What This Is

ONE GUIDE.
EVERY
ADVENTURE.

California has nine national parks, 280+ state parks, and thousands of trails, breaks, and launch sites. We put all of it in one place — every region, every activity type, with the local knowledge that most guides skip.

Local Knowledge

Written by a Northern California outdoor obsessive who has done these trips. Not scraped from the internet — verified on the ground.

International-Ready

Permit systems, gear requirements, real distances, unspoken rules. Every entry closes the gaps that trip up first-time visitors to California.

Filter Everything

Search by activity, region, difficulty, and season. Find exactly what you want to do, exactly when you can do it.

AI Trip Planner

Ask it anything — build an itinerary, decode a permit system, find a dog-friendly trail near Tahoe. Included with your guide.

Built For
International travelers

You've come a long way. California's scale, permit systems, gear requirements, and unspoken rules are genuinely confusing — this guide closes every gap.

Adventure-focused visitors

Not here for the theme parks. You want to backpack, surf, climb, fish, or paddle. This guide tells you exactly where, when, and how.

Trip planners doing the research

You love the planning as much as the trip. This is the single source that replaces 40 browser tabs and six half-useful Reddit threads.

AI TRIP
PLANNER

A planning assistant trained specifically on California's outdoors — ask it to build a three-day itinerary, decode a permit system, or figure out whether a trail is actually hikeable in November.

It knows the guidebook content, the real permit odds, the gear assumptions that trip up international travelers, and the unwritten rules locals don't bother explaining.

Outbound AI
Late September in the Eastern Sierra is the sweet spot — crowds are gone, aspen are turning gold, and temperatures are manageable. Here's a 3-day loop from the South Lake trailhead in Bishop Creek Canyon: Day 1 → Bishop Pass Trail to Dusy Basin (7 mi, 2,700ft gain). Camp at lower Dusy Basin — permits required from South Lake TH, book through Recreation.gov 6 months out. Day 2 → Day hike to Knapsack Pass with views into Palisade Basin. No permit needed for day excursion from established camp. Day 3 → Return via Bishop Pass. Gear notes: temps drop to 25°F at night by late Sept, layer system essential. Bear canister required — Bearikade or BV500 fit well in most 50L packs.
