Also agree - any in Sedona.

For a flat but extremely scenic 3 mile hike - Cliff Walk in Newport, RI.

The 5 1/2 miles sea wall around Stanley Park in Vancouver.

I love to hike, love to eat, love to do almost anything to do with traveling. What's not to love. Our most recent hike was on the Mendenhall Glacier in Alaska. Awesome.

I enjoy big city vacations as well as wilderness ones.New Orleans or Yosemite, they both sound great right now. ........My favorite hike is the Mt. Tallac trail at Lake Tahoe.Unbelievable views! But don't go there, it's already too crowded.Just kidding
