Wild camping in the UK isn’t exactly a walk in the park

Unless your idea of a park includes boggy hills, sideways rain, and zero phone signal... Whether you’re getting lost (on purpose) in the Scottish Highlands or tackling a multi-day slog through Snowdonia, a solid adventure watch is a must. And if it charges with sunlight? Even better—because plug sockets aren’t exactly growing on trees.

In this guide, we’ve rounded up the best Garmin solar watches for wild wanderers. From the tough-as-nails Instinct to the feature-stuffed fēnix, we’ll break down why each one’s a trusty trail companion.

Grab your compass (just in case), and let’s find the watch that’ll survive your wildest UK adventures.
