We just finished up visiting 10 NP's that interested us on the west coast. We left May 30 th for Great Basin NP, spent 2 days there, then headed to Sequoia/Kings Canyon, spent 3 days there, then onto Yosemite NP, spent 3 days there. We then headed to Lassen Volcanic NP, spent 1 day there, then onto Crater Lake NP, spent 1 day there because the snow had roads closed. We then went to Redwoods NP and spent 3 days there. We then headed up the 101 along the coast of Oregon. Then onto Olympic NP and we spent 3 days there, we then took the ferry to Coopesville and onto North Cascades NP where we spent 1 day due to the strange hot weather, not normal. We then drove to West Glacier and visited Glacier NP, took the Going to the Sun Road in the 1930's Red Bus, we spent 4 days there. We then went onto Teddy Roosevelt NP and spent 1 day there and then onto home.
The only reservations we made were for Kings Canyon/Sequoia and Yosemite NP and stayed at private campgrounds. All in all it took 6 weeks and 8,600+ miles. After 6 weeks we were ready for home. Seeing 10 NP's in one big trip is a lot to see and take in. Take your time and don't try to do it ALL in one big trip. Have fun.
