The problem

Hiking alone in SoCal
shouldn't be the default.

Group hikes are scattered across Facebook groups and Meetup pages. Permit hikes fill up before you can find anyone to go with. Most apps optimize for likes, not lacing up your boots.

01

Trailheads aren't social.

Facebook groups are noisy. Meetup feels corporate. There's no place built specifically for hikers and riders to find each other in SoCal.

02

Permits go fast.

Mt. Whitney. Half Dome. Mt. San Jacinto in summer. By the time you find a group with an open spot, the permit window's already closed.

03

Solo isn't always safer.

Hiking alone limits where you can go and when. The right people make harder trails accessible — and remote ones safer.

Note from the founder

Hi, I'm Krystal.

I built TrailMates because I was tired of scrolling Facebook groups looking for someone to hike with, and missing permit hikes because I couldn't find a group in time.

I hike the same SoCal trails you do. So I made a better way to find people who actually show up.

No VC, no growth team, no algorithm. Just one solo founder building a tool for our community.

If something's broken, email me: support@trailmatesapp.com. I read every message.
