Maps Do not underestimate the need for highly detailed maps—and the ability to use them—while hiking in Wales. Bad weather, confusing trail junctions, and livestock paths can complicate navigation. Get the Ordnance Survey “OS” Explorer Maps (about $12.50 each) with a scale of 2.5 inches to the mile. You can buy them at regional tourist offices, some outdoor shops, and online at leisure.ordnancesurvey.co.uk. The best atlas for getting around Wales is the Philips Navigator Cymru/Wales ($11; philips-maps.co.uk). Garmin users can also get an entire collection of digital maps on SD or MicroSD card: TOPO Great Britain, Southern England & Wales ($140; garmin.com).

Camping Most hikers use established campgrounds that have easy trail access (search by region at walestouristsonline.co.uk). Dispersed, or “wild,” camping is not allowed in most parks; ask permission on private land. B&BsIt’s the Welsh version of hut-to-hut hiking. Many inns will even shuttle gear ahead to the next lodge. Plan on $45 to $60/night.
Money Some U.S.-issued ATM cards may not work. Check with your bank before traveling.
Getting around Rent a car for flexibility, but use public transport if you’ll be mostly on trails. A Britrail Pass allows you to hop on trains anywhere in Wales, England, and Scotland ($535 for a 15-day, standard-class pass; britrail.com). Buses are best for accessing trailheads. In Snowdonia, the Sherpa Bus (snowdoniagreenkey.co.uk) runs most of the summer, accessing trailheads throughout
the region. Find schedules at traveline-cymru.co.uk and nationalexpress.co.uk.
