New to the forum here as I am looking for (probably a lot of) advice.
Just to get started, since last spring, I've been tentatively planning what I've taken to calling the "Great Western Road Trip", which involves 6 weeks and a good mix of National Park camping/hiking and hotel stays in select cities. However, the longest road trip I've actually undertaken was 3 days (a couple of times), and that was generally only for actual transport, rather than recreation, and also with a friend/co-pilot, rather than solo, like the majority of this trip. I'm hoping that some more experienced road trippers can temper my expectations and make some helpful suggestions. I've been using the Roadtrippers app to plan the stops at a high level, but every little bit helps.
Just a quick note: My general National Park plan is arrive on day 0, do a longer/challenging hike on day 1, smaller hike/relax/rest/tour/etc. on day 2, then leave on day 3 (with some exceptions).
First, the planned trip (with tentative dates and mileage estimated by the app):
I live in San Diego, so that's both the start and end point.
Stop 1 (6/16, 346mi) - Hoover Dam. Not staying, but mostly just for touring. I was planning 2-3 hours for touring and photography (a big driver for the road trip).
Stop 2 (6/16-6/19, 193mi) - Zion NP. Standard NP plan.
Stop 3 (6/19-6/22, 121mi) - Grand Canyon NP (North Rim, probably). Standard NP Plan.
Stop 4 (6/22, 124mi) - Antelope Canyon. Just touring, again. Planning on another 2-3 hours.
Stop 5 (6/22-23, 122mi) - Monument Valley. Just overnight, really.
Stop 6 (6/23-6/26, 152mi) - Arches NP. Standard NP Plan.
Stop 7 (6/26-6/29, 511mi) - Grand Teton NP. Standard NP Plan.
Stop 8 (6/29-7/3, 135mi) - Yellowstone NP. Extra day.
Stop 9 (7/3, 467mi) - Devil's Tower. Touring
Stop 10 (7/3, 74mi) - Deadwood, SD. Overnight stay.
Stop 11 (7/4, 49mi) - Mount Rushmore. Touring.
Stop 12 (7/4, 540mi) - Regina, CA. Overnight.
Stop 13 (7/5-7/7, 161mi) - Saskatoon, CA.
Stop 14 (7/7-7/10, 380mi) - Calgary, CA. For the Stampede.
Stop 15 (7/10-7/13, 79mi) - Banff NP. Standard NP Plan.
Stop 16 (7/13-7/16, 526mi) - Vancouver, BC.
Stop 17 (7/16-7/18, 141mi) - Seattle, WA.
Stop 18 (7/18-7/20, 173mi) - Portland, OR.
Stop 19 (7/20-7/23, 253mi) - Crater Lake.
Stop 20 (7/23-7/27, 520mi) - Yosemite NP. Extra Day.
Stop 21 (7/27-7/30, 179mi) - Sequoia NP. Standard NP Plan.
Stop 22 (7/30, 351mi) - San Diego.
I guess my first question is - is this plan a little too ambitious? I'm a little concerned with some of the 400+ mile stretches, though I have recently done some similar lengths. In 2015, I drove from San Jose to San Diego via Highway 1, which took about 10 hours and was 500+ miles. And last fall I took a late-night trip from San Diego to Joshua Tree, went on a 4.5 mile/2 hour hike in the morning, then drove back home via the Salton Sea in the afternoon (~400 miles).
Secondly, is there anything I can skip or anything I'm missing out on within the route? I'll admit that stops 9 to 11 are probably expendable, but I wanted a more direct route to Saskatoon that didn't seem as much like I was going out of my way to go there.
Finally, and this one is more directed to the vehicle aspect of the trip, but I'm planning this trip in a 2006 Porsche Cayman. For reference, it's a low two-door, two-seater sports car with somewhat limited storage capacity and no spare tire (but it's a helluva lot of fun to drive). Is that a crazy idea? Are there any road surface concerns with any potential campsites that I should be aware of? I did plan on joining AAA to alleviate some of the driving concern, but will that be enough?
And aside from the concerns regarding vehicle condition, is the packing aspect even feasible? I need a tent, sleeping bag, sleeping mat, clothes, camera bag, hiking equipment, cooking equipment, tools, and food/drinks. My plan for food was to stop at groceries between parks for the first stretch and fill up 2-3 days worth each time (with additional camping-ready meals for emergencies). Is that doable given the locations and timeframes?
I should also mention that I'm not really an experienced camper. I've been on a handful of weekend camping trips in the last few years, but usually with friends who A) are more experienced campers, and B) drive trucks capable of carrying many things. So please take that into account as well.
Any and all help would be appreciated. Thanks.
