Yup - that's what we did. Right smack in the middle of nowhere is the gorgeous Canyon Lake. When I say middle of nowhere, you have to kind of work to get at it. What they don't tell you when you reserve the Steamboat ride is that you have to negotiate miles and miles of narrow, hairpin turns up and then down a mountain, with few if any guardrails to stop you from plunging 2000 feet into cactus fields. Not that you would care about the cactus at that point. The views, on the other hand, are breath-taking!
We were told to quit driving after Tortilla Flat because "the road gets really scary"! Holy cow! If it got any scarier, they'd have to have outhouses on every corner!
The boat tour is 1.5 hours and very informative. The highlight was when we stopped and spotted about 2 dozen bighorn sheep up on the cliff tops. Amazing sight! They told us that, on occasion, one will miss his footing and fall into the lake. Luckily for them (and us), that didn't happen.
Poor RRR nearly died on the trek to the boat - very steep ramp and lots of walking (be careful what you wish for, we told her). They very kindly gave us a wheelchair to get her back up the hill.
After that, we decided to negotiate another steep, windy road to go to Tortilla Flat (Population: 6) for ice cream. Then a butt-clenching trip up and down the curves, with the sun rapidly setting.
Would I do it again? In a heartbeat! Great Day!
