Actually the Mythen region has a myriad of climbs/hikes possible, and can get confusing as much of the internet sites for that region are in german. Just to add clarity I am giving a trip report of the "normal route" to Grosse Mythen that I did over the weekend.

Grosser Mythen Hike (mods, please feel free to move it to a more suitable thread).

Route summary:Schwyz (450m) –Holzegg (1450) -G Mythen (1899) –Holzegg (1450)-Alphthal Brunni (1100)- Einselden (~900).

Participants: My son aged 9, and I, 35, male.

Hike details:

We started from Schwyz Bahnhof, it takes half an hour walk to reach the start of the hike, called the “Forum Mythen”, you'll see prominent signs; in fact up to this point it is common with the Ibtergeregg cycling route. The yellow hiking signboard there said it is 4h 20 mins to G Mythen (which meant we would need 3h based on our recent previous hikes such as Rigi and Pilatus).

We marched toward Holzegg through the bergwegs/shortest way up, this wasn’t so pleasant because the earth was still very wet. Too much flora and fauna. You are under dense forest cover for two hours, with no views and no sun until you reach Holzegg. That is when we get to see the impressive Grosse Mythen again, and our spirits soared again.

From Holzegg we hit the marked trail to G. Mythen. In one word, I would describe this hike as “delectable”, we just relished it. It is humanly impossible to lose one’s way with or without a map on this trail, and the trickier sections are secured by steel chains. I would still advise complete caution, as one misstep can send you tumbling down a few hundred meters, and rain/wetness can make it dangerous unless you are well-trained by climbing and hiking in the rain in safer places.

Once at the top, we had the mountain all for ourselves. The views were great (oh, but that's a cliche, which mountain in Switzerland does not offer views that make your heart sing in joy), we saw airplanes flying a couple of hundred meters below us, right between the Grosser and Kliene Mythen, and kiddo was thrilled. At the top of our own little world, we played, sang and danced, and ate for an hour, before heading down.

We decided to hike down toward Alpthal Brunni rather than Schwyz side to avoid the damp and dreary forested route. But when we reached Alpthal, we realized had missed the 6:08 pm last bus by a whisker. Out came the umbrella and the goodies, and we chomped our way leisurely to Einselden to catch the train home.
