The tunnel view in mid day light
The Yosemite valley can be sweating buckets hot in late September. Mid to high 30s C was typical and made me reconsider climbing the Glacier Point without a massive camelback of cold water to avoid passing out.
Going to the NP impromptu and without too much planning also meant all the 'beaches’ and swimming spots came as quite a surprise. Especially when mountain lakes in most of Europe are often on no swimming list. Bringing swimmers in this case is highly recommended. I wish I could have taken a dip after hours of walking in the blazing sun.
Of course, as about 20 other enthusiasts, waiting for the money shot is well worth it.
