We walked the Baztan in May. It’s a solitary route. Not for everyone but we are used to walking quieter routes with limited services. It’s very different from the Frances or the Le Puy for that matter. This might be useful - i copied it from a post I made on another thread.
We stayed in a mixture of accommodation as suited the stages - we decided as we went along. We relied on Gronze for information There are a few ways to cut it - we walked in 5 days.
Day 0 - Bayonne - Refuge Saint Jacques (14 places, modern, clean, lovely welcome from volunteers, you can reserve)
Day 1 - Espelette - Hotel Euzkadi (a splurge - and fabulous dinner)
Day 2 - Urdax - Monastery albergue - we decided on this short day to make the most of our hotel and Espelette, stay at the Monastery, and have the steep climb that follows in the morning rather than the afternoon. Happy with that decision.
Day 3 - Ziga - Posada de Ziga - lovely host, demi pension
Day 4 - Lantz albergue municipal
- we were going to continue to Olague, but we’d had a long tough day (not due to kms, but wet weather and lots of water flowing down the mountain).
Day 5 - Pamplona.
We rang on the day / day before for the Monastery, Ziga and Lantz. For the Monastery and Lantz, to make sure someone was available to come with the key and to find out what options we had for dinner. We were the only two in both Albergues.
We saw one pilgrim on the first day who was walking on to Urdax so we didn’t see him again. We saw three other pilgrims later, walking in reverse from Pamplona.
Hope you have better weather than we did. Lots of rain for 4 days out of 5 - but we loved the Baztan anyway
