Hi Cristian,
How wonderful!!! ENJOY your Camino!
My family of four did a portion of the Camino Portuguese from late May into early June 2018 and crossed over into Spain in Tui. I love what others have contributed! Here are a few things that worked for us.
1.My boys,12 and 15, BOTH preferred their athletic shoes to the boots they had. The terrain was the boardwalk, often streets, some trails but nothing their shoes couldn’t handle. I wore my boots but other than them staying dry during the rain, I didn’t need them for the terrain. We walked about 100 miles.
2. Although you’re traveling at a different time of the year then us, we often wore hats due to the sun. The wind made it easier to not feel the heat of the sun and my younger son got sunburned along the left side of his face and his ear walking along the coastal boardwalk. From then on he wore a bandana wrapped around his forehead and ears which protected the sunburn and further burning. This would also help keep sweat out of your eyes!
3. We had some rain but had our ponchos that covered us and our packs and they worked great! Inexpensive, lightweight and easy to carry.
4. We stayed mostly in albergues and only took lightweight sleep-sacks rather than sleeping-bags and they worked out really well.
5. We ended up packing too much and had to ship some things home after our first couple of days so my suggestion is less is better!
6. We had a couple of collapsible walking sticks which came in handy at times but not necessary.
I hope this is helpful information! If I think of anything else I’ll reach out!
Have a WONDERFUL time! I’ve included a few of our coastal photos just for fun.
Warm regards,
Heather
