Best 5 day hike…small emphasis on fishing…within 5 hours of Denver

How many miles are you thinking? One person's 5 day trip is 125+ miles, another person's is a quarter of that.

20-40

Thanks for reply!

I'd look into the Indian Peaks Wilderness, which is only about one hour from Denver. Permits are required in the summer. The James Peak Wilderness is just south of IPW and does not require permits in the summer. I'm not sure about the fishing.

Mags has a good write-up on a loop in the IPW here:

There is also the Four Pass Loop, which is near Aspen (about 3.5 hours from Denver). It's something like 26 miles, loops around the Maroon Bells, and crosses four high passes.

This should get you started…

Indian Peaks sounds great…I'll check out the permit. Loop near Aspen looks pretty cool too. Thanks again for feedback!

I would leave the dog at home.

Thanks for feedback…

+1 on leaving the dog at home. The loop is pretty serious terrain for such a small animal. And within the wilderness area, you'd have to keep it on leash. I love hiking with my 70 lb dog, but in IPW he's a liability. I take these trips to relax, but keeping him on a 6 ft leash means I spend more time watching the trail than appreciating my surroundings.

Goose creek trail has an option to do a loop. Good fishing, lots to do, incredible scenery. A little over 20 miles. Close to denver too

We brought our 6 lb Italian Greyhound. She did fabulously. (But actually comes for every trip and never had a problem).

I second this. Getting to the trailhead is interesting, but doable in just about any vehicle. I had a great time in the area, gorgeous. Just be aware that due to the drought, water levels are pretty low and the "regular" water sources may not be there. Lost Creek was still going pretty well, but a lot of the tributaries were dried up/trickling when I went the end of June.

Take a look, several people fishing at Crater Lake.
