What to Pack for Hiking in San Dimas

When you're planning a hike in San Dimas, it's important to pack light and pack right. You want to be prepared with the essentials; we'll go over those below.

1. Water, Water, and Water!

There is nothing worse than being dehydrated on a hike. It's important to pack just the right amount of water for your day, usually about 1 liter of water per hour you plan to be hiking. It's important to stay hydrated throughout your hike, not just at the beginning.

2. Snacks:

It's also important to pack snacks for your hike. You'll want something that will give you energy but is also light and easy to carry with you. Energy bars are an easy choice.

3. Clothing:

When you're planning your clothing, it's important to think about the season in which you're going to be hiking. If it's in the winter months, you'll want clothes that are warmer and can protect you from the cold. Bring a pair of gloves or mittens too! It might also be good to wear a scarf, as it'll provide extra warmth.

In the summer months, you'll want to bring clothes that are light and breathable. You may also want to bring mosquito repellent if it's an option.

4. A Good Pair of Shoes:

When you go hiking in San Dimas, it's important to be smart about your shoes. You want to wear comfortable, sturdy shoes that are also appropriate for the season that you're in.

It's usually not a good idea to bring brand new hiking boots when you're going on a hike; always make sure that they've been broken in before you go out and about.

5. Flashlight:

This is especially important if you're planning on going out during the evening hours or even into the night. You'll want to bring a flashlight with you so that you don't trip over anything while balancing yourself and so that other hikers can see where you are.

6. First Aid Kit:

It's always a good idea to have a first aid kit with you when you're hiking, just in case something happens. It's important to know how to use the items in your first aid kit, just in case of an emergency.

7. Map and Compass:

If you're feeling lost or unsure where you are, it can be really helpful to have a map and compass with you. This will help you get back on track and find your way back to the main path or your car.

8. Sunscreen:

It's important to protect yourself from the sun while hiking, especially if you're going to be out for a long period. In addition to wearing light clothing, it's also important to wear sunscreen. You can even buy specific types that will protect you from bugs too!

9. Bug Spray:

If there are going to bug out when you're hiking, it's a good idea to bring bug spray with you as well. This will help to keep the bugs away and prevent any unwanted bites.

10. A Good Attitude:

Last but not least, it's important to have a good attitude when you're hiking. This means being patient, taking breaks when you need them, and staying positive. Remember that the hike is only as hard as you make it!
