My boyfriend and i are travelling from seattle to los angeles this summer over about 8 weeks, we will be spending just over a week in WA to see olimpic NP and North Cascades NP before driving down the west coast (over about 5/6 days) to San Francisco for a few days. At this point we do not know whether to head inland to Lake Tahoe or to stay on the coast and see Big Sur???

After one of these we are going to Yosemite and then through death valley to Las Vegus then to the Grand Canyon, Zion NP, Mesa Verde NP etc, then down to route 66 and along it back to LA.

Having never seen either can you recommend which would be better to see in terms of scenery - either big sur or lake tahoe?

Also does the rest of our route seem reasonable and if anyone has some suggestions as to anything else on route that we should see please let me know.
