Sure! Here are some recommendations on supplies and provisions you might want to bring for your hike to Alberta Falls with a group of children and a grandmother:

1. Water: Make sure to bring enough water for everyone in your group. It's important to stay hydrated, especially if the weather is sunny and warm. Plan on bringing at least one liter of water per person.
2. Snacks: Pack some healthy snacks to keep everyone energized during the hike. Granola bars, trail mix, and fresh fruit are all good options.
3. Sunscreen: Even if it's not particularly hot, it's important to protect your skin from the sun's rays. Make sure to bring sunscreen with a high SPF and apply it before you hit the trail.
4. Hats and sunglasses: To further protect against the sun, consider bringing hats and sunglasses for everyone in your group.
5. First-aid kit: Accidents can happen on hikes, so it's a good idea to bring a basic first-aid kit with bandages, antiseptic wipes, and any other necessary items.
6. Bug spray: Depending on the area, you might encounter bugs during your hike. Bring bug spray to keep them at bay.
7. Picnic supplies: For your picnic, pack a blanket or tablecloth, plates, cups, utensils, and napkins. Don't forget to bring food that doesn't require refrigeration or heating, such as sandwiches, fruit, and chips.
8. Trash bags: Make sure to pack out everything you bring in, so bring some trash bags to properly dispose of any garbage.
9. Comfortable shoes: Make sure everyone in your group has comfortable shoes suitable for hiking. Closed-toe shoes with good traction are best.
10. Layered clothing: Although the weather is forecasted to be sunny and warm, temperatures can change quickly. Bring extra layers, such as a light jacket or sweater, to ensure everyone is comfortable during the hike.

I hope this helps! Have a great time on your hike and picnic!
