Sometimes I feel like the Twin Sisters Range next to Mount Baker is often forgotten about. The red tape with the logging company land ownership adds a bit to the weirdness and mystery. Armed with mountain bikes, this turned into a great multi-sport adventure traversing from South Twin to North Twin.

And we’re off!

Getting the legs warmed up with 2000 feet of vert on the bike

The boring foothills of Whatcom County

---

Looking ahead at South Twin

---

And south towards the rest of the Twin Sisters Range

---

Class 3-4ish scrambling most of the way especially if you took the ridge proper

---

---

This range is comprised of olivine rock, so sharp and grippy that it cut my hands and pack up a little

---

Mount Baker is the only real view since this range is quite small and isolated

---

Totally glissade huckable

---

Getting off South Twin and crossing the glacier to get up North Twin

---

---

Going up North Twin

---

The rock was a touch more chossy here compared to South Twin

---

But just as fun and engaging

---

I don’t even know what class ratings mean anymore

---

Bit of techy downclimbing from the false summit of North Twin

---

One last look at Baker from the summit of North Twin

South Twin and the glacier we had to cross earlier

Notes

• This was probably ~19 miles and ~7200 feet of vertical gain, with 10 miles and 2000 feet of vert of that on the bike. A little over 13 hours total.
• We went from South to North Twin, but I imagine it goes both ways. Maybe the bike stashing is a little easier this way. The only thing that was techy was getting down the NE ridge of South Twin, which had some rockfall potential.
• You can take the whole ridge proper and not get cliffed out for South Twin, but that’s maybe not the case for North which had some false summits and sub-peaks.
• South also had bomber holds while North was a bit chossier.
